St. Angel's Castle ticket price has risen, 12 euros, at that time at the door a little hesitant to enter, because online people say there is nothing good inside. Think about it. Come in. Then because of the pain of money, did not rent an interpreter, little regret, some do not understand. It is only possible to know that this was the first Tomb of a king. Later, it was built into a castle by the Pope. It had military defensive function and some Pope had fled to take refuge here. Personally, I think it's still very interesting inside. The architecture is simple and simple. I don't understand it very well and I think it's very interesting.
