Throughout Portugal, the people like to decorate the exterior of houses and about any other type of building with ceramic tiles (azulejos). Not every building is decorated this way, but enough of them, so that you get used to it after a few days. These pictures were all taken in Lisbon, around the Castle Hill.
We are used to tiling interior rooms, like the kitchen, bathroom and WC - but never the exterior of a building. You can imagine how fascinated I was in the beginning, when seeing this phenomenon. Of course, I have seen tiling in pictures by Tom, so at least I was prepared in a way.
