Saint-Martin-de-Londres - Saint Martin (PiP)

In 1088, the existing parish was transferred to the nearby Benedictine monastery of Gellone (= Saint-Guilhem-le-Désert), which built a priory church here, probably consecrated around 1100.

The Church of St. Martin is one of the few buildings in Europe with triconch or trefoil plan, consisting of three apses around the crossing. Other examples can be found in Cologne, Müstair and Germigny-des-Prés.
