Overview
Old Leighlin (Irish: Seanleithghlinn) is a tiny village, civil parish and townland in County Carlow, situated about 12 km south of Carlow town and just west of Leighlinbridge. Though modest in size, it boasts a remarkable ecclesiastical heritage centred on St Laserian’s Cathedral and the adjoining holy well of Tobar Molaise. The cathedral, one of Ireland’s smallest medieval cathedrals, remains an active Church of Ireland parish and a key stop on the County Carlow “Trail of the Saints”.
History / Background
The site’s story begins in the early 7th century when Saint Gobban founded a wooden monastic settlement on the banks of the River Barrow. His brother, Saint Laisrén (later known as Laserian), succeeded him and, in AD 630, convened a synod that adopted the Roman method for calculating Easter – a decision that aligned the Irish church with continental practice and still shapes the liturgical calendar today.
Around 1060 the original wooden monastery was destroyed by fire. Reconstruction under Bishop Donatus (c.1152‑1181) gave rise to the stone cathedral that still dominates the landscape. The 13th‑century nave and choir were completed by the end of that century, while the 15th‑century added a massive central tower and a Lady Chapel. Later alterations include 16th‑century work by Bishop Matthew Sanders and 19th‑century restorations that saved the building from collapse. Archaeological surveys in the early 2000s uncovered 44 surrounding structures dating from the 5th to the 15th centuries, confirming Old Leighlin’s long‑term prominence.
What to See & Do
- St Laserian’s Cathedral – The nave stretches only 82 ft and the tower rises 59 ft, yet the interior is packed with quirks:
- Four‑bay (four‑tiered) sedilia – a rare staggered set of stone seats, each higher than the next, offering a glimpse of medieval episcopal hierarchy.
- Window paradox – the nave is completely windowless, while the chancel boasts an elegant 13th‑century lancet window partially obscured by a later 17th‑century buttress.
- Catherine O’Brien East Window – a masterpiece of the “A‑Tur Gloine” movement, depicting seventeen Irish saints, including St Laserian.
- Ancient fonts – two fonts survive, the older dating to the 11th century, among the oldest liturgical objects still in use in Carlow.
- Underground passage – a mysterious tunnel beneath the floor whose purpose remains debated; it is highlighted on guided tours.
- Lady Chapel – recently restored, providing a surprisingly spacious sanctuary within the compact structure.
- Surrounding Holy Sites – A short walk leads to the 7th‑century Cross of Saint Laserian and the holy well (Tobar Molaise), still visited by pilgrims who leave offerings.
- Guided Tours – During the summer months the Leighlin Union of Parishes runs docent‑led tours (typically 12:00‑16:00 on selected dates) that explore the cathedral’s architecture, cryptic passageways and local lore, including Viking raids and a World‑War II pilot’s brief stay.
