The Archaeology Museum in Ibiza is a captivating institution that preserves, researches, and showcases the historical heritage of the Pitiusic Islands, which include Ibiza and Formentera. These islands, distinguished by classical authors from the larger Balearic Islands of Mallorca and Menorca, have a rich and diverse past spanning over three thousand years.

Located in the historic district of Dalt Vila, in Cathedral Square, the museum is a significant landmark in Ibiza's old town. It is housed in several buildings, including the ancient Salvador Chapel, the old university, and the Santa Tecla Bulwark. This unique location offers visitors not only a journey through time but also stunning views of the harbor, the Marina, and the modern cityscape.

The museum's exhibits provide an in-depth look into the island’s prehistoric, Phoenician, Punic, Roman, and Moorish periods. Some of the most noteworthy artifacts originate from the Phoenician settlement of Sa Caleta and the cemetery of Puig des Molins, which is regarded as one of the most significant Phoenician and Punic archaeological sites in the western Mediterranean. Two prominent pieces in the museum's collection are the original Roman statues discovered during the construction of the city walls, which once adorned the main entrance to the old town.

Founded in 1907, thanks to the donation of the Archaeological Society of Ibiza’s collection, the Archaeology Museum has since expanded through further contributions and excavations. The museum’s comprehensive collection traces the history of the Pitiusic Islands up to the Catalan conquest in 1235, offering visitors a deep and enriching experience of Ibiza and Formentera’s vibrant past.

The Bastion of Sant Bernat, part of the historic Dalt Vila fortifications in Ibiza Town, is a remarkable reminder of the island's turbulent past. Constructed in the 16th century to protect the city from pirate raids and foreign invaders, this bastion is one of the oldest defensive structures in the Balearic Islands. Situated on the western end of the town’s coastal fortifications, it offers sweeping views of the Mediterranean Sea and the surrounding area, making it a popular stop for visitors exploring the ancient walls.

The bastion forms part of a larger network of seven interconnected bastions that encircle Ibiza's Old Town, all of which are accessible through a series of well-marked pathways. Each bastion showcases different aspects of the island's military history, from the advancement of military technology to the daily lives of the soldiers stationed there. The route from Sant Bernat leads to the nearby bastions of Sant Jordi and Sant Jaume, passing by the impressive Ibiza Castle (Castell de Eivissa), which was once an army barracks.

Originally constructed during Spain's Golden Age, the bastions, including Sant Bernat, played a critical role in defending Ibiza’s residents and securing the island’s prosperity. Today, the site is open to visitors and offers a range of exhibits, including military uniforms, armor, and artillery from the 16th to the 18th centuries. The interactive displays provide a hands-on experience, allowing guests to try lifting cannonballs or wielding replica swords while learning about the evolution of military strategy over three centuries.

Although plans were set in motion to transform the nearby Castle into a luxury hotel in 2007, archaeological discoveries have since put the project on hold. Nonetheless, the Bastion of Sant Bernat remains a key historical attraction, where visitors can step back in time and witness the might of Spain’s military past amid stunning sea views and centuries-old stonework.

The Castle of Ibiza, or Castell d'Eivissa in Catalan, can be argued to be the heart of the island. The castle grounds are located at the top of the fortified Upper Town. The castle is comprised of numerous buildings that include the Tower of Homage, the 8th century Almudaina, the governor's home and the 18th century infantry barracks.

The original foundations of the castle were created in the 12th century, though additions and restorations were continued for hundreds of years. Unfortunately, the castle fell into extreme disrepair and is now in a partially derelict state. Recent restorations have allowed portions of the castle to be open to the public.

Reconstruction efforts have been primarily focused on the Sant Jaume Bastion and the Sant Pere Bastion. Each of these bastions offer exhibitions that are open to the public. While visitors cannot enter the main castle, it is worthwhile to tour both of these bastions and the castle grounds.

The Sant Jaume Bastion is now a military museum. It houses a weapons exhibition with a focus on military technology from the 16th and 18th centuries. Visitors are welcome to touch the items on display, which include cannons, mortar, muskets, helmets and swords.

The Sant Pere Bastion shows the history of the castle. Tourists can see how the city wall was built through an audio visual display. The exhibition includes a reproduction of Renaissance-era scaffolding. Both bastions were designed by Giovanni Battista Calvi in 1555.

The buildings are open from Tuesday through Sunday throughout the year. During the winter months, from October to March, the hours are 10 AM to 4:30 PM on weekdays and 10 AM to 2 PM on weekends. From April to September, hours are 10 AM to 2 PM Tuesday through Sunday. The buildings are closed on bank holidays and from December 10 to February 28.

Whenever you visit the Dalt Vila, make sure to go up to the Baluard de Santa Lucía. This is the largest bastion in the fortified Old Town of Ibiza – designed in 1575 by the Swiss military engineer Giovan Giacomo Paleari Fratino (1520–1586), known as El Fratin or Il Fratino ("The Little Friar"), who served the Spanish Emperor Charles V and his son Philip II.

The structure has a rather unusual, asymmetrical plan, with original canons still seen at the top, that once guarded the upper town. Part of the bastion is the so-called Polvorin, a building that used to serve as a powder and weapons depot – currently an exhibition hall. The bastion is also frequently used as a venue for concerts or other events, including parties for the International Music Summit.

