Place & story
The monastic settlement and Easter
The cathedral occupies the site of an early medieval monastery associated with Saint Gobban and Saint Laserian. Leighlin Parish’s account identifies the synod held here around 630 with the adoption of the Roman method of calculating Easter. The gathering places Oldleighlin within a wider debate about church practice, long before the surviving stone cathedral took shape. [2]
A building changed over centuries
The cathedral’s fabric reflects repeated additions and alterations. Its nave has windowless side walls, while later openings, blocked arches and buttresses record changes elsewhere in the building. Restoration in 2014 installed solar heating to help address persistent damp. The medieval church has therefore continued to acquire practical adaptations as well as monuments. [3]
Catherine O’Brien’s east window
Catherine O’Brien created the cathedral’s east window in the mid-1930s as a memorial to Mary Louisa Vigors, commissioned by her son Edward Cliffe Vigors. Its figures bring together Patrick and Brigid, local saints including Laserian and Moling, and the apostles John and Paul. The window connects a family commemoration with an ambitious twentieth-century work of stained glass. [3]
The procession to the well
The cathedral’s visitor guide records a shared feast-day observance on 18 April, when Church of Ireland and Roman Catholic worshippers process from the cathedral to Saint Laserian’s Well. Also known as Saint Molaise’s Well, it remains a place where visitors leave mementoes and tie cloth to a nearby tree. The account documents continuing devotional practice around the village’s patron saint. [3]
