At the end of the Toulourenc gorges, built on the outposts of the Mont Ventoux, Montbrun suddenly hoves into view, displaying its cliff of serried ranks of houses, drawn upwards towards the sky like the pipes of an organ.

Covered with red ochre hued tiles, the narrow houses of Montbrun rise on 3 or 4 levels, battered outwards at their base to gain a more solid purchase on the rock, for all the world as if they were seeking the deepest possible roots. The castle is no more than a ghost of its former self, but legend has it that there was accommodation for 100 nobles, their retinue and 200 horses. Today visitors climb up to the site in the summer heat in search of a breath of wind.

The Calade du Grand Soleil - a street paved in stone - giddily descends the slope leading to the Notre-Dame gate, one of the 4 entrances to the old fortress. Together with the belfry, the church is one of the exterior signs of wealth of Montbrun. As for the baths they have been healing respiratory ailments and rheumatism since Roman times.
