This chapel is located at Moussy, one of the many possessions of the commandery of Compesières (or Geneva), belonging to the Order of the Hospital of Saint John of Jerusalem, situated in Switzerland. At Compesières, a large part of the structures of the commandery’s headquarters are still preserved. The chapel of Moussy is mentioned in a document dated to the year 1277, but it is not until the seventeenth century that other references to the site appear.
The church has a rectangular plan and is surrounded by buttresses. The main doorway is located on the north-west façade; it should be noted that the chapel does not follow the usual east–west orientation. The portal is semicircular, with two columns with capitals on each side. The building underwent modifications, particularly in the mid-fifteenth century, during the time of the commander Guy de Luyrieux, identified by his coat of arms. The interior was also divided by a wall and a Gothic window was opened on the south-east side. Above the entrance portal there was a rose window, now blocked. After the Revolution the building was converted into a dwelling, at which time further alterations were made.
