This 17th century "watchtower" marks the east point of Hull Citadel. Built 1681-90, the citadel was a massive triangular fort incorporating earlier defences alongside the river Hull. It was levelled in 1863-4

The watchtower is a remnant of the original citadel. For years it was in East Park in Hull in the "Khyber Pass" as a place for children to play on.
