Hidden 4,000-Year-Old Stone Circle Uncovered Beneath Fields Near Belfast

An undiscovered stone circle, estimated to be over 4,000 years old, has emerged from beneath fields close to Belfast. This find adds a significant element to one of Northern Ireland’s most extensive ancient ritual areas. The reveal followed the identification of cropmarks through aerial imagery, which hinted at structures concealed underground.

The dig is located within the Ballynahatty Ritual Complex, a region known for about 50 archaeological sites. Managed by Queen’s University Belfast, this initiative integrates archaeologists, local volunteers, and school students to explore the site's unexpected scale indicated by the aerial survey.

Experts have determined that the cropmarks represent a Late Neolithic or Early Bronze Age stone circle. The excavation is part of the Community Archaeology Programme Northern Ireland (CAPNI) and is supported by the National Lottery Heritage Fund.

Aerial Images Illuminate Buried Secrets

The identification came from detailed analysis of aerial photos, which revealed a pattern of cropmarks surpassing the previously documented remains. This suggested that the Ballynahatty Ritual Complex extended beyond what was known.

Brian Sloan, from Queen’s University Belfast’s School of Natural and Built Environment, explained that the images prompted further investigation of the field. Excavations soon verified the existence of a prehistoric stone circle underground.

Sloan also referenced prior digs by Barrie Hartwell in the 1990s, which unearthed the so-called “Neolithic Temple” at the Giant’s Ring. This included a large timber circle featuring an internal platform thought to be used for excarnation.

“We came across aerial photography of the area and noticed a number of crop marks in the field, which suggested the Ballynahatty Ritual Complex extended further than we first thought.” He said. “We decided to dig deeper and work with community volunteers and schoolchildren to try to piece together the area’s hidden history.”

Tracing the Origins of an Ancient Monument

Findings indicate the structure dates from the Late Neolithic or Early Bronze Age, with no current signs of burial use.

Queen’s University Belfast states that the site is part of the larger Ballynahatty Ritual Complex situated at the southern tip of the Malone Ridge. Sloan explained that much of the circle suffered damage during the 1800s when agricultural activities led to the dismantling of ancient monuments.

Stone circles continue to puzzle researchers. Sloan noted that although their construction demanded significant labor, their exact purpose remains the subject of ongoing debate.

“The function of stone circles remains a bit of a mystery. A great deal of effort is required to construct them, but what they were actually used for is open to debate. There is a chance that they were used for religious ceremonies, gathering at certain times of the year,” he explained.

Sloan highlighted that other locations, such as Beaghmore in County Tyrone, exhibit astronomical alignments possibly intended as a prehistoric calendar system.

Community Effort Unearths Ancient Site

The dig has actively involved community volunteers and children from local schools for several weeks, allowing residents to engage directly with the archaeology. Despite challenging weather, from heavy rain to intense heat, participants remained committed to uncovering the site's secrets.

“It has been fantastic to work alongside community volunteers and schoolchildren to try to piece together the history that lies beneath us. They have battled both heavy rain and scorching sunshine over the last few weeks, and we’re delighted with what they’ve helped uncover,” Sloan said.

A memorable moment occurred when Harper, a student at Finaghy Primary School, found a damaged arrowhead during the excavation. The investigation continues as experts explore how this newly discovered circle fits within Belfast’s broader prehistoric environment.
