Custume Barracks sits on the eastern bank of the River Shannon in the heart of Athlone, County Westmeath. Officially the headquarters of the Irish Defence Forces’ Western Command, the installation is home to the 6th Infantry Battalion, the 2nd Brigade Artillery Regiment and detachments of the 2 Engineer Company and the Medical Corps. While the site is a working military base and therefore closed to the general public, its layered history – from a 17th‑century cavalry encampment to a Cold‑War nuclear command centre – makes it a focal point for anyone interested in Irish military heritage.

History

1690‑1691: The birth of a garrison

The barracks trace their origins to the Williamite siege of Athlone in 1690. Sergeant Custume, serving with Maxwell’s Dragoons, fell defending the bridge that linked the town’s two banks. After the Williamite forces finally captured Athlone in 1691, a modest collection of wooden huts was erected on the west side of the Shannon to house cavalry and infantry units. These temporary structures formed the nucleus of what would become Custume Barracks.

18th‑19th centuries: Expansion and architectural ambition

During the Napoleonic era the British recognised Athlone’s strategic position and dramatically expanded the garrison between 1784 and 1815. A major rebuilding programme around 1810 produced the imposing twenty‑three‑bay, two‑storey range that dominates the site today. The façade is of coursed rubble limestone with red‑brick dressings, punctuated by a four‑storey pedimented clock tower of ashlar limestone. The tower’s cast‑iron weather‑vane and the hipped slate roof give the complex a distinctive silhouette that can be seen from across the river.

The main gate, a twentieth‑century addition, was constructed from the stones of a former caponnière that once guarded the original Market Square entrance. Relocated to facilitate the building of the Church of SS Peter and Paul, the gate is a tangible reminder of the barracks’ evolving relationship with the town.

Early 20th century: From British to Irish hands

The barracks remained a British installation (known as Victoria Barracks) until the Irish Free State took control in 1922. General Seán MacEoin renamed the complex Custume Barracks in honour of the 17th‑century hero. Throughout the War of Independence (1919‑1921) the site was a flashpoint, with Crown forces using it as a base for operations that deeply affected the local community.

Cold War: A hidden nuclear bunker

In the 1960s a secret underground facility was constructed beneath the barracks. Designed to accommodate up to 100 senior officials in the event of a nuclear exchange, the bunker featured a command‑and‑control centre, a map room, communications equipment (including a hotline to Whitehall), kitchen, sleeping quarters and bathroom facilities. A later, never‑realised plan called for a larger Integrated National Control Centre capable of housing 300 people for a month, but the project was abandoned.

Today

Custume Barracks remains an active Defence Forces site and the oldest occupied barracks in Europe. Its historic fabric is largely intact, and the clock tower continues to dominate the Athlone skyline. In September 2025 a major photographic exhibition – curated by veterans – opened in the Officers’ Mess, showcasing hand‑over images from 1922, historic buildings, and notable personalities associated with the barracks. The exhibition is scheduled for limited public viewing on dates to be announced.

Historic Photographic ExhibitionWhen open, the exhibition in the Officers’ Mess offers a visual narrative of the barracks’ evolution.

Because the site is an active military installation, interior tours are not offered and the perimeter is fenced. However, the riverfront promenade along the Shannon provides excellent photographic angles of the clock tower and the barracks’ façade, especially at sunrise or dusk.

Practical Information
