2. Stone Forts

Ancient Irish stone forts: Iron Age and early Christian defensive structures

Stone forts are among the most significant ancient structures in Ireland, representing various types of architectural styles from the Iron Age to early Christian periods.

These structures served as defensive settlements and were built using locally sourced materials, demonstrating the ingenuity of ancient builders. Two primary forms of stone forts include Brochs and cashels, each with distinct features and historical contexts.

Brochs

Brochs in Ireland: Ancient stone towers

Brochs: Towers with double walls, circular layout, central courtyard, and cavity walls.

Brochs are impressive towers found mainly in Scotland but also appear in parts of Ireland. Dating from around 500 BCE to 200 CE, they feature thick, drystone walls that can reach heights of up to 12 meters.

Constructed with a double wall system, they often had a circular layout with a central courtyard. The walls’ cavity construction allowed for additional living space and insulation. Brochs served as elite residences, indicating the social status of their occupants. Their architectural sophistication influenced later Irish designs, reflecting the rich cultural heritage of ancient Irish architecture.

Cashel

Cashels, or stone forts, are primarily found in Ireland and are linked to the Iron Age and early Medieval periods. These circular structures were constructed mainly from local stone and typically feature thick walls up to 3 meters (10 feet) high.

Unlike brochs, cashels were used as communal living spaces and were often surrounded by a defensive ditch or external wall for protection.

Many examples of cashels have been well-preserved. The architectural style of Cashels reflects the vernacular architecture of the time, highlighting the connection between the landscape and building practices in ancient Ireland.

Early Christian architecture in Ireland represents a blend of local building traditions and continental influences. This period is marked by distinctive architectural features such as round towers and various monastic buildings, which played a significant role in the evolution of Irish architecture.

Round Towers

Round towers are a distinctive feature of early Christian architecture in Ireland, serving both religious and practical purposes. Constructed primarily from local stone, these towers typically stand between 20 and 30 meters (65 to 98 feet) tall and are topped with a conical roof.

They were used for various functions, including as belfries, storage for valuable items, and places of refuge during attacks.

Notable examples include the towers at Glendalough in County Wicklow and Kildare in County Kildare. Their robust design showcases sophisticated masonry techniques and the effective use of local materials. The round tower’s architectural style reflects a fusion of ancient traditions and early Christian practices, becoming a prominent feature in the Irish landscape.

The use of local limestone and sandstone was prevalent, demonstrating the adaptation of available resources.

Key structures, such as the beehive huts on Skellig Michael, exemplify innovation in design and construction. These huts, with their corbelled roofs, were constructed to withstand harsh weather conditions and blend harmoniously with the rugged landscape.
