I’ve been intermittently pursuing a minor historical mystery since visiting the Narrow Water Castle in Warrenpoint, Co. Down last summer. Across the river (as you can see from the photo at the top) a rather cool-looking round tower was peeking out of the woods, shadowed by a mini-tower on the muddy river bank (far left of the photo). The Narrow Water Castle is a pretty awesome place: they have a murder hole, a garderobe (medieval toilet — guaranteed to fascinate the elementary school set), and a gorgeous setting where the Newry river enters Carlingford Lough and then forms the Irish Sea, so I didn’t really think about much the round tower except as backdrop. Later I thought I should find out some more about that tower.
There’s a good website for tower spotters, roundtowers.org, that lists all the round towers in Ireland — at least the surviving ones — but I couldn’t find a tower listed in that part of Co. Louth. No problem, there are other resources, but again nothing listed this tower. I checked Google Earth, just to make sure I wasn’t mis-remembering the location. I Googled “round tower” with the name of every townland in the area, but found nothing except a couple of photos of “a round tower near Omeath” (the nearest village) on Flickr. So I appeared to have a round tower that nobody, except a few photographers, seemed to care about.
Finally, the “mini round tower” down by the river gave me a clue. Who builds a miniature round tower at the edge of a river in the shadow of a real one? Why build such a thing? Well, presumably as a marker for shipping, right? Then I found a different view of the mini tower and saw a solar panel hanging off the front. Then it clicked into place: this is a pair of lighthouses built to look like ancient round towers — one 16 feet tall and one 49 feet.
As we’re living in the internet age, there’s a lighthouse spotters database (actually a couple of them) where I learned these are the two “Newry River Range” Lighthouses, solar-powered channel markers built in the shape of round towers. It turns out there was a trend for building lighthouses to look like round towers in the late 19th century. Who knew? So there you have it: When is a round tower not a round tower? When it’s a lighthouse.
