Hussey Tower was built as part of a large manor house in the mid 15th century by Richard Benyngton, a wealthy local merchant.  It is one of the earliest brick buildings in the county and was influenced by both Tattershall Castle and Rochford Tower in Fishtoft.  In the 16th century it was owned by Sir John Hussey, hence its present name, who was executed by Henry VIII following the Lincolnshire Rising in 1536.  The Tower has been owned by the Boston Corporation since that time and the original manor house slowly declined until the Tower was all that remained.

The building is now in a poor condition as it has no roof and the brickwork, particularly at a high level, is deteriorating.  Pigeons roosting in the building leave toxic droppings which have to be removed annually and the Tower is often a target for vandalism.  Heritage Lincolnshire is therefore working on a project to secure the repair of the Tower and to reinstate a roof that will both protect the building and allow a greater level of access to it.

The Trust aims to improve the setting of the Tower and to develop the building as a visitor attraction which offers residents of Boston, and visitors to the town, another amenity area and another glimpse of the town's medieval heritage.
