The Macau Museum (Macau Scientific and Cultural Centre Museum) in Lisbon is Portugal's main museum of Chinese artefacts and artworks. Made to document Sino-Portuguese relations, the museum contains over 3,500 works of art including decorative artwork, costumes, a collection of opium-smoking paraphernalia and an important extensive collection of Chinese ceramics. The museum comprises two distinct and complementary sections, a section on Macau's Historical and Cultural Condition in the 16th and 17th Centuries on the ground floor and a section in its Chinese Art Collection on the first floor.
