This quaint little village, nestled at the foot of the Knockmealdown Mountains, is situated eight miles from Clonmel on the banks of the river Suir, and at the foot of the majestic Knockmealdown Mountains. A former ‘Breac’ Gaeltacht (Irish speaking) area, Newcastle still holds on to its Irish-speaking traditions and hosts a number of festivals and summer schools to help promote the Irish language.
The village has many amenities close by and it is the starting (or finishing) point for the Knockmealdown linear trails that meanders 28 kilometres through the mountain lowlands to Ballyporeen. Part of this trail, close to the village itself, is the monument to General Liam Lynch who was shot during the Irish civil war. This shooting is regarded by many as one of the final shots of that war and, as such, the monument marks more than just the place where the shooting took place.
