Kilmainham Gaol Museum in Dublin, Ireland, is a former prison that operated from the late 18th century into the early 20th century. During its years as a detention site, Kilmainham held many Irish revolutionaries, including leaders of the 1916 Easter Rising, several of whom were executed on the premises.

Today the prison operates as a museum and site of remembrance. A new exhibition now on display explores the story of five former Free State soldiers who were executed during the Irish Civil War. The second phase of the exhibition opened on January 8 and includes a set of personal letters from one of the executed men — the first time those letters have been shown to the public.
These five ex-Free State soldiers were accused of desertion and charged with treason after joining an anti-treaty group in Leixlip. Still wearing fragments of their National Army uniforms, they were held at Kilmainham Gaol in 1922 and executed the following year. Terence Brady, Leo Dowling, Sylvester Heaney, Anthony O’Reilly and Laurence Sheeky — often referred to collectively as the Leixlip Five — are the focus of this part of the exhibition, which brings together the sparse material and testimony that survives about them.

A particularly moving element of the display is a group of letters written by Sylvester Heaney in the weeks before his execution. These personal writings describe his experience in custody and convey his reflections and regrets, offering visitors a direct, human perspective on the events that led to his death.
Other items in the exhibition document the early executions of the Civil War in 1922, situating the Leixlip Five within the wider, often brutal context of that conflict. The exhibition runs through March 31 and admission is free, allowing broad public access to these important historical records.

Kilmainham Gaol also runs guided tours that trace the site’s layered history, from its earliest prisoners and ordinary criminals to those who fought for Irish independence. The gaol is linked to major events including the 1798 rebellion, the Anglo-Irish War, the Irish Civil War and the 1916 Easter Rising, and it played a pivotal role in the fates of many involved in those struggles. Tour tickets must be booked online. Adult tickets are approximately $9, senior tickets about $6, and children and student tickets around $4.
