Built on an old feudal motte, which is still visible and was completely destroyed during the Hundred Years' War, it was replaced in the second half of the 15th century by the castle, the remains of which can still be seen today. The Saint-François Tower remains as it was, with its Grisons base and rows of white stone. Halfway up the circle is the Cord of Saint Francis of Assisi, with its coils and knots. A Renaissance building was added in the 16th century, and new buildings were constructed in the 17th and 18th centuries.

Illiers Combray is not the banks of the Eure but of the Loir!

A pretty village centered around its abbey and gardens

Of course there is the castle but the rest of the village is really worth a stop (church, wash house, half-timbered house, etc.)
