Located at Ardane at the eastern end of the Glen of Aherlow is St Berrihert's Well & Kyle. The principal feature of this site is the oval enclosure, the Kyle, as it is called locally which was created to preserve the unique collection of stones found on the site. These include the head and base of a large cross, fragments of quernstones, a detached stone with a bullaun with many inscribed and carved stones.
St Berrihert is celebrated locally on February 18th with local Mass and followed by rounds of personal prayer at the site. To the east of the Kyle is St Berrihert's Well, a strong spring of water forming a pond about 1.5m deep and 20m across. In the crystal clear water the spring can be seen bubbling up through the sandy bottom.
Local tradition has it that the water from this well cannot be boiled and that stones from the well will save you from fire.
