Visit Baron Palace, a massive mansion built by Baron Édouard Empain, a Belgian entrepreneur and architect who also produced the Paris Métro. Its distinctive architecture and placement have led to spreading rumors over the years. In its prime, the palace had luxurious gardens, gilded doors, and Belgian mirrors designed by Georges-Louis Claude. Built between 1907 and 1911, the mansion is covered with detailed animals and figures inspired by Orissa in India and Angkor Wat in Cambodia. Now long abandoned, the palace is said to be connected to underground tunnels which lead to the nearby Catholic Basilica where the Baron is buried. The Baron’s life was somewhat tragic, and long after his death, he remains a mysterious figure in city lore.
