The ruins of Oola Castle stand close to the village and in 1825, some large and perfect antlers of the Irish elk were discovered; and, in 1828, a brazen trumpet, and spear and arrowheads of bronze were found, which were placed in the museum of Trinity College, Dublin.[3]
Transport
The main N24 road from Limerick to Waterford passes through the town, with the town of Tipperary lying 12 kilometres south-east of Oola.
Though the town is no longer connected to the rail network, the important station at Limerick Junction is nearby, 5 km to the south-east. Oola railway station opened on 9 May 1848 and finally closed on 9 September 1963.[4]
Oola is on Bus Éireann's "Expressway" route no. 55 which runs between Limerick and Waterford several times a day.[5]
