Khoo Kongsi, officially known as Leong San Tong Khoo Kongsi, is the grandest Hokkien clanhouse in Malaysia and one of George Town’s most iconic heritage sites. Located at Cannon Square amidst a network of old shophouses, it was rebuilt in 1906 after a fire destroyed the original structure—featuring a magnificent ancestral hall, operatic stage, administrative blocks, and rows of terrace houses forming a tightly-knit clan complex . The main hall, Leong San Tong (Dragon Mountain Hall), showcases exquisite Southern Fujian craftsmanship—with detailed stone carvings, ornate wooden beams, gilded decorations, and a rich visual tapestry of murals and ancestral tablets. The site also houses a small museum tracing the Khoo family’s migration from Fujian, clan governance, and community influence in Penang’s development.
