There are many stamp requests about European castles already, but I think it would be nice to make a set with some of the oldest or most famous and beautiful castles of Europe. It could include for example the Romanian Bran castle, the Czech Karlštejn castle, the Buda castle of Hungary, the Neuschwanstein castle from Germany, a French castle from the famous Loire region, and there are also requests for castles from Belarus.
Any other recommendations would be welcome, as I am not familiar with some of the countries' castles.
