Rising above the rooftops of Tallinn’s Old Town, Saint Olav's Church is one of the city’s most prominent landmarks, with origins tracing back to at least the 12th century. Dedicated to King Olaf II of Norway, the church served as a focal point for the Scandinavian community in medieval Tallinn. Its tall spire functioned as a crucial navigational marker for ships approaching the harbor.

The church’s history is closely tied to its tower. Rebuilt and expanded over time, the spire reached an estimated height of around 159 meters in the 16th century, making it one of the tallest structures in the world between roughly 1549 and 1625.

A well-known local legend adds another layer to the site. According to the story, a mysterious master builder agreed to construct the tower but demanded a high payment, unless the townspeople could discover his name. As the tower neared completion, the townspeople grew anxious about the cost. Determined to learn the builder’s name, they secretly listened outside his home. One night, they overheard his wife singing a lullaby to their child, in which she mentioned his name—Olav.

When the builder reached the very top of the nearly finished spire, the townspeople called out his name. Startled and realizing he had been tricked out of his payment, he lost his footing and fell from the tower to his death. The church was then named after him.

Visitors can climb the tower to reach an open viewing platform, typically accessible from spring through autumn. The ascent is steep, but the panoramic view reveals Tallinn’s red rooftops, church spires, and the Baltic Sea stretching beyond. In the 20th century, the tower even served a practical purpose as a radio and surveillance point during the Soviet era. Today, the church is used by a Baptist congregation, continuing its long-standing role as a place of gathering while offering one of the clearest vantage points over the city.

Saint Catherine’s Passage is a narrow medieval lane connecting Vene Street with Müürivahe Street, following the outer wall of the former Dominican monastery. Dating back to the 13th century, the passage developed alongside the monastery complex and preserves sections of its original stonework. Overhead arches linking the buildings were added later to reinforce the structures and remain one of the passage’s defining features.

The passage takes its name from Saint Catherine and the adjacent Dominican monastery, founded in 1246. Along the northern section, you can see the remains of the monastery church, one of the oldest surviving ecclesiastical structures in Tallinn. Several tombstones are set directly into the walls. These belonged to burials associated with the monastery and date mainly from the 14th to 16th centuries.

Toward the southern end, the passage becomes a center for traditional crafts. A group of working studios, often referred to as Saint Catherine’s Guild, continues long-established artisanal practices. Here, visitors can observe glass-blowing, ceramics, leatherwork, and textile production, with many workshops maintaining techniques rooted in historical craftsmanship rather than modern mass production.

The passage is short and can be walked in minutes, but it is best explored slowly. Entry points are easy to miss, and the northern section near the monastery remains the most historically intact, while the southern end is more active with workshops. Unlike larger streets in the Old Town, this lane functions more as a preserved corridor than a thoroughfare.

At the center of Tallinn’s Old Town, Town Hall Square has functioned as the city’s main gathering place since at least the medieval period, with market activity recorded here as early as the 11th century. The square is framed by pastel-toned merchant houses and dominated by the Gothic Town Hall, completed in 1404, widely regarded as the oldest surviving town hall in Northern Europe. Look toward the southern side of the square to take in its full façade and tower.

The surrounding buildings, dating mainly from the 15th to 17th centuries, illustrate the prosperity of the city during its time within the Hanseatic network. Among them is the historic Raeapteek, located on the northeastern edge of the square. Established in the early 15th century, it is often cited as one of Europe’s oldest continuously operating pharmacies. Inside, a small exhibition presents early medical tools and remedies, offering a glimpse into centuries-old practices.

As you cross the cobbled square, smaller details begin to stand out. Near the center lies a circular stone marked with a compass rose. Stand directly on this stone and look around. You can align your view to spot five of Tallinn’s historic church spires rising above the rooftops, including those of Saint Olaf’s Church, Saint Nicholas’ Church, Saint Mary’s Cathedral, Church of the Holy Spirit, and Saint Michael’s Church. A short distance from this marker, slightly off-center toward the Town Hall side, lies an L-shaped stone linked to a local legend: it is said to mark the spot where a priest was executed after a violent dispute. In summer, cafés extend their seating into the square, and depending on their layout, the temporary flooring may partially or completely cover this subtle piece.

In warmer months, café terraces fill the edges of the square, while markets and open-air events bring a steady flow of activity. The annual Tallinn Old Town Days festival transforms the area into a stage for performances and exhibitions. In winter, the square is centered around a large decorated Christmas tree, linked to a tradition often associated with the Brotherhood of the Blackheads, who are said to have erected one of the earliest public Christmas trees here in the 15th century.

The Tallinn Town Hall stands as one of the best-preserved Gothic town halls in Northern Europe, and the only one of its kind still standing in the region. First mentioned in 1322 and completed in its current form in 1404, it reflects the wealth and independence of a medieval trading city at the height of its Hanseatic influence. Until 1970, it served as the center of civic life, where the town council governed, trade was regulated, and public ceremonies were held.

From the outside, the building is defined by its limestone construction, clay-tiled roof, and a slender spire rising about 64 meters above Town Hall Square. The tower is crowned by “Old Thomas”, a weather vane figure first installed in 1530, symbolizing the city’s watchful guardian. Along the façade, a series of arches supported by pillars form a sheltered arcade, where merchants once gathered during poor weather. In earlier times, this space also served as a place of public display, where offenders could be chained to a pillar as a form of punishment.

Inside, the Town Hall reveals a series of spaces designed for both governance and representation. The main room, known as the Citizens’ Hall, could accommodate around 100 people and continues to host concerts and events today. Elsewhere, the Council Chamber features carved wooden details dating back to the 14th century, while benches, arches, and decorative elements reflect the craftsmanship of the period. Copies of historic tapestries line the walls, with the originals preserved in the Tallinn City Museum.

