Cnoc na dTobar is noted as an ancient pilgrim mountain. Even before Christian times, in the 5th-century, the Knocknadobar was a place of celebrations for Celtic Lúghnasa Festivals in August. Lúgh (pronounced Loo) was the god of the Harvest, and festivals or dancing and merriment were held on high ground to make offerings for a good harvest, and Knocknatobar's wide flat summit provided a suitable venue. The word for August in the Irish language is Lúhgnasa (pronounced in English as Luanasa). In 1884-85, Christian crosses were placed along on the ancient pilgrim trail to represent the 14 stations of the cross, and an altar and a large Celtic cross was placed at the top where mass is said yearly; these works were undertaken by Canon Brosnan of Cahersiveen.
