Richmond Tower, Gateway in Kilmainham, Dublin, Ireland

Richmond Tower is a stone gateway at the western entrance of the Royal Hospital Kilmainham in Dublin. It has a central arch with a metal gate, a window above, and crenellations between two towers, with the left tower taller and topped by a small turret.

Built between 1810 and 1811, the gateway first stood beside the River Liffey at Barrack Bridge. It was moved to its current site in 1847 after the opening of Kingsbridge Station caused traffic problems.

The tower is known locally as the West Gate because it stands west of the main hospital building. Its name comes from the Duke of Richmond, the Lord Lieutenant at the time of its construction, and it now serves as a welcoming entrance to the Irish Museum of Modern Art.

The gate is open during the museum's opening hours, and entry is free. It is best reached on foot from the city center or by public transport, and the area around it is flat and easy to walk.

The architect Francis Johnston secretly placed his own coat of arms above the arch, hidden behind a wooden panel painted to look like stone. It was discovered when the tower was dismantled and later replaced with the Royal Hospital's coat of arms.
