Bouzov in its full perspective/as much as I can cover with camera

It looks cold!

Each room had large medieval chimney, each with different ceramic tiles.

The Grand Master of the Order of the Teutonic Knights from 1799 to 1939,[3] archduke Eugen Habsburg, decided to rebuilt it in the Romantic, predoninantly Neo-Gothic style, according to the plans of the prominent architects of its time Georg von Hauberisser (1841–1922) of the Munich Polytechnic University; he was the author of Munich and Saarbrücken's town-halls, and also very influential as builder of churches like the St. Paul's church in Munich. The alterations were carried out with the intention of making part of the castle open to the public. Bouzov was fitted with modern furnishings and equipment, including running water and central heating. The order was abolished in 1939 and the castle was confiscated by the fascists, occupied and looted by the Nazis during the WW II.[3] The castle was acquired by the Chief of the Gestapo R. Himmler, who forced the Strahov Monastery to sell it to him for one million crowns, as a present to A. Hitler.[4] After 1989 the Order of Teutonic Knights expressed an interest in the castle, but their request to have it returned to them has so far been rejected. (wiki)

That is very interesting. I have just Googled it. It is very interesting architecturally.

But you were right, it was very cold inside. I wonder how people lived there, but I feel in my heel, they knew how to make warm there inside.

Replace the roof with solar panels. People would hardly notice- wink.

We do not have so many suuny days in winter here, so it would hardly help. In the hospital, where I work, we have solar panels on the roof, but its exploitation during the winter is much much less, then was expected. This is solution for countries, which have many sunny days.
