In addition to Athlumney Castle in County Meath, there is Dowdall's Castle in Dundalk, but all that remains of it is a business and a plaque on the side of the building that indicates that it was once Dowdall's Castle. There is Glaspistol outside of Termonfeckin which also belonged to the Dowdall family, as well as Monkstown, County Meath and Causetown, County Meath. All are approximately 30 miles from Dublin. Could you give more details of what you are searching for? Specifically a castle called Dowdall's castle or castle which once belonged to the Dowdall family? There are also other homes which still the ruins still exist which belonged to the Dowdall family.
