Today, castles seem to just be giant fortresses but I would like to know how they looked when they were fully furnished. How were they decorated? What treasures were stored there? Are there a few castles that were especially beautiful?
It is quite a broad subject because castles varied quite a lot depending on location, time of construction and wealth of the constructor; u/valkine talked about Caenarfon Castle specifically in another question
This is a part of the inside of Castello Maniance in Siracusa, Italy. It was built from 1232 to 1239 during a large castle-construction effort by Emperor Frederick II.
I do find it particularly beautiful but this doesn't really say much about what other castles looked like
