Next door to the Musée Toulouse-Lautrec, this mansion belonged to the Albi-born explorer Jean-François de Galaup (aka the Comte de Lapérouse), who made several pioneering naval expeditions around the Pacific between 1785 and 1789. Mysteriously, his ships disappeared without trace towards the end of their voyage; subsequent expeditions suggested they may have been wrecked on reefs near the island of Vanikoro, halfway between the Solomon Islands and Vanuatu.
Guided visits can only be arranged via the tourist office.
