Caserne Guynemer, Military museum in Rueil-Malmaison, France.

Caserne Guynemer is the former barracks of the Swiss Guards in Rueil-Malmaison, now housing the Musée des Gardes suisses in its guard post. The long stone building has a central block with a steep grey roof, two round dormer windows, a triangular pediment carved with a crest and figures, a round clock face, and a tall arched doorway with dark wooden doors reached by steps. Symmetrical wings with red tiled roofs and rows of rectangular windows extend on either side, and a tall flagpole stands in front of the entrance.

Louis XIII formed the Swiss Guards company in 1616; its men reached Rueil-Malmaison in 1646 and lodged with local inhabitants. In 1754 Louis XV ordered three barracks, at Rueil, Courbevoie and Saint-Denis, and Charles Axel Guillaumot built the Rueil one in 1756 to the same design, housing some 800 men of the second battalion. The regiment was killed defending Louis XVI at the Tuileries on 10 August 1792; the Rueil barracks, enlarged in the early 19th century, is the only one still standing and has been a classified monument historique since 1974.

The museum opened in 1999, inaugurated on 9 November by Rueil mayor Jacques Baumel and Swiss ambassador Bénédict de Tscharner. Its objects and costumes trace the regiment created by Louis XIII in 1616, from the first guards lodged with local inhabitants in 1646 to the massacre at the Tuileries on 10 August 1792.

The museum is best reached on foot or by local transport and sits in a quiet part of Rueil-Malmaison. A visit takes about an hour and advance booking is required, especially for larger groups.

The museum opened in 1999 in the former guardhouse of the barracks. It was inaugurated on 9 November by Rueil mayor Jacques Baumel and Swiss ambassador Bénédict de Tscharner. The barracks itself, built in 1756, is the only one of the three Swiss Guard barracks still standing and has been a classified historical monument since 1974.
