Why yes, that is a LEGO Millennium Falcon perched inside a diorama of Docking Bay 327, the scene of Obi-Wan and Darth Vader’s battle. It was created by German builder David Wagner and measures an impressive 90cm x 100cm. The project required roughly 10,500 bricks, four months, and 1,000 € to complete.
