Two Narrow Waters, not one

People often mix them up, but the tower by the water and the big Narrow Water house are two different buildings from two different times. The keep on the shore is a 16th-century defensive tower. The house came later, and belongs to the Hall family's story of running the estate and growing the town.

Look from the keep up towards the estate and spot the difference.

Why the castle stands where it does

Narrow Water Keep sits right where the river meets Carlingford Lough, the perfect spot to watch and control who came and went by water. The tower house and its wall date from the 1500s. It looks lovely now, but that spot was chosen for practical reasons, not the view.

Stand by the keep and look down the lough the way the lookouts once did.

The castle's front door was the water

The museum's account of Narrow Water records a landing place for boats just outside the east side of the castle wall. People arrived by water as often as by road, because back then boats were how you got about.

Find the spot outside the east wall where the boats once landed.
