Prague Castle
When the Přemyslid dynasty settled on the current site of Prague Castle, the two castles maintained opposing spheres of influence for approximately two centuries. The zenith of Vyšehrad was during the second half of the 11th century, when Vratislav II transferred his seat from Prague Castle to Vyšehrad, and the original fort was remodeled as a complex comprising the sovereign's palatial residence, a church, and the seat of the chapter. The period of growth ended around 1140 when Prince Soběslav moved his seat back to Prague Castle.
