Château de Flamarens, Medieval castle in Flamarens, France

Château de Flamarens is a stone castle in the commune of Flamarens, Gers, southwestern France. Its main wing has a flat grey-stone front with a grid of small rectangular windows, a central dark wooden door, and a small wooden shelter above the middle windows. A tall round tower of light-beige stone blocks stands to the right, with a crenellated parapet on corbels and three tall rectangular windows on its upper faces.

A castrum is recorded at Flamarens in 1289 and was probably remodelled in the 14th century. Between 1469 and about 1475 Jean de Cazanove carried out building work for Jean de Grosolles, and the northern part was built before 1536 by Georges Dauzières for Arnaud de Grossolles. Windows and interior decoration were altered in the 18th century, and a fire partly destroyed the castle in 1943.

The castle is a private residence, not a public venue; its name comes from the commune of Flamarens in the Gers. It opens to visitors only in July and August, when the grounds and exterior can be seen. The 1943 fire left parts of the building roofless, a state visible from the outside.

Access to the grounds is seasonal and guided tours can be arranged for larger groups. It is helpful to check availability and group size requirements in advance to plan your visit properly.

The castle was listed as a monument historique in 1965, and in 2023 a mission identifying endangered buildings selected it for attention. It remains privately owned and opens to the public only in July and August, so the interior is rarely seen outside those two months.
