Ipswich Museum is a registered museum of culture, history and natural heritage located on High Street in Ipswich, the county town of Suffolk. It was historically the leading regional museum in Suffolk, housing collections drawn from both the former counties of East Suffolk and West Suffolk, which were amalgamated in 1974.
The original foundation of 1846, devoted primarily to Natural History, was moved to new premises in High Street in 1881. In about 1895 Christchurch Mansion, a large 16th-century house near the town centre in Christchurch Park, was given to the town. It was developed as a second venue under the same management and curatorship, devoted particularly to fine and decorative arts. Both are parts of one institution and draw on the same central core of collections. The entire service was merged with that of Colchester on 1 April 2007 to form Colchester + Ipswich Museums. It is one of Ipswich's main features.