Other than that, Santa Lucía offers fantastic views over the harbor and the Gulf of Ibiza, as well as onto the roofs of the old houses of the Sa Penya district, formerly a fishing quarter and now one of the town’s most picturesque neighborhoods.

The Bastion of Sant Joan (Baluard de Sant Joan) is a prominent feature of the fortified old town of Eivissa, located on the northern side of the historic area. As one of the seven bastions depicted on the flag of Ibiza, it stands as a testament to the island's rich defensive architecture and historical heritage.

Perched high on the fortifications, the bastion is crowned with beautifully maintained gardens, offering visitors a serene spot to take in the panoramic views over the La Marina district and the vibrant harbor. During sunset, the Tower of the Baluard de Sant Joan is especially picturesque, casting a medieval silhouette against the Mediterranean Sea.

The bastion is part of the larger fortified structure of Eivissa's Dalt Vila, a UNESCO World Heritage Site, and serves as an iconic reminder of the town's strategic significance throughout history. Its elevated position not only provided military advantages but now serves as a prime location for enjoying the beauty and charm of Ibiza's old town.

The Bastion of Sant Jaume (Baluard de Sant Jaume) is located on the southwestern side of the fortified Dalt Vila district in Ibiza. As one of the seven colossal bastions that rise from the walls encircling the Old Town, it stands as a testament to the region’s historical defense strategies and Renaissance architecture.

Inside this imposing bastion, visitors will find a comprehensive display of Renaissance weaponry and military technology. The exhibits provide insight into the development of armaments and fortifications used to protect the town and its inhabitants throughout history. Among the showcased items are bombs, pistols, swords, lances, and halberds, accompanied by informative plaques detailing their use and historical context.

The bastion is also home to interactive exhibits, making it an engaging experience for visitors of all ages. Children can try on replica armor, handle some of the weapons, and even attempt to lift cannonballs, bringing a tactile dimension to the historical displays. This hands-on approach allows guests to connect more deeply with the past and the region’s martial heritage.

Beyond the exhibits, the bastion’s viewing platform offers a stunning panorama of Ibiza’s Old Town and the surrounding landscape. The terrace, lined with historic cannons, provides a perfect vantage point for those wanting to capture the beauty of the dark green mountains and the picturesque cityscape.

Opened to the public in 2008, the museum within the Bastion of Sant Jaume welcomes visitors from spring through fall, Tuesday to Sunday, with additional group viewings available during the winter by prior arrangement. Easily accessible on foot or by bus, the bastion is situated near other notable attractions, including the Capella de Sant Ciriac, the Museu Puget, and the Plaza Reina Sofia, making it an essential stop on any tour of Dalt Vila’s historic offerings.

One of the defensive bastions built throughout the Renaissance period, the Baluard de Sant Pere is a UNESCO World Heritage Site found in the heart of the walled enclosure of Dalt Vila, now open to the public. Otherwise known as Portal Nou (New Gateway), this is one of the two main entrances to the Old Town of Ibiza, located next to the park of Queen Sofia.

Crowned with the coat of arms of the Crown of Aragon, the bastion links the park with Plaza del Sol through a stair-filled tunnel: 50 meters long and 3 meters high. The name Portal Nou is probably due to the fact that it replaced the old gateway of dels Aiguaders, which disappeared following the construction of the Renaissance walls. It was designed by the architect Giovanni Battista Calvi.

The Baluard de Sant Pere contains a museum with audiovisual presentations detailing the ingenious construction methods used on the city’s ramparts. Among other things here you will find the original 16th-century wooden doors, intriguing displays of ancient weaponry and other artifacts. Also, climbing to the upper terrace, will afford you an excellent view of Ibiza. The site also frequently hosts open-air concerts.

Located in the heart of Ibiza Town, Can Ventosa stands as a testament to the island's cultural vibrancy and dynamic history. Originally constructed in 1925, this large building initially served as a textile factory specializing in sock production, providing employment opportunities for many local women. The factory operated until 1956, after which the Ministry of Defence took over the building for administrative purposes. Later, it was repurposed as a warehouse and repair shop, reflecting the building’s adaptability over the decades.

In 1995, the building underwent a significant transformation when the municipality of Ibiza acquired it with a vision to create a central cultural hub. Officially inaugurated as a cultural center, Can Ventosa now accommodates a variety of events ranging from theatre and dance performances to conferences and concerts. Its auditorium, featuring stalls and amphitheater layout, can host up to 450 people, making it one of the key venues on the island for live performances and gatherings.

Apart from the auditorium, Can Ventosa is also home to the municipal library, a space that has preserved the building’s original architectural charm while offering modern facilities. With over 140,000 members, the library is one of the largest and most well-frequented in Ibiza. The center also includes classrooms, a recreation club for senior citizens, and spaces for workshops and debates.

Whether you are attending a play, a concert, or a children’s performance on the weekends, Can Ventosa’s year-round programming ensures there is something for everyone. The building’s rich history and central role in Ibiza’s cultural life make it a must-visit for anyone looking to immerse themselves in the artistic and historical essence of the island.
