Prague Castle is the world's largest ancient fortress, spanning a millennium of architectural evolution.
In short: Spanning nearly 70,000 square metres, Prague Castle is more than a royal seat; it is a sprawling architectural timeline. From Romanesque foundations to Gothic cathedrals and Renaissance palaces, this complex has witnessed centuries of power, fire, and occupation, serving today as the official residence of the Czech Republic's president.
The site’s history traces back to 870 with the construction of the Church of the Virgin Mary. By the 10th century, under Vratislaus I and his son Wenceslaus I, the complex expanded with two major religious structures. Over the following centuries, the castle evolved through distinct stylistic phases: a 12th-century Romanesque palace, 14th-century Gothic fortifications and church construction, and later Renaissance additions under the Habsburgs, such as the Belvedere summer palace.
The castle has functioned as a stage for pivotal historical moments, including the 1618 Third Defenestration of Prague and the 1648 looting of Rudolph II’s art collections by Swedish forces. Its role as a seat of power persisted into the 20th century, housing leaders from Tomáš Masaryk to the Nazi Reich Protector Reinhard Heydrich. Following the 1948 communist coup and the 1993 formation of the Czech Republic, it remains the official workplace of the nation's head of state.
Architecturally, the complex is a unique collage of styles. The Gothic St. Vitus Cathedral, finally completed in 1929, stands alongside the Romanesque St. George’s Basilica. Modern interventions, such as those by Jože Plečnik in the 1920s and 1930s, and later work by Bořek Šípek, ensure the site remains a living monument. Today, it is the most visited attraction in the Czech Republic, drawing over 2.5 million visitors annually to explore its diverse museums, gardens, and historic halls.
