2021 - Fortress, Castles, and Mansions in Maramureș
The 2021 album reveals the most representative castles, fortresses, and mansions in Maramureș, across a collection of over 200 images older or closer to our times and through an accessible, pleasant, and interesting historical synthesis. It reveals architectural beauties built with considerable effort by our forerunners, preserved and restored with care and devotion by those in whose care they were left. However, at the same time, ruined edifices are disclosed, reminiscent of the greatness of the old days, but whose fascinating stories still emanate a magic feeling.
