Cromwell is a town in Middlesex County, Connecticut, United States. Being located in the middle of the state, the town has a nickname “Crossroads of Connecticut''. The town is named after a shipping boat that traveled along the Connecticut River (which runs along Cromwell). This boat was named after Oliver Cromwell, the Lord Protector of the Commonwealth of England. In 1651, settlers first arrived in this area. Then Cromwell was a part of Middletown and in 1703 it formed its own separate parish.
