Prague Castle is the largest medieval castle complex in Europe (at about 570 meters in length and an average of about 130 meters wide) and the ancient seat of Czech kings throughout the ages. It is Prague's premier tourist attraction.
The Bohemian Crown Jewels are kept here. Prague Castle is one of the biggest castles in the world (according to Guinness Book of Records the biggest ancient castle).
Several destructive wars and fires (and the subsequent renovations), along with differing political forces have combined to create an intriguing mix of palaces, churches and fortifications.
The Prague Castle was most likely founded in around 880 by Prince Bo?ivoj of the Premyslid Dynasty (P?emyslovci). According to the Guinness Book of World Records, the Prague Castle is the largest coherent castle complex in the world, with an area of almost 70,000 m².
