Eglise Saint-Jean-au-Marché

This Gothic church was built in the 13th century and rebuilt in the 16th century. It is 77 m long, with a 17.3 m wide nave and a 9 m high aisle. The choir is 24.7 meters wide and 21 meters high. It has three naves and eight bays, the first three dating from the 16th century and the next five from the 13th century.
It is the site of an important historical event, as it was in this church that King Henry V of England married Catherine of Valois, daughter of King Charles VI of France and Isabeau of Bavaria. It was partially destroyed, the south and west, by the fire of 1524 and rebuilt after this event. The clock on the eponymous tower dates from 1789.
It lost the top of its tower during the night of August 23-24, 1911, when it collapsed onto the buildings on Rue Mignard. The Guillemette bell had been cast in 1524, and the other dated from 1902. The church was weakened and had to be supported by wooden and plaster props on the pillar legs.
The building was listed as a historic monument in 1840.[1]

The Saint-Jean-au-Marché church, whose presence is attested in the 10th century, is the center of one of the oldest parishes in the city of Troyes. Its name "au Marché" refers to the famous Champagne fairs which developed on its territory from the 11th century.
