Lourmarin is the only village in the Luberon that sits in the valley rather than on a hilltop, and it has a different quality as a result — more open, more inhabited, less theatrical. It has a real daily market, good cafes, a 16th-century castle worth visiting, and a population that appears to actually live there rather than merely inhabit it for the summer.
The Château de Lourmarin is open to visitors and contains a collection of art and furniture accumulated over centuries; the courtyard and loggia are more interesting than the collections. The market on Friday mornings is excellent — local producers from across the Luberon bring vegetables, cheese, honey, and wine.
