East Suffolk County Hall is a historic building located in St Helens Street in Ipswich.
The original county hall building was designed by William McIntosh Brooks and completed in 1837 as a prison and law court. It became the headquarters of East Suffolk County Council in 1906 and then the headquarters of Suffolk County Council in 1974 before they decided to move out of the building to more modern premises in 2003. The Council moved to Endeavour House in Ipswich the following year and County Hall is now owned by Rainbow Developments.
