In the town's principal church, the 13th-century Eglise St-Jean-Baptiste, at the corner of rue Gambetta and rue Garat (tel. 05-59-26-08-81), Louis XIV and the Spanish Infanta, Marie-Thérèse, were married in 1660. The interior is among the handsomest of all Basque churches. Surmounting the altar is a statue-studded gilded retable (altarpiece). The interior is open to visitors Monday through Saturday 9am to noon and 2 to 6pm, and Sunday 3 to 6:30pm.
La Maison Louis XIV is more richly furnished with antiques and mementos than La Maison de l'Infante, interesting, and more densely loaded with souvenirs. It also has wax figures representing the important figures of the drama associated with this late-17th-century Franco-Spanish alliance.
