Christchurch Mansion and Park
The Ancient House on Buttermarket. Now a branch of the Lakelands chain of stores, its pargetting is definitely worth the walk.
Also, for architecture enthusiasts, the Willis Building. The first commercial construction by Norman, now Lord Foster, this building has won numerous awards and was in 1991 made into a Grade I listed building - the youngest building ever to receive such a status.
Note however that the building is in commercial use and so is not as such open to the public.
A walk by the docks can be of interest, especially as most of the old former grain store buildings on the dockside are being demolished and being replaced by new luxury apartments, high-rise offices and entertainment complexes.
The Ipswich Museum. Now merged with the Colchester Museum, first opened in 1847 and though small compared to any of the London museums, entrance is free and there are some interesting exhibits.
