Asian Civilization Museum

It is a world class museum packed with fascinating information, and presented in interesting and innovative ways.
There are eleven galleries spread over three floors, and each themed gallery is integrated with virtual hosts (a hit with the kids), videos and interactive 'ExploreAsian Zones' which are learning zones designed for children.

If you are interested in textiles there are some breathtakingly beautiful Batik and Ikat, stunning fabrics from the hill tribes of Southern China, silk carpets, and many other beautiful artifacts in the South East Asia Gallery.
If ceramics is more your thing, the museum is well-known for its collection of white Dehua porcelain from China. Also known as 'blanc de chine', these finely moulded pieces are from the Ming and Ching periods.

The building is a fine example of colonial architecture. Designed by engineer J.F.A NcNair in the mid-1860s and built by convict labour as government offices, it was originally much smaller.
It was renamed 'Empress Place Building' at the start of the twentieth century in honour of Queen Victoria, and continued to house government offices until a major reconversion began in the 1990s.
Incorporate a visit to the museum with lunch out on the terrace, overlooking the river. The Siem Rep II Cafe has a good range of Indochine and western food, with reasonable children's menu.
