In this small town, the attractive town centre is testimony to a splendid past. Emerging in the Middle Ages due to economic interest in salt, it preserves features of the mediaeval quarter with five of the seven entrance gateways and part of the wall.
In this museum it is possible to get to know the history of the salt producers, in the very spot where it was obtained, thanks to the conservation and reconstruction work on some of the more significant elements.
The source of the Deba River is situated in the foothills of Elgeamendi in Hiruerreketa.
