We went to a museum in Porto that is free on Sundays. The free part was fortunate as the museum itself was quite boring, proving that art can be too conceptual to be interesting. The grounds of the museum, the estate of a benefactor of the arts, were a little more interesting.
From the other side of the river, Porto looks like a historical artifact, some sort of scale model of how it once was. It would be unreal if it wasn’t so real.
Near the port houses, there is a staircase that has been painted with humorous scenes of buildings in the area. The painter (painters?) was quite talented as the images are deceptively real when isolated, but even more fascinating in context.
