Tuam, Co. Galway
Tuam (Irish: Tuaim) is a small town in County Galway. Tuam gets its name from the Tumulus - a bronze age burial ground - on which the town is built. It was established in the 5th century when St Jarlath founded a monastery here, stopping when a wheel broke on his chariot.
The O'Connor Kings, Turlough and Ruari, lived here In the 11th century. Turlough built a castle and an abbey which later became a cathedral. All that remains is part of the wall of their castle, a stone throne known as the chair of Tuam, and the O'Connor name.
The people of Tuam claim it is the smallest city in the world based on the presence of a cathedral, one of the original definitions of what constitutes a city. However, despite Tuam's two cathedrals, it is officially a town. Moreover, the city of St. David's in Wales has a smaller population and is officially a city.
