Nestled on the banks of the Ourcq River, in the shadow of the ruins of the impressive fortress, lies the charming town of La Ferté-Milon. La Ferté-Milon Castle was founded at the end of the 14th century but was never completed due to the assassination of the Duke of Orléans in 1407. Nevertheless, you'll find interesting remains here, such as the impressive façade with its window openings, the machicolations, and the low reliefs, the most remarkable of which depicts the Coronation of the Virgin. Magnificent views over the Ourcq valley can be admired from the castle's forecourt... Other monuments you can visit in La Ferté-Milon include the Saint-Nicolas Church, with its 16th-century stained-glass windows depicting scenes from the life of Christ and a vision of the Apocalypse, and the Church of Our Lady, dating from the 12th to the 16th centuries, where the famous fable writer Jean de La Fontaine married Jean Racine's cousin. Literature enthusiasts should definitely visit the Jean Racine Museum, dedicated to the life and work of the famous playwright, which houses many memorabilia from his paternal grandmother's house, where the writer spent his childhood.
