In September 2018, the NPMK employees made a new photographic documentation of the current state of the former castle sanatoriums in Štiřín, Kamenice, Olešovice and Lojovice. All the buildings, except Kamenice, are in good condition. Castle Kamenice is under reconstruction. Photos of the Sérynyi´s villa in Olešovice, where used to be the Medical House during “Operation Castles”, were newly acquired for the Archive of P. Pitter and O. Fierz.
