South Mymms Castle

Also known as, or recorded in historical documents as; South Mimms; castle on the Lea; Super Lviam

In the civil parish of Potters Bar.
In the historic county of Middlesex (Modern Authority of Hertfordshire, 1974 county of Hertfordshire).

Motte and bailey castle probably built in C12 with occupation extending into C14. The motte was preceded by a timber structure. A castle assumed to have been built by Geoffrey de Mandeville, earl of Essex (d. 1144), on his manor of Mimms c. 1141, was discovered in 1918. Excavations in 1960-7 revealed a simple but well appointed motte-and-bailey castle, with a structure beneath the bailey bank which may have been the church granted to Walden in 1136 or may represent earlier manorial buildings. The castle seems to have been sacked by King Stephen's forces but pottery finds indicate the later domestic use of the bailey, probably in connexion with the working of the adjacent chalk pits. Charters granted to Manderville in 1141 mention his 'castle on the Lea' in terms that some have taken to be a licence to crenellate.
