Head to the top of Le Castillet
This superbly preserved former prison is one of the enduring emblems of Perpignan. Its burnt-orange walls leave no doubt as to its Mediterranean locale, while the turrets and Catalan flag hint at the fascinating history of the region. The former main gate, Le Castillet, which dates back to the 14th century, houses a museum, where entry is free on the first Sunday of the month. Bring comfortable shoes: there are 142 steps to the top.
