The church on the courtyard / market in the center has huge church bells. When they go off you can hear them from miles away.
There are a few bars scattered through the center. But this bar is the liveliest. You can sit outside and have a drink or two, or go inside and try some tapas. The people there are very friendly, and the drinks are quite cheap.
You will find writings and flags on Basque Seperatism everywhere. One of the biggest and can be found on the side of a mountain. You can see this easily from the center.
