There are four round towers in County Dublin but the one in Clondalkin is the only one I have photos of. (I took a look at the one in Swords when I was a teenager) Anyway, the one in Clondalkin is notable for being the only round tower in Ireland which is thought to still have its original roof intact – there are no records of it having been reconstructed. It is made of stern stuff too. In the late 18th century, there was an explosion in a nearby powder-mill. The explosion of its 250 barrels of gunpowder demolished the parish church but the tower remained standing.
A monastic settlement was founded in Clondalkin by St. Mo-Chúa or St. Crónan in the late 6th or early 7th century. The road now splits the site in two, with a churchyard standing on the opposite side of the street to the tower. Still, the general layout make sense, with the doorway still facing a church. It’s not the original – perhaps the one that fell foul of the gunpowder explosion was on the site of that. There are two early crosses and a baptismal font in the churchyard, along with the remnants of the demolished church. You can see photos of those on the Ireland in Ruins blog. The evening of my flying visit, the churchyard was locked up.
Like many other old buildings in Dublin (i.e. Kilmainham Gaol, part of the old library in Trinity College, numerous Georgian houses), the tower is built from calp Limestone. The masonry is somewhat uneven and unlike most other towers, this one doesn’t narrow as it moves upwards. Indeed, the top of the tower flares out a bit.
At the bottom of the tower is a base which was added at a much later time. There is no date for this addition but it is thought it may have helped stabilise the tower. The base has some steps cut into it, which provide access to the door. The lintelled doorway and windows are much less elaborate than ones that are found elsewhere. The doorway is surrounded by granite.
According to Brian Lalor’s book, there are floors and ladders in the tower and that a key for access is available from the caretaker. It is unclear if that is still the case.
The tower is hard to miss, seeing as it is standing on the side of the road in Clondalkin. There is parking in the nearby shopping centre. Since my brief visit back in 2014, a visitor centre has been developed close to the tower (more info here). An excuse to revisit? 😉
