The chapel of Notre-Dame des Cyclistes is situated in the commune of Labastide-d'Armagnac. The chapel is all that remains of a 12th-century fortress of the Knights Templar. The Château de Géou was razed by the Black Prince in 1355.
In 1958, Father Joseph Massie, pastor of Créon-d'Armagnac, Mauvezin-d'Armagnac and Lagrange, was inspired by the chapel of Madonna del Ghisallo in Italy to make a similar chapel for cyclists. A year later Pope John XXIII agreed to make the old chapel a National Sanctuary of Cycling and Cyclists.
Numerous champions have donated their shirts, including André Darrigade, Jacques Anquetil, Louison Bobet, Tom Simpson, Roger Lapébie, Jean Stablinski, Bernard Hinault, Raymond Poulidor, Eddy Merckx and Luis Ocaña.
The chapel includes a stained glass window designed and created by Henri Anglade, a former rider of the Tour de France, to represent cycling. It was reportedly intended to celebrate a thaw in the intense rivalry between Fausto Coppi and Gino Bartali, as they shared a bottle (bidon) on the Col d'Izoard during the 1952 Tour de France.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
