We had a morning trip to Aveiro from Coimbra.  Back in the day it was a fishing port and also made salt.  Now it has a big university, tourism and wonderful art noveau buildings in the centre of town, with, of course, amazing tiles.

These photos don’t do it justice; the fishermen’s houses were originally painted in stripes (allegedly so they could find their way home), and the oddly shaped boats were originally used to transport salt; now they transport tourists on the town’s canals.
