Monument record BNB 008 - Post Medieval flood defence bank, visible as an earthwork.

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 eastern 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 regularity of the bank and drains on the Barnby side may support the interpretation that it was the later of the two to be built.
