The lush Lake Gardens (officially the Perdana Botanical Garden) date back to 1888, though they have expanded beyond their original size. More than 800 species of orchid can be seen at the Orchid Garden, while other tropical and subtropical plants flourish throughout the grounds. Boasting 92 hectares (227 acres), the park is a green oasis in the heart of the city. Adjacent to the gardens is Independence Square where, in 1957, the Union Jack was lowered to mark the end of British rule and the Malaysian flag was raised for the first time. In front of the square is the Mughal-style Sultan Abdul Samad House, a grand government building constructed in 1897. Next door, the Tudor Revival Royal Selangor Club, built in 1884, is open only to members, but you can admire its exterior.
