Don't miss the Palacio del Mar’s aquarium, with its underwater tunnel and fascinating 360º view of marine fauna. The big attraction is the huge skeleton of the last whale to have been hunted and caught in local waters. There's also a history section about the region's fishing, shipping and ship-building industries. When you get hungry, try the delightful restaurant inside the aquarium. The complex opened in 1928 and was completely refurbished before re-opening to the public in 1998. The schedule changes, so call for details.
