This afternoon I started researching for Castel san Angelo which is also known as Castello Argonese.
It looks as if I am going to need a few houses and a church or two to surround the works. The good news is that from the look of it on old maps, Taranto township only consisted of the island. all the other stuff is later modern works.
So nothing nearly as complex as Dubrovnik was to model ans no scratch built buildings this time.
