Built in 1796 as a replacement for the original prison in Dublin, Kilmainham Gaol is located just outside of the city centre but is easily accessible via both public transport and any Dublin sightseeing bus tour.

Kilmainham Gaol was intended to replace the former dungeon-like prison in Dublin. Originally, cells were designed to house one inmate, but that soon changed thanks to over-crowding and an influx of prisoners, particularly during the time of the Great Famine in the mid-1800s.

Segregation of prisoners did not occur and men, women and children, up to 5 per cell, were expected to share the dark cells, with only one candle for light and heat per fortnight.

After the Great Famine, the East Wing was opened, intended to provide better conditions for inmates and to afford prison officers a 360-degree view of each cell. It is this part of the prison that is most famous.

After the Easter Rising in 1916 and subsequent years during the fight for independence, the prison housed some famous, political inmates including Eamon de Valera who would go on to become President of Ireland.

Entry to Kilmainham Gaol is by guided tour only, tickets for which can be bought from the OPW site. If you are spending 3 days in Dublin, then allow a morning to visit this historical site and to spend time in the museum which houses an informative collection of artefacts and exhibitions about Ireland, its struggle for freedom and the 1916 Easter Rising.

How to get there: Kilmainham Gaol is located in the Kilmainham area of Dublin, 4km from O’Connell Bridge in the city centre. It can be reached via car (approximately 15 minutes), by public transport (by bus or via the Luas), or on foot (50 minutes walk).

Glendalough flourished as a monastery for centuries until the 13th century when the diocese of Glendalough and Dublin were united, after which its status declined. The site was ruined by English forces in the 14th century and what we see today are the remains of the once famous Christian site.
