Two important lordships formed the basis of the current Hoeilaart: the lordship of Ter Heyde south of the IJse on the one hand, and the lordship of Holaer or Hoeilaart north of the IJse on the other. Here once stood the castle of the Ter Heyde lordship from the fifteenth century. That lordship ceased to exist after the abolition of the ancien régime. The current castle was built in 1858 on the orders of baron Jean de Man d’Attenrode (mayor of Hoeilaart from 1854-1878) and his wife Maria Carolina d’Ormesson. It is therefore not a remnant of the old lordship. BUT: the chapel and former closed farm next to it are. This building has now, as others have mentioned, been given a different function and dominates the view in the park.
