Overview
The monastic settlement at Glendalough sits in a broad, glaciated valley within the Wicklow Mountains National Park. Founded in the 6th century, the site has evolved from a solitary hermitage into one of Ireland’s most significant early Christian communities. Today, it draws visitors for its compact collection of well-preserved ruins, the dramatic mountain and lake scenery, and the rare continuity of worship that continues in the nearby parish church.
History & Significance
Saint Kevin (Caoimhín) arrived in the valley around 540 AD, seeking isolation among the craggy hills and twin lakes. What began as a simple hermitage gradually attracted disciples, scholars, and pilgrims, growing into a major monastic centre that rivaled institutions like Clonmacnoise and Iona. The stone structures that remain today span several centuries of Irish history, reflecting shifts in religious practice, architectural style, and local devotion.
The site’s layout follows the natural topography. The earliest features cluster around the Upper Lake, where Kevin’s original sleeping grotto was adapted from a prehistoric rock shelter. As the community expanded, later monastic buildings were constructed using local granite, and the settlement eventually extended down the valley to Hollywood, where the parish church still stands.
What to See & Do
St Kevin’s Bed
Carved into the south shore of the Upper Lake, this one-metre-high cavity is the oldest feature on the site. Originally a natural rock shelter used in prehistoric times, it was later adopted by Saint Kevin for prayer and rest. The space is too small to enter comfortably, but standing outside offers a clear view of the lake and the steep cliffs that inspired the saint’s retreat.
The Wishing Cross
Standing near the main car park, this 3.35-metre-high monolithic granite cross dates between the 9th and 12th centuries. Unlike the intricately carved high crosses found at Monasterboice or Kells, this cross is deliberately simple, featuring only a single ring and a subtle lean. Local tradition holds that wrapping your arms around the cross and making a wish will ensure it comes true, a practice that has kept the stone smooth in places from centuries of visitor contact.
The Kitchen Chapel & Round Tower
The Kitchen is a 12th-century nave-and-chancel chapel built from carefully dressed granite blocks. Its name comes from a later folk tradition rather than its original function, and it should not be confused with the nearby Round Tower. The Round Tower stands independently on a rocky outcrop and retains its distinctive conical stone cap. Together, the chapel and tower form the architectural heart of the medieval monastic complex, with clear sightlines across the valley floor.
St Kevin’s Church (Hollywood)
A short walk from the ruins leads to Hollywood, where the parish church of St Kevin’s has served the local community since around 1680. The building is notable for its rare corbelled stone roof, which eliminates the need for wooden beams, and its original gas-lamp lighting fixtures. The church remains an active place of worship and marks the traditional starting point for the Camino de Glendalough, a modern pilgrim route that traces early Christian footpaths through the mountains.
Walking & Hiking
The monastic site is easily explored on foot, with well-maintained paths connecting the Bed, Cross, Kitchen, and Round Tower. For longer walks, the valley offers routes along both lakes and up into the surrounding forested hills. Sturdy footwear is recommended, as some sections are steep and uneven.

The monastic site works best when visited early in the day, when the morning light catches the granite ruins and the valley is quiet. Allow at least two hours to walk the full circuit, visit the Visitor Centre, and step inside the parish church in Hollywood. If you’re planning to combine the visit with a mountain walk, start from the car park and head toward the Round Tower first, then work your way back down to the lakes.
