The Royal Palace of Brussels is a monumental neoclassical edifice located at Place des Palais, serving as the King's administrative residence and principal workplace. Construction began in 1783 and was completed in 1934, with interiors designed by Alphonse Balat for King Leopold II. The palace's 50-meter longer facade exceeds London's Buckingham Palace in grandeur, while interior highlights include the striking Mirror Room featuring a modern art mosaic of 1.4 million beetle wing cases by Michel François. Though not a royal residence, the palace opens to the public during summer months, showcasing prestigious reception rooms where state functions, concerts, and official gatherings are held.
