The imposing Archbishop´s Palace at the Castle Square by the Prague Castle has been the seat of Prague Archbishops continually since the 16 th century. It was rebuilt many times in various styles – Renaissance, Baroque and Rococo features can be seen there. Especially the decorative frontage catches one´s attention.The original palace was built for Florian Griespek of Griesbach, the secretary of the Czech Chamber and confidant of Emperor Ferdinand I. in the first half of the 16 th century. Ferdinand I. bought the palace in 1561 and gave it to the Prague Archbishop Antonin Brousa of Mohelnice. It has been a residence of Prague archbishopric ever since.The Archbishop´s Palace was radically rebuilt as a Baroque building in 1676. Archbishop Jan Friedrich of Waldstein entrusted the French artist Jean Baptist Mathey to make a project for it and the building work was led by Francesco Lurago.There used to be a ditch between the Prague Castle and the Archbishop´s palace and it was filled up in the 18 th century. The palace was rebuilt once again by J. J. Wirch to look harmonized with the Prague Castle. The frontage was adorned with Rococo decorations.
