Here is a video tour through Diocletian's palace in Split. Incidentally, the APs and I wanted to go to Croatia in May 2020, which was nixed for obvious reasons, and we might try again in 2023. If so, I'll put Split in the list and make some photos for my friend who is a scholar of the the Katte family the Tetrarchy.
