The collegiate church of the castle housed the tombs of the Counts and Dukes of Vendôme, including Jeanne d'Albret and Antoine of Bourbon, parents of Henri IV.

In 1371, after the death of Count Bouchard VII, his sister, Catherine of Vendôme inherited the County of Vendôme. Her marriage with Jean of Bourbon-La-Manche gave birth to the House of Bourbon-Vendôme.

Unfortunately, this sanctuary was desecrated by the Protestant Huguenots in 1562 and by the revolutionaries in 1793. The church was demolished in the 19th century but its layout is materialized by yew hedges, planted in 1935.
