Mouragia area of Corfu Town.
It was placed right above the main entrance of the 3-story building which today it's still occupied by private lodgings.
Having a closer look at the slab we can spot a lion with wings holding a shield with an ancient greek helmet on it. At the bottom right and left corners there are two cannons which point at the east and west respectively. At the right upper side something like a coat of arms could be seen.
So, judging from this slab, it is mostly likely that the building was used for military purposes. It may have been military headquarters, a place to store armory and ammunition.
It is also apparent that the slab is very clean, preserved and it doesn't show its age. There are lots and lots of this venetian slabs on the walls of the town (may one day I will cover them in one post) which are in urgent need of restoration, like the majority of Corfu's defences. It is about time to think about that!
