Capela dos Ossos
Igreja do Sao Sebastiano
There is a small bone chapel on the side of this church, and one of several in the Algarve region others at Faro and Alcantarilha. You may have to pay 2 Euros to enter the chapel, the bell tower and the church, but the view from the bell tower is worth the price.
There is a great variety of things to see; The city center is sculped with traditional architecture and colors from the region. Beaches vary in shape and style from long sandy beaches to almost private ones hidden by cliffs. Ponta da Piedade is a beautiful spot with a nice lighthouse from where you can make boat tours to the natural caves. The harbour in the morning is full of activity, if you like to wake up early don't miss it. Also the fish market is an interesting spot.
