Beneath the Place Royale one finds the remains of the former palace and medieval remains of the city. One can walk underground between the BELvue Museum and the Rue Villa Hermosa. At the Rue Montagne de la Cour - Hofberg lies the Musical Instruments Museum (MIM), with the Art-Nouveau façade of the former Old England store. Opposite the museum is a brick house with gable, an imitation of the traditional houses of the town (1984). This site offers a view (direction Senne Valley) on the tower of the Town Hall (15th century) and the Basilica of Koekelberg (1971).
