En un regard
Le château en bref
Trélon Castle, in the Avesnois (Nord), is the seat of the de Mérode family, established on the site of a medieval fortress that passed to the Châtillon-Blois family in 1249 and was besieged in 1478. Acquired by the de Mérode family in 1577, the estate was raised to a marquisate in 1625, and became French in 1678. The present building replaced the former fortress in the 18th century; it was remodelled in 1860 by the architect Clément Parent in a Louis XIII style, with tall chimneys, upswept roofs and a chapel with a cylindrical tower. Occupied by Wilhelm II in 1918, heavily damaged during the Second World War and restored in 1945, it has been partially open to visitors since 2017 and is surrounded by a park containing two giant sequoias dating from the mid-19th century.
