One of the six cathedrals of the Anglican Bishop of Cashel and Ossory, who currently resides in Kilkenny, is located in the town. It is in the civil parish of St. Patricksrock which is in the historical barony of Middle Third.

The Heritage Centre & Tourist Office on Main Street displays a model of Cashel in the 1640s and a multimedia presentation in several languages, and sells Tipperary crafts. The charters granted by kings Charles II (1663) and James II (1687) are on display in the Heritage Centre.

The former Church of Ireland Archbishop's palace which is now being restored to be a leading hotel off Main Street.

St. Dominic's Abbey's ruins are visible southeast of the Rock.

The Cashel Folk Village includes replica displays of country life in early Ireland, including an old public house, a butcher's shop, a farmhouse, a Traveller's caravan, and a chapel. It also includes republican monuments commemorating Tipperary's role in the Anglo-Irish War and Irish Civil War.
