Châteaudun Church of the Magdalene, Châteaudun

This former Augustinian abbey church dates from the 12th century, founded in 1120 by Thibault IV, Count of Blois and Dunois. Originally stretching about 80 metres long, it was the largest religious building in the historic County of Dunois. The south portal, with its finely carved Romanesque voussures, is the highlight — it spent centuries hidden behind the city's medieval ramparts and was only rediscovered during 19th-century works.
