Prague Castle is the largest ancient castle in the world (570 m long, on average 128 m wide,
area 7.28 hectares). Constructed in the 9th century by Prince Bořivoj, the castle transformed itself from a wooden
fortress surrounded by earthen bulwarks to the imposing form it has today. Rulers made their own additions so there
is a mixture of styles. Prague castle has had four major reconstructions, but it keeps its classical facelift it took
on in the 18 century during the reign of Maria Theresa. The castle has three courtyards and it has always been the
seat of Czech rulers as well as the official residence. Allow at least half a day (it does not include time for museum
visits) if you want to examine it in depth.
