The truncated remains of Causetown Castle, County Meath. Otherwise known as Lisclogher, this late-mediaeval tower house is believed to have been built for the Dowdall family, settled in the area since the arrival of the Anglo-Normans.

The building has curved angles on two sides and a pair of circular towers on the other pair, that to the south-east, which contained garderobe closets, being in better condition and rising three storeys, as no doubt once did the whole castle. However, at some date the upper portion was lost so that now the interior contains little other than a ground floor barrel-vaulted chamber.
