According to written sources, Glendalough Monastic Site was founded by St Kevin, a 6th-century monk who led a hermit’s life in the isolated Wicklow Mountains.

The hermit dedicated his life to Christianity, a new faith in an ancient Celtic culture. He is believed to have settled in a remote cave by the Glendalough Upper Lake, where he could live the austere life that his faith demanded.

As a former Christian settlement, the Glendalough archaeological site includes a Cathedral, St Kevin’s Church, and the ancient St Kieran’s Church, of which only the foundation has been preserved. Glendalough is unique in Ireland, and the monastic settlement is considered one of the best-preserved in the country.

The oldest ruins of the Monastic Site thus date back to St Kevin’s time, but most of the current ruins are not quite so old. The Glendalough Cathedral was built in the 10th and 11th centuries – and has partly been restored in the 19th century to preserve the architecture and cultural heritage of Ireland’s past in the Wicklow Mountains.

Today, the ruins bear witness to the place’s former function and its heyday when it was a symbol of a new religious era. In addition to being a sanctuary, Glendalough Monastery was a sacred place where the monastery residents could devote themselves to writing, poetry, teaching, traditional crafts, and agricultural practices in Eastern Ireland. Not surprisingly, a small religious community emerged here in the middle of what is now the Wicklow Mountains National Park. The evidence is the large number of headstones scattered around the small church.

Coming from the Visitor Centre, the arched Gateway marks the main entrance to the monastic site. Continuing into the graveyard, hundreds of Celtic crosses emerge as visible proof of the religious significance Glendalough had a thousand years ago. Celtic crosses are Christian crosses with a ring, an Early Middle Age feature in Irish Christianity. They exist in three variants: plain crosses, as here at Glendalough, abstract ornamental crosses, and carved scriptural crosses. Often, the Celtic Cross is interpreted as Christ conquering death!

Graves and headstones still stand in the cemetery as they have done for centuries.

No visitor can be in doubt that Glendalough’s landmark is the 30-metre-high Round Tower, which can be seen from afar. However, there has been much speculation about its former function. Guesses range from the solid tower with 1-metre-thick walls being a simple bell tower to serving as a secure hiding place in case of an invasion by hostile people. The latter would also explain why the entrance door has been elevated from ground level. A ladder, which could be removed if desired, was thus required to enter.

Also, in a direct line from the Gateway, the ancient Cathedral, dedicated to St Peter and St Paul and probably built in the 10th and 11th centuries, impresses visitors with its solidity and details. Most likely, it was once the centre of Monastic City, where the monks gathered for prayer.
In addition to St Kevin’s Cross and hundreds of other Celtic crosses, the ruins of the Priests’ House still exist. The Priests’ House is believed to have housed the dead priests as a resting place!

One of the highlights is St Kevin’s Church, a picturesque stone church with a rustic stone roof and an integrated round tower! The tower is accessed from the church roof. St Kevin’s Church dates to the 10th century and is the perfect photo spot at Glendalough!

Afterwards, continue to the lakeside for spectacular views of the surrounding mountains and trees reflected in the lake mirror on a calm day. The name Glendalough originates from Gleann Da Loch (meaning ‘valley of the two lakes’ – the Glendalough Upper Lake and Lower Lake).

The nearest lake is the Lower Lake, a breathtaking small lake surrounded by forested hillsides.

The larger Upper Lake is equally beautiful, with numerous secret spots along the lake. One location to look for is St Kevin’s Bed, a natural cave above the Upper Lake, a pilgrimage site today. According to the legend, this was what St Kevin used as a retreat where he could ponder and pray.
