Monument record NHC 022 - Post Medieval flood defence bank.

A probably post medieval flood defence bank is visible on aerial photographs as an earthwork crossing Castle Marsh for approximately 2 kilometres, centred on circa TM 476913, North Cove parish. This bank is the western of two earthworks which flank the channel known as Hundred Drain, possibly a former marsh creek that defines the line of the parish boundary between North Cove and Barnby parish across the marshes (see BNB 007 For the second bank). The two flood defence banks and drainage ditches on either side were probably constructed by the separate parishes, possibly at different dates, the greater irregularity of the North Cove bank and drains may support the interpretation that it was the earlier of the two.
