Holbeach appears to have prospered in the post-Medieval period. Many buildings of this period survive, some of which are Listed. Industrial sites are also known from Holbeach. Early maps indicate malthouses and breweries towards the east of the town. Smithies and ironworks can be seen to be located north of the market square and old brick pits, now a nature reserve, are situated south of the High Street. Apart from the brick pits, no exant industrial sites of 18th or 19th century date are thought to exist. Fleet Hospital was formerly the Union Workhouse, replacing an earlier workhouse, now demolished, but located at the junction of Park Road and Park Lane. {1}{2}
