Often regarded as the world's largest private residential building, this royal palace 2 miles southwest of central BSB is the official home of the Sultan of Brunei. Set in extensive gardens and topped by a golden dome, it is alleged to contain 1,800 rooms. You can get an idea of its impressive size from the partially obscured views from the front gate—or by taking a boat tour along the Brunei River to the rear. Unfortunately, for 362 days a year that is as close as most normal people will get. The building only throws its doors open to the public for three days during the Hari Raya celebrations that mark the end of Ramadan and the Islamic new year. During that time, 10,000 people are welcomed inside and offered free food. If you're lucky enough to be around at that time, you will get a chance to marvel at the sumptuous decorations, and may even get a chance to meet the Sultan himself.
