Macosquin Abbey, formally known as Clarus Fons, was a Cistercian Monastery in County Londonderry, Northern Ireland in the United Kingdom.
[1][2] The Monastery was located on Abbey Lane, Macosquin, Northern Ireland.
[4] There may have been a monastic establishment in Macosquin as early as the 6th century, however, the Cistercian Abbey of Our Lady of the Clear Springs was founded in 1217 by monks from the monastery of Morimond, a daughter house of Citeaux in France.
The Abbey site was occupied at the beginning of the 17th century by a plantation of the London Guild of Merchant Taylors.
[6] The last remains of the Abbey buildings were removed in the 18th century and the Protestant Church of Saint Mary probably occupies the Abbeys site and may have reused the foundations.
