Castellers is one of the most endearing and spectacular Catalan traditions, which can be seen at most Catalan festivals. A team of strong Catalans form a human tower, before a courageous kid of no more than 5 years old climbs to the top and nervously waves to the crowd. The record Casteller acheived a precarious ten people high tower. Don't get too close to the action, as the towers often collapse under the extreme weight. Call 93 402 4616 for more information.
