A big museum
This is an ethnographic museum which teaches you about the historic lifestyles of Asturias. It stands right next to the fairground, on the banks of the river. It's a very big museum (about 32,000m2), with several buildings, so you should allow yourself plenty of time to get a good like. The House of Valdes (XVII century) has an exhibition of Asturian photos from 1850, to 1965. The House of Gonzalez de la Vega has the bagpipe museum, showing bagpipes from Africa and several parts of Europe.
The heart of the museum is the pavilion from Expo 92, where there is an exhibition on Asturian cuisine and domestic life between 1800, and 1965.
