The extension of the Piarist college building is one of the buildings included in the implemented Revitalization of the Castle Hill in Litomyšl project. It was completed in June 2015. The building, designed by the Burian Křivinka Architects studio, is connected to the Piarist dormitory and includes the new municipal hall and library of the Faculty of Restoration of the University of Pardubice. The extension on the corner of Jiráskova and Zámecká streets in Litomyšl is a partially sunken two-storey building with a small pavilion at the attic level, which is to help urbanize the free space next to the Piarist dormitory and at the same time provide the necessary space for restoration. The building respects the original building line and the existing height of the neighboring cornices and thus completes the important urban space with a contemporary building. The extension of the Piarist dormitory cost 23 million crowns and was paid for with European money.
