If you want to come inside there is an entrance fee of one euro per person, but if you just want go up in the hill for a sight seeing its all free, it is very nice to see the view of the city from the top of the hill just near the entrance of the Castelo.
I love the view from the top, some visitors ride a bicycle and brought it up.:)
Fondest memory: I went up and down in a very high stairs, bit scary but nice feeling when you were on the top.
Favorite thing: The town’s main church looks down over the town centre where there is a small triangular square with some nice old, small houses plus a tourist information office which was shut when I visited in September 2010.
Tiles must be something very typical from the Mediterranean areas, but looking at this ones, I could feel I was in Andalucia (ok instead of Calle you can see Rua, but in Galicia is similar lol)
