St. Joseph's C.B.S. Nenagh is located on an elevated site in Summerhill, Nenagh, Co. Tipperary, Ireland. Students in the school not only come from Nenagh town but from towns and villages within a radius of ten miles. Nenagh derives its name from Aonach Urmhumhan meaning fair of Ormonde. It is the chief town of North Tipperary.

Situated in a fertile plain surrounded by the Silvermine and Arra mountains. Nenagh castle is one of the finest of its kind in Ireland, it was built by Theobald FitzWalter one of the ancestors of the Butlers' of Ormonde, in 1200. It is a hundred feet high and at its base 53 feet across.

In 1860 the top portion was reconstructed. The Parish church of St. Marys' of the rosary is a large Gothic revival building. Opposite is Nenagh Heritage Centre which contains a display of antiquities in the heptagonal Governors house. Nenagh has many amenities to offer, many of which are close to the school. For instance, just across the road from our school is a fully equipped gym and a swimming pool. A large shopping centre and coffee shops are also near by.
