Cathédrale Saint-André

What is remarkable is that, despite its considerable size, the entire cathedral only consists of a single nave.

The cathedral is right on the Way of St. James and has a beautiful brass plate embedded in the ground in front of the church with an explanation about it

Saint-André Cathedral is a religious building in Bordeaux (France) that serves as the seat of the Archdiocese of Bordeaux. This cultural monument was classified as a monument historique in 1862 and is therefore protected as such.At 124 meters long, 18 meters wide in the transept, 23 meters high in the nave, and 29 meters high in the choir, the cathedral is the largest and most important religious building in the city of Bordeaux.The nave is a single-nave hall church, which is surprising for a building of this size, but more common in western France. The outer walls date from the Romanesque church, but the vaulting is from the late Gothic period.The west façade is completely unadorned and has no portal.On the north side of the nave is the Gothic royal portal, built around 1250.Construction of a new cathedral began around 1280, with an ambulatory choir and chapels in the style of northern French Gothic. The transept is distinguished by twin-towered facades at both ends, which compensates for the austere west front.The north portal, dating from the early 14th century, features rich sculptural decoration
with figures of the Archbishops of Bordeaux. It is surmounted by two 81-meter-high towers with pointed, Gothic spires. The Gothic structure was completed around 1350;
a new nave was apparently not planned.In the 15th century, the north transept rose window received a new flamboyant tracery,
while the south transept rose window retains the 14th-century tracery.During the French Revolution, the interior furnishings were destroyed
and the cathedral itself was converted into a barn.The cathedral has been on the UNESCO World Heritage List since 1998 as part of the "Way of St. James in France."de.wikipedia.org/wiki/Kathedrale_von_Bordeaux
