Sitting on a pretty, pedestrianised square is the so-called Maison Louis XIV. Built in 1643 by a wealthy shipowner and furnished in period style, this is where Louis XIV lived out his last days of bachelorhood before marrying María Teresa. Half-hour guided tours (with English text) depart several times daily in July and August.
Alongside, and rather dwarfed by its more imposing neighbour, is St-Jean de Luz' Hôtel de Ville , built in 1657.
