Williamstown Harbour lies on the West shores of Lough Derg. It is not really large enough to be a town but is a substantial village and is situated half way between Dunmore and Ballymore in North Galway. Few other places will boast of such a strange beginning because it was founded in the last century by William McDermott, a local landlord, just to spite a rival who tried to establish another town close by! All is quiet in Williamstown now, as the era of the landlord is long over, and the other town failed to survive.
There is a reference to the White House Inn which lies at the top of the village. However this was not visited on our travels. (How unusual)
