Academy Palace, Neoclassical palace in Royal Quarter, Brussels, Belgium.

Academy Palace is a neoclassical building on Rue Ducale in Brussels, built between 1823 and 1828 by Charles Vander Straeten and Tilman-François Suys. Its grey stone facade has a rusticated ground floor with arched windows, a taller storey with tall rectangular windows framed by Ionic pilasters, and a modillion cornice topped by an attic. The side projections carry relief panels of 1879: The Arts by Antoine Van Rasbourgh, Letters by Herman, Sciences by H. Sterckx and Medicine by Auguste Braekevelt. A balustrade with urns and a black-and-gold gate enclose the garden.

The building was constructed in 1823 by architects Charles Vander Straeten and Tilman-François Suys as a residence for Prince William II of Orange. After the Belgian Revolution of 1830, it served as military quarters before becoming an academic institution later in the 19th century.

The palace is home to two royal academies, one devoted to sciences and arts, the other to the French language and literature. During public events, the building opens its doors to a wider audience, and the Marble Room is considered one of the finest reception halls in the city.

The palace stands at Rue Ducale 1, between Rue Lambermont and Place du Trône, just east of the Place des Palais and next to Brussels Park. Its garden, enclosed by a balustrade and entered between two allegorical lion sculptures by Félix Bouré, holds statues of Adolphe Quételet, Jean Servais Stas and Jules Destrée. The building itself serves the five academies, so the garden is the part a passer-by can see without an appointment.

The palace was built between 1823 and 1828 for Prince William II of Orange, who occupied it with his wife Anna Pavlovna for barely two years before the Belgian Revolution of 1830 forced them to flee to the Netherlands. The state then sequestered the building, and in 1842 its contents were shipped to his Palace of Soestdijk.
