Considering the Fundador in Guimarães?

Museu Alberto Sampier by evilprebil
When we went during the festival it was free, but it was a nice little excursion that I would recommend paying for also (2 euros I think). There's the quaint cloister of the Ingreja de Nossa Senhora da Oliveira and the rooms adjacent to it house the museum. Lots of nice pieces.
