The Oleśnica Castle (Poland) is a school building today. In its interior, there is a little left of its former glory. Originally built around the 13th century, the castle had many owners and was rebuilt many times. In the second half of the 16th century, building was remodeled to the Renaissance appearance we see today. The Hohenzollern family was the last owner until the end of the Second World War. There is not much to admire here, but it is great that the castle stands until today.
