Just outside Armagh is Ulster's Camelot—the region's ancient capital. Excavations date activity to 700 BC. The fort has strong associations with figures of Irish history. Legend has it that thousands of years ago this was the site of the palace of Queen Macha; subsequent tales call it the barracks of the legendary Ulster warrior Cuchulainn and his Red Branch Knights. Remains dating from 94 BC are particularly intriguing: a great conical structure, 120 feet in diameter, was formed from five concentric circles made of 275 wooden posts, with a 276th, about 12 yards high, situated in the center. In a ritual whose meaning is not known, it was filled with brushwood and set on fire. Young children can dig into the past in the Archeo Pit, dress up as a Celt, and touch history with "feely boxes." In the summer guided tours are held every two hours and last 40 minutes. Ecology trails, opened in 2014, bring the environmental aspects of Navan to life. There's a bug hotel, listening posts, bird boxes, a viewing hide, and Armagh's only "bug and beastie" viewer. An Eco Warrier shows the children around and introduces them to the hidden life found in crevices, stones, and hedges.
