Coll I Regàs House
After asking around a bit in the old town of Mataro, I found the house i Regàs Coll by Josep Puig. The guide explains that this house was restored by Caixa Laietana and has been declared a place of national cultural interest. The facade has sculptural elements by Eusebi Arnau. One of the things I liked most of the interior is the skylight, which gives spectacular light to the building. The whole house is full of columns, stairs, fireplaces etc. If you like the architecture of this time, you must visit.
