Our mission is to educate, promote interest in, and advocate for the preservation of the historic castle of Kilwaughter. Caring for the past, building on skills for the future, bringing recognition to the region on the significance of local heritage, thereby raising awareness and attracting economic opportunities.


The original building known as Kilwaughter Castle was a four storey tower house in the Scottish Baronial Style. With a T-shaped layout, the tower house would have been incorporated into the main bawn wall for defence typical of new buildings erected during plantation era Ulster. In fact, many new planters received orders from the English court to build a stone house in the English style and surround it with a protective bawn wall, as part of their land grants. The bartizan turrets visible on the oldest part of the castle, are a common feature of the Scottish Baronial Style.

The original structure was constructed around 1622 by Patrick Agnew. Through time, the fortunes of the Agnews increased significantly and they enjoyed a position of power in the local and wider areas. During this time architectural fashions also changed, and the typical English style mansion came into vogue. Thanks to a period of relative peace in Ulster, social stability increased and the defensive tower house and bawn of the 17th century was no longer seen as a necessary or indeed a comfortable place to live.

In 1806, with his acquired wealth, Edward Jones Agnew, a descendent of Patrick's, ordered the first major extension of Kilwaughter Castle. The famous, and occasionally infamous architect John Nash (1752-1835), was hired to complete the designs. Nash is more famous for his development of Regent Street and the plans to transform Buckingham House to a Palace. Edward would have seen evidence of Nash's work first hand, not in London, but at William Stewart's newly constructed mansion: Killymoon, Co. Tyrone. Stewart was a cousin to Agnew and is likely to have made the introductions between Agnew and Nash. Killymoon Castle

Kilwaughter Castle Restoration Group was formed in September 2015. Now in 2017, in order to safeguard the future of the Castle a Community Trust with charitable status is being set up. The Trust’s aim is to stop further deterioration of the Castle, promote its fascinating history and make the building a source of pride for the local people and the Larne area. With the support of so many individuals and groups the restoration of the Castle is now becoming a reality.

Caring for this historic place and making our collections and archives accessible to as many people as possible for the benefit of this and future generations is our goal.


We are very grateful for the resources available through the Ulster Architectural Heritage Society (UAHS) From planning stages to general guidance on our restoration project, information and assistance has been invaluable.

UAHS works to promote the historic environment, encouraging the conservation, restoration and re-use of Ulster's built heritage to regenerate and sustain communities. In partnership with the Department for Communities (formerly Department of the Environment) UAHS has produced a comprehensive Built Heritage at Risk Northern Ireland Register, (BHARNI) for over 20 years. The online BHARNI Register can be found at: http://www.uahs.org.uk/