Today, the Town Hall remains an active cultural venue, open to visitors during the warmer months. You can explore its interior, attend an event, or climb the tower for views across the red rooftops of the Old Town.

Perched along the edge of Toompea Hill, the Kohtuotsa Viewing Platform is one of the most popular vantage points in Tallinn, offering a wide and uninterrupted panorama over the city. Easily reached on foot from the Old Town, the platform sits in a slightly more open and informal setting compared to other viewpoints, allowing visitors to take in the view without the visual interruption of nearby walls or towers.

From here, Tallinn unfolds in a broad sweep. The red rooftops of the Old Town stretch out below, punctuated by church spires such as Saint Olav’s Church. Beyond the medieval core, the view extends toward the modern city, the harbor, and the Gulf of Finland. The perspective offers a clear sense of how the historic center fits within the wider urban landscape.

Kohtuotsa is also known for small contemporary details that contrast with the historic setting. A section of the wall near the platform often features changing graffiti, including the well-known phrase “The Times We Had”, which has become a recognizable visual element for visitors. This blend of historic panorama and modern expression gives the viewpoint a slightly different character from other spots on Toompea.

The platform itself is simple, with a raised area and safety railings that make it a comfortable place to pause. It is particularly popular for photography, especially at sunrise and sunset when the light softens across the rooftops and the sea. Free to access and open year-round, Kohtuotsa Viewing Platform offers one of the most expansive and memorable views of Tallinn.

Built between 1894 and 1900 to a design by Mikhail Preobrazhensky, Alexander Nevsky Cathedral reflects the period when Estonia was part of the Russian Empire. It is dedicated to Saint Alexander Nevsky, the Russian prince who secured victory at the Battle of the Ice in 1242 on nearby Lake Peipus.

Its architecture stands in clear contrast to the surrounding medieval cityscape. Designed in the Russian Revival style, the cathedral features onion-shaped domes, richly ornamented façades, and layered decorative details that distinguish it from the Gothic and Baroque buildings nearby. As Tallinn’s largest Orthodox cathedral, its scale and elevated location make it visible from many points across the city.

Inside, the cathedral presents a richly decorated interior typical of Orthodox tradition. Gilded icons, mosaics, and painted surfaces create a dense visual environment, centered around the iconostasis that separates the altar from the nave. The interplay of light and gold surfaces gives the space a distinct atmosphere, differing markedly from the more restrained interiors of Lutheran churches in Estonia. The cathedral’s bells, among the largest in Tallinn, add another defining feature with their deep, resonant sound.

The cathedral’s history has not been without controversy. Built during a period of Russification, it was at times viewed as a symbol of imperial authority, and plans for its demolition were even considered in the 1920s, though never carried out. During the Soviet era, when religious practice declined, the building fell into disrepair. Since Estonia regained independence in 1991, the cathedral has been carefully restored and continues to function as an active place of worship, while also welcoming visitors interested in this distinct chapter of Tallinn’s past.

Rising about 20 to 30 meters above the surrounding city, Toompea Hill has long been the political and symbolic center of Tallinn. This limestone plateau has served as a defensive stronghold since medieval times, its elevated position offering both protection and wide views over the harbor and surrounding lands. In Estonian mythology, the hill is said to be the burial mound of the legendary king Kalev, raised by his wife Linda, whose tears are believed to have formed nearby Lake Ülemiste.

At the heart of the hill stands Toompea Castle, now home to Estonia’s parliament. The castle incorporates medieval foundations with later Baroque additions, including its distinctive pink façade completed in the 18th century. Rising above it is the Tall Hermann Tower, first built in the 14th century and still used for the daily raising and lowering of the Estonian flag. Nearby, the ornate Alexander Nevsky Cathedral adds a contrasting architectural presence with its 19th-century Russian Orthodox design.

Walking through Toompea, the setting feels more formal and contained than the lower town. Streets are lined with government buildings, embassies, and historic residences. Saint Mary's Cathedral, dating back to the 13th century and one of the oldest churches in Estonia, survived a major fire in 1684 that reshaped much of the hill. Inside, medieval coats of arms and memorials reflect centuries of noble influence and religious life.

Along the edges of the hill, several viewpoints open out across the city. These vantage points highlight the historic divide between the upper town and the merchant quarters below, while also offering one of the most complete views of Tallinn’s layout.

The Nunna, Sauna and Kuldjala Towers form part of Tallinn’s extensive medieval fortifications, among the 26 towers that still survive from what was once one of Europe’s most formidable defensive systems. Construction of the city walls began in the late 14th century and continued into the 16th century, eventually enclosing the Old Town with walls reaching up to 16 meters in height and several meters in thickness. At their peak, these defenses stretched roughly four kilometers around the city.

As you approach from inside the Old Town near Suur-Kloostri Street, the three towers line up along the wall from south to north. Kuldjala Tower is the southernmost and closest to the inner streets, often serving as the main access point. Moving north along the wall, you reach Sauna Tower, positioned just a short distance further along the same defensive line. Continuing northwest, toward the open green space of Tornide Square, stands Nunna Tower, positioned closest to the former convent area, hence its name.

Today, this section of the wall is open to the public, allowing visitors to walk through the towers and along connecting passages. The Nunna, Sauna, and Kuldjala Towers provide a practical way to engage with Tallinn’s defensive history. Rather than viewing the walls from below, you can explore them from within, gaining a clearer understanding of their scale and purpose. As part of the wider city wall system, they highlight how carefully planned and heavily fortified Tallinn once was, at a time when security was essential to protecting its trade and prosperity.
