Three times larger than the Palace of Versailles and out sizing Buckingham Palace by four times, Istana Nurul Iman is the largest residential palace in the world. This US$350 million structure has 1788 rooms and 257 bathrooms; designed by Filipino architect Leandro Locsin, the palace is only open to the public three days in a year during Hari Raya but if you want to catch a glimpse of it at any other time of the year, then check it out from Taman Persiaran Damuan.
