Portuguese tiles are world famous too. You can find fine plates, artistic tiles, specially in blue and white.
Those in the pic were in a nearby park, though they were a bit damaged by local graffiti...
Portugal is world famous for its sheets and towels, so we went for a little shopping in the morning. It's not fabulous stuff, but the quality is good, there is a wide variety and the prices are definetly better than in Spain. There are a few shops around the historical centre.
