Tour de Moulor, fortified castle in Loudervielle in the Hautes-Pyrénées, France

Tour de Moulor is a ruined square watch tower about nine metres tall, built of rough tan, beige and grey stone on a grey limestone summit above the Lac de Génos-Loudenvielle in Loudervielle. It rises straight to a flat, roofless top, with one rectangular window opening high on the front face and plants growing from the crevices. A chapel dedicated to St Madeleine stands on the same site.

The keep and chapel are documented in the 13th century as property of the Lords of Montlaur, vassals of the barons of Espagne-Montespan. In 1540 Dominique de Montlaur gave homage for the castle, two houses and four barns. The last Montlaurs to live there died in 1753 and 1754; the chapel was restored in 1995.

The name Moulor comes from the hill of Monlaur, where the tower stands, and the site belonged to the Lords of Montlaur, vassals of the barons of Espagne-Montespan. A chapel on the site is dedicated to St Madeleine and was restored in 1995. The last Montlaurs to live in the castle died in 1753 and 1754.

The tower stands on the summit of a grey limestone peak above the Lac de Génos-Loudenvielle, in the commune of Loudervielle in the Louron valley. The climb is on foot; the site has no facilities and no marked visitor infrastructure. The chapel on the site was restored in 1995.

The tradition of a tunnel linking the castle to the manor of Génos is recorded but described in the sources as impossible to believe. The keep and the chapel are both documented in the 13th century as property of the Lords of Montlaur, vassals of the barons of Espagne-Montespan. The chapel, dedicated to St Madeleine, was restored in 1995.
