Castel Sant' Angelo and Ponte Sant' Angelo... by CandS
We didn't get to go inside but this unusual castle caught my eye...Castel Sant' Angelo was finished around 138 AD and has been used as a fortress, prison and palace. It now contains a museum of artillery and arms. I'm told the view from the palace are worth the visit though!
It is open in Summer Tuesday to Friday 9 am to 10 pm, Saturday & Sunday 9 am to 8 pm; Winter Tuesday to Sunday 9 am to 2 pm.
