Sluice Gate
At this gap in the outer bank, it has been suggested that a sluice gate stood here, and when opened, would allow for flooding along the outer bank. But this seems unlikely because there was no retaining bank to hold this water and it would have been too shallow to be a serious obstacle to those attacking the bastions.
