Glenarm Castle Travel Guide

Glenarm Castle stands on the site of one of Northern Ireland's oldest estates, with a castle presence dating back to the 13th century. The original castle was established by the Bisset family, who made Glenarm their capital by 1260. This early stronghold included a kitchen garden, orchard, mill, and extensive grounds. The castle witnessed turbulent times, including a takeover by the O'Donnells in 1495 and eventual control by the MacDonnells in the early 16th century, who remain the estate's custodians to this day.

The present Glenarm Castle was built in 1636 by Sir Randal MacDonnell, 1st Earl of Antrim, but was burned down in 1642 during the Civil War. For nearly a century, it remained a ruin while the family resided elsewhere. The mid-18th century saw a major rebuilding in a grand Palladian style by the 5th Earl of Antrim, including elegant colonnades and pavilions. In the early 19th century, Gothic revival elements were introduced by Anne Catherine, Countess of Antrim, adding romantic turrets, battlements, and the distinctive Barbican Gatehouse. Despite a fire in 1929, the castle was restored, though some original features were lost. Artistic contributions by the 13th Earl's wife in the 1930s added unique sculptural and painted elements reflecting family history and mythology.

The Walled Garden, integral to the estate since at least the 18th century, was designed to supply fresh produce to the castle household. It originally employed many gardeners and featured specialized glasshouses for tender fruits. Over time, the garden evolved from a purely functional space to include ornamental plantings. After a period of neglect in the late 20th century, restoration efforts beginning in 2001 revitalized the garden, opening it to the public in 2005. Today, it features decorative herbaceous borders, fruit gardens, and art installations, continuing to evolve with new additions each year.

Glenarm Castle remains the private residence of the McDonnell family, Earls of Antrim, who have been in Glenarm for nearly 600 years. The estate is a vibrant cultural hub, hosting the annual Highland Games and the Dalriada Festival, celebrating Scottish and Irish traditions. Since 2012, it has also been a venue for major outdoor concerts and the Summer Madness Christian festival. The castle and gardens attract over 100,000 visitors annually, offering a blend of historical depth and lively community events.

Set along the picturesque River Glenarm valley, the estate encompasses extensive grounds including historic woodlands, a deer park, and scenic views stretching from the sea inland. The castle’s architecture reflects a layered history, from Palladian elegance to Gothic romanticism, while the gardens provide tranquil and scenic spaces. Features such as the lime tree-lined driveway, yew and beech circles, and the obelisk sculpture add to the estate’s unique character.

Visitors can explore the Walled Garden from May to September, enjoying its horticultural beauty and art. The castle itself offers tours on select dates and can be booked for group visits. Throughout the year, Glenarm Castle hosts festivals and events, including the colorful Tulip Festival in May, a major family music and food festival in July, and a magical Christmas Experience in December. These events enrich the visitor experience, making Glenarm Castle a dynamic destination that honors its heritage while engaging contemporary audiences.
