The Istana opens its doors for all to check out the President’s sweet digs along Orchard Road, set on the grounds of a former 19th-century nutmeg plantation. This annual open house offers guests a rare peek into the offices of the President and Prime Minister housed inside the charming neo-Palladian style main building. The Istana is open all day, so you can explore the sweeping grounds, catch a myriad of live performances, join the guided tours available and take part in the Nature Guided Walks where you can learn more about the rich flora and fauna on the Istana grounds. Entry fee is $2 per person. It’s absolutely free for both Singaporeans and Permanent Residents.
