Saint Mark's Church and Square, Zagreb (must see)

Saint Mark's Church and Saint Mark’s Square form the political and historical heart of Zagreb’s Upper Town, occupying the space where the medieval settlement of Gradec once governed itself. The square developed as a civic centre after the 1242 Golden Bull of King Béla IV granted Gradec the status of a free royal city. Over time, it became the focal point for administration and public life—a role it continues to hold today.

Saint Mark’s Church is often described as one of the oldest architectural monuments in Zagreb, with elements such as a Romanesque window on the south façade and the semicircular plan of Saint Mary’s Chapel pointing to a 13th-century origin. However, the church was largely rebuilt in the 14th century as a three-nave Gothic structure, with ribbed vaults supported by sturdy columns.

The central highlight, the richly decorated southern portal, is located on the exterior right side of the church as you face it from the square. Considered among the finest Gothic portals in Central Europe, it features fifteen sculpted figures of the Holy Family, Saint Mark, and the Apostles. To find this detail, walk toward the right-hand entrance of the building; once there, look for the intricate shallow niches that house these medieval statues.

The church’s most recognizable feature—the colorful tiled roof—was added in 1880 and represents the building’s crowning glory. Visible from across the Upper Town, the roof displays two distinct coats of arms: the emblem of the Triune Kingdom of Croatia, Dalmatia, and Slavonia on the left, and the city of Zagreb on the right. To find the best view, stand in the center of the square and look for the vibrant red, white, and blue tiles that form these large heraldic shields.

Inside, the atmosphere becomes more intimate, defined by works by Croatian artists Ivan Meštrović, Jozo Kljaković, and Ljubo Babić. Sculptures by Ivan Meštrović are located primarily within the chancel and near the altars; look for his powerful, modern interpretations of religious figures, which contrast with the church’s restored frescoes and gilded ceiling finished in gold leaf.

The square surrounding the church is framed by key state institutions, including the seat of the Croatian Government, the Parliament building, and the Constitutional Court, while the Old City Hall stands at one corner. Renovated in 2006, the square has also served as a stage for modern political life, including presidential inaugurations until 2020. Security measures introduced after a 2020 attack have at times limited access, affecting the usual flow of visitors, so checking current access to the square and church in advance is advisable.
