Oldcastle is a small town in County Meath in Leinster, Ireland, known as a gateway to nearby prehistoric sites and the surrounding drumlin countryside. In town, Oldcastle Main Street forms a compact center with cafés, shops, and traditional Irish pubs, and there are quiet walks and fishing spots along the River Inny.
The headline historic draw is Loughcrew, a Neolithic passage tomb complex with hilltop cairns, and the nearby Loughcrew visitor gardens add a visitor center and gardens that explain local archaeology and flora. For more medieval heritage in the wider area, the Abbey of Kells offers monastic ruins and famed high crosses, while Trim Castle is a large Anglo-Norman castle overlooking the River Boyne. Nature trips often focus on nearby lakes such as Lough Owel, a spring-fed lake in County Westmeath, and Lough Ramor, a scenic lake near Virginia, County Cavan.
