Kilclief Castle

📍 Shore Road, Down

🏛️ Attraction

Last updated: 28 April 2026

Overview

Kilclief Castle (Irish: Caislean Cill Cléithe) sits on a low headland overlooking the Narrows of Strangford Lough, just 2.5 miles (4 km) south of the village of Strangford in County Down. The tower‑house dominates the tiny hamlet of Kilclief and offers a rare glimpse into early 15th‑century fortified domestic architecture. Its dramatic silhouette – twin projecting turrets linked by a high machicolation arch – is instantly recognisable from the water and makes for a striking photo opportunity.

History

The castle was erected between 1412 and 1441, making it the earliest datable tower‑house in the Lecale peninsula. It was commissioned by John Sely, who became Bishop of Down in 1429. Sely used the building as a summer residence, but his tenure is remembered more for scandal than piety. He cohabited the castle with Lettice Whailey Savage, a married woman, a breach that led the Primate of Armagh to demand her removal. When Sely ignored the ultimatum, Pope Eugenius IV was petitioned in 1441, resulting in the bishop’s defrocking and ejection from the castle.

During the 1601‑02 rebellion of Hugh O’Neill, the Crown garrisoned Kilclief under Nicholas FitzSymon, stationing ten warders to protect the strategic Lough. By the 18th century the building had fallen into agricultural use, serving as a granary and later as a farm store. In the 20th century it was taken into state care and is now managed by the Northern Ireland Environment Agency. Guided tours are offered in July and August, allowing visitors to step inside the stone‑vaulted chambers that have survived for six centuries.

What to See & Do

Kilclief’s four‑storey layout is compact yet packed with architectural curiosities. The ground‑floor chamber features a semicircular barrel vault constructed on wicker centring – a technique rarely seen today. Ascending the south‑east turret’s spiral staircase brings you to the first floor, where the stone‑vaulted room opens onto a window that has been carefully reconstructed from a surviving fragment.

The north‑east turret houses a series of garderobes, a medieval latrine system that once served three of the four floors. At roof level the high machicolation arch creates a dramatic drop‑hole, historically used to pour boiling water or oil on attackers. Stepped battlements crown the parapet, giving the tower its classic defensive silhouette.

Inside, the second‑floor fireplace is framed by a 13th‑century coffin‑lid repurposed as a lintel – an early example of architectural recycling. Local lore calls one of the rooms the “Hawks Chamber”, reputedly where Bishop Sely kept his hunting hawks and falcons. From the upper windows you can enjoy sweeping views across Strangford Lough, with the distant outlines of Ardglass and the surrounding Lecale coastline.

The surrounding grounds are modest but pleasant. A small car park sits opposite the entrance, and the nearby Kilclief Beach offers a sandy stretch of shoreline perfect for a post‑castle stroll. For wildlife enthusiasts, a short walk to Cloghy Rocks (0.9 mi away) often yields seal sightings, while Ballyhornan Beach lies just over a mile to the south.

Getting There

Kilclief Castle is accessed via the A2 coastal road, with clear signage for the on‑site car park opposite the entrance. Parking is free and limited to a small lot, so arriving early in the summer months is advisable. The nearest town, Strangford, provides additional amenities such as cafés, toilets and a bus stop for services from Belfast and Newry. Public transport options are limited, so a car is the most convenient way to reach the site.
