One of the oddities of Portugal is the mixture of buildings you find in most towns and cities. Alongside a modern villa you’ll find an old house, or alongside an apartment block will be a patch of unused land, and there are half-built structures all over the countryside. Partly a comment on the current state of the economy and partly seemingly that sometimes the owners just run out of the means to complete the buildings.
But the most unusual thing that I find about Portugal is the sudden sight of a completely derelict building in the middle of a town. It doesn’t matter where you go, there’ll always be a ruin. This particular example is in Aguas Boas, the next village over from Carris.
