    History of Glendalough

    Follow the city from Roman Londinium to its modern global identity through landmark moments that still shape the visitor experience.

    The Founding of Glendalough

    Glendalough, often referred to as 'The Valley of the Two Lakes', was founded in the 6th century by St. Kevin, who sought solitude in this remote and picturesque valley. St. Kevin established a monastic settlement that attracted monks and ascetics, becoming one of the most important ecclesiastical centers in Ireland.

    Monastic Settlement and Growth

    Throughout the 8th and 9th centuries, the monastic community at Glendalough expanded. It became a renowned center for learning and pilgrimage, drawing scholars and visitors from across Ireland and beyond. The settlement included a round tower, several churches, and other monastic buildings, many of which still stand today.

    Viking Raids

    Like many other Irish monastic sites, Glendalough was not immune to Viking raids. The settlement was attacked multiple times in the 9th and 10th centuries. These raids caused significant destruction but did not extinguish the monastic community's spirit or its importance.

    The Battle of Glen Mama

    In 999 AD, the Battle of Glen Mama took place near Glendalough. This battle was a decisive victory for the High King of Ireland, Brian Boru, against the forces of the Kingdom of Leinster and the Dublin Norse. This victory helped to secure Brian Boru's dominance in Ireland.

    Medieval Pilgrimage Site

    During the medieval period, Glendalough became one of Ireland's most important pilgrimage sites. Pilgrims would travel from far and wide to visit the relics of St. Kevin and the holy sites within the valley. The 'Pattern of St. Kevin' was a significant pilgrimage route that included various stations of prayer and reflection.

    The Decline of the Monastic Settlement

    By the late 12th century, the political and ecclesiastical landscape of Ireland began to change. The arrival of the Normans and subsequent reforms led to the decline of the traditional monastic settlements. Glendalough's community gradually diminished, and by the 17th century, it had fallen into ruin.

    19th Century Restoration

    In the 19th century, interest in Ireland's medieval heritage led to the restoration of several sites within Glendalough. Efforts were made to preserve the round tower, St. Kevin's Church, and other significant structures. This period marked the beginning of Glendalough's transformation into a heritage and tourism site.

    Modern Day Glendalough

    Today, Glendalough is a major tourist destination, attracting visitors from around the world. The site is managed by the Office of Public Works, and it offers a combination of historical exploration and natural beauty. Visitors can explore the monastic ruins, walk the trails around the two lakes, and immerse themselves in the serene landscape that once attracted St. Kevin.
