Vojensky kostel svateho Jana Nepomuckeho is a church, used in season 2 as the outside of L’Hopital des Anges. It was used in various scenes when Claire and others visited the hospital.
Vojensky kostel svateho Jana Nepomuckeho is a short walk from Prague Castle. It is not immediately easy to find, being well hidden down narrow streets.
