The Marc Sleen Museum in the Zandstraat in Brussels is dedicated to Sleen and his creations. It was opened in 2009. The museum organizes a special tourists' route in Brussels, based on several locations that appeared in "Nero" comic book albums, including the Black Tower, Palais de Justice, Kapellekerk, The Sablon, Brussels Central Station, the Grand Place and Manneken Pis. One has to make an appointment, though.
