The Hill of Tlachtga is associated with the Hill of Ward in County Meath, and its celebrations rivaled those at Tailtiu. The major ceremony held at Tlachtga was the lighting of the winter fires at Samhain (November 1). The ringfort built on the hill was associated not only with the kings of Mide, but also with Munster as well. The site was known in the popular culture of medieval Ireland as a place where Mug Ruith's flying machine roth rámach had been seen, and where the ard rí Ruaidrí Ua Conchobair had held a massive assemblage in 1168.
