Christchurch Mansion is a substantial Tudor brick mansion house within Christchurch Park on the edge of the town centre. It is now owned by the town and since 1895 has formed one of the two principal venues of the Ipswich Museum.
The Grade I listed building mansion houses a collection of pottery and glass, a contemporary art gallery and a collection of paintings by artists including John Constable and Thomas Gainsborough.
There are rooms preserved as past inhabitants would have known them, complete with original items of fine clothing. The house sits within a 70 acres (28 ha) public park which features many beautiful trees, rolling lawns and ponds.
Christchurch Park was originally the grounds of the Priory of the Holy Trinity, with an area of many square miles, coming up to the medieval town walls. During Henry VIIIs dissolution of the monasteries, the monastery was dissolved and the land was purchased by Sir Edmund Withipoll, who built the mansion in 1548-50, the ground floor of which remains largely as he left it.
In 1894 the mansion was bought by Felix Cobbold, from a syndicate of property developments, saving the building from demolition.
