Located toward the top of a north-facing slope with commanding views across the Waterford coastline, this exceptional 12th-century round tower at Ardmore stands as one of Ireland’s most architecturally sophisticated and well-preserved examples. Rising approximately 29 meters with distinctive external recessing and elaborate carved decoration, the tower demonstrates the pinnacle of Irish round tower craftsmanship while raising intriguing questions about its relationship to the adjacent cathedral.

Unusual Positioning and Dating Implications

The tower’s location “S of the Cathedral, the principal church within the graveyard, rather than to the SW” represents an unusual arrangement that has important archaeological implications. This positioning leads O’Keeffe to suggest “that the tower may predate the cathedral and relate to a now missing church,” indicating the site may have had a more complex developmental history than initially apparent.
This theory suggests Ardmore’s round tower was originally built to serve an earlier church that was subsequently replaced by the present cathedral, with the tower’s position preserved even as the ecclesiastical complex was reconfigured. Such architectural continuity would demonstrate the reverence medieval builders held for existing round towers even when constructing new religious buildings.

Sophisticated 12th-Century Architecture

The tower demonstrates exceptional medieval craftsmanship, measuring 5 meters diameter at the base and featuring “a cut-stone plinth” that provides formal architectural emphasis. The structure contains four floors with a distinctive design feature: “the upper three floors are recessed externally with a string course (diam. at top 3.05m).”

This external recessing creates a visually striking profile where the tower narrows as it rises, emphasized by horizontal string courses that mark the floor divisions. This sophisticated architectural treatment is relatively uncommon among Irish round towers and indicates the builders possessed advanced design capabilities and aesthetic sensibilities.

Elaborate Decorated Doorway

The round-arched doorway, positioned approximately 4 meters above ground level, showcases exceptional decorative stonework. Measuring about 1.76 meters high and 70 centimeters wide at the base, the entrance is “decorated by a continuous roll-moulding” that demonstrates sophisticated 12th-century carving techniques.

This decorative treatment places Ardmore within the tradition of Irish Romanesque architecture, where round towers incorporated continental European decorative influences while maintaining their distinctively Irish structural forms.

Carved Corbel Decoration

The tower’s interior contains remarkable decorative elements: “sixteen corbels to support wooden floors, five of which are carved with grotesque faces.” This sculptural program represents one of the most extensive decorative schemes found in any Irish round tower interior, demonstrating the builders’ commitment to creating both functional and artistic architecture.

The grotesque faces carved on the corbels reflect medieval artistic traditions found in Romanesque churches across Europe, indicating Ardmore’s builders were familiar with international sculptural conventions and possessed the skills to execute sophisticated carved decoration.

Window Arrangement and Modern Cross

The fenestration system includes “three small lights” at various levels and “four windows, one at each of the cardinal points of the compass, beneath the cap.” This arrangement provided optimal lighting and sound transmission while following traditional round tower design principles.

The cap is “surmounted by a modern cross,” indicating continued recognition of the tower’s Christian significance and ongoing maintenance of its religious symbolism.

Conservation History and Archaeological Discoveries

The tower underwent conservation in the 1840s by Mr. Odell, a local landowner, during which “a truncated inhumation was discovered inside the tower.” This burial evidence suggests the tower may have been used for high-status interments or that it was built over an earlier cemetery area.
“The original capstone is now inside the N doorway of the Cathedral,” indicating preservation of this important architectural element even when removed from its original position. This relocation demonstrates awareness of the capstone’s historical and artistic value.

1996 Archaeological Investigation

Excavation in 1996 “revealed a solid base of stone beneath the plinth and some recent burials,” providing evidence of the tower’s substantial foundation system and continued use of the site for burial purposes. The solid stone base indicates the medieval builders created exceptionally stable foundations appropriate for supporting the tower’s impressive height.

Recent Conservation

The notation that “the tower was recently reconserved” indicates ongoing professional maintenance that ensures the structure’s preservation for future generations. This conservation work is particularly important given the tower’s exceptional decorative elements and architectural significance.

Architectural and Historical Significance

Ardmore’s round tower represents one of Ireland’s finest examples of 12th-century ecclesiastical architecture, combining sophisticated construction techniques with elaborate decorative programs. The external recessing, carved corbels, and decorated doorway demonstrate the high level of artistic achievement possible within the round tower building tradition.

The tower’s unusual positioning relative to the cathedral, combined with the archaeological evidence of earlier activity, suggests a complex site development that may illuminate how Irish ecclesiastical complexes evolved over multiple centuries of continuous use.
