The church was built by bishop Gerard de Cardaillac in the 11th century, over a church erected in the 7th century by St. Didier of Cahors.
It was consecrated by Pope Calixtus II on September 10, 1119, and completed around 1135.
The church, located in the city's centre, has the sturdy appearance of a fortified edifice: at the time, the local bishops were in fact also powerful feudal lords in their role as counts and barons of Cahors.

The façade was renovated in 1316–1324 by Guillaume de Labroue, cousin of Pope John XXII, confirms this impression: it resembles a heavy castle wall, consisting in a porch surmounted by a bell tower enclosed between two towers.
The six windows, as well as those on the porch sides, are rather narrow; the only elements characterizing it as a church are the magnificent portal with triple splays, surmounted by a gallery of small arches, and the large rose window.

On the northern side is a secondary façade in Romanesque style, also fortified.
