The main square is the heart of Caminha — small, paved in granite, ringed by low whitewashed houses and a few cafés that put their tables out as soon as the weather allows. The space is dominated by the Torre do Relógio, a square medieval clock tower that was once part of the town's defensive walls and is now its most photographed building.
In the centre of the square stands a sixteenth-century Renaissance fountain, the Chafariz de Caminha, attributed to João Lopes the Elder. It is small, well-proportioned, and decorated with carved heraldic shields — a quietly elegant piece of work for a town this size. The square is at its best in the early evening, when locals come out to talk and the light hits the granite at a soft angle.
