The old Wan Chai Post Office, erected between 1912 and 1913, was listed as a Declared Monument in 1990 and now serves as the Environmental Protection Department Resource Centre. The L-shaped structure is the oldest surviving post office building in Hong Kong and is a simple pitched-roof structure with attractive gable ends and mouldings. The Chinese couplet on the entrance facing Queen's Road East says: "If we foul our world that sustains us, what then shall we eat? Scorn hygiene that protects life, where then shall we live?" The building services include a reference library and a touch-screen environmental information system.
