Croom

Croom is a village in County Limerick, Ireland. It is located just off the N20 on the River Maigue. It is 8 km southeast of Adare on the N20.

Cromadh was a village in the territory of the Uí Fidgenti, and one of the seats of the O’Donovans of the Ui Fidgheinte, which flourished from the late 4th century to the mid 12th century. A hermitage, Dísert Óengusa, was founded nearby by Óengus of Tallaght around the year AD 780. The townland is located on the River Maigue, which although now having a tidal flow only to Adare, in ancient years the river had a tidal flow past Croom, making it a transit route for the Viking ships traversing inland from the Shannon during the 9th and 10th centuries. Contacts arising along the Maigue River between Danish Vikings and the Ui Donnabhains provide an insight into the alliance between the two groups in the late 10th century.
