Train stations aren’t normally too high up on my list of attractions to visit (excluding London’s gorgeous St Pancras), but walking past Porto’s São Bento station we were drawn in by the flashes of blue and white through the doorway. Inside we found ourselves in a huge light-filled hall, covered with floor-to-ceiling blue and white tiled panels. You can see this type of painted ceramic tile – called azulejos – on the fronts of churches and houses all across Portugal, but these were some of the most impressive we saw. There are over 20,000 individual tiles covering the station walls that make up pictures of battles, coronations and other events in Portuguese history. They were painted by the famous azulejo painter Jorge Colaço, who started work in 1905 and finally finished them eleven long years of painting later.
