St. Mark's Square, Square in Gornji Grad–Medveščak, Zagreb, Croatia

St. Mark's Square is a square in the old part of Zagreb, Croatia, known as Gradec or Gornji grad. It is home to St. Mark's Church, a Roman Catholic church that is believed to date back to 1291, and several important government buildings, including Banski Dvori, the Croatian Parliament, and the Constitutional Court.

The square has been at the heart of Zagreb's upper town since the medieval period, with the church dating back to the late 13th century. Over the centuries, it became the site of key government buildings, and in 2006 a renovation led to a ban on protests and rallies, which was partially lifted in 2012.

The square takes its name from St. Mark's Church, whose roof displays colorful tiles with the coats of arms of Zagreb and Croatia. It is a place where people often stop to admire the church facade and the surrounding buildings, and it serves as a backdrop for official ceremonies and gatherings.

The square is easy to reach on foot from the surrounding old streets, and its central location makes it a natural point to pause and look around. Visitors should keep in mind that the area is often busy with official events, so some parts may be closed off at times.

The square has been the setting for presidential inaugurations, with several presidents taking their oath there between 1992 and 2015. In 2020, a protest rally turned violent, drawing attention to the square's role as a stage for both celebration and conflict.
