Here is my 3/4 cutaway view inspired by King Anheg's observatory from the Belgariad, by David Eddings. I thought it would be cool to have a stone observatory tower overlooking the sea. It was a fun experience combining the medieval architecture and more fantasy inspired scientific equipment. Will definitely design more rooms like this in the future.
