Moel y Gaer (Welsh for "bald hill of the fortress") is an Iron Age hillfort located on a summit at the southern end of Halkyn Mountain, overlooking the village of Rhosesmor, Flintshire, Wales. It is a well-preserved hillfort overlooking the Dee Estuary. Excavations in the early 1970s revealed a sequence of defensive structures made of timber and several phases of building work inside the ramparts. Excavations suggest that the site was occupied, perhaps sporadically, from the Neolithic period to sometime before the Roman conquest of the area. Remains of a timber long house on the hill summit have been dated to the third millennium BC and may represent the earliest human occupation of the region. Defensive construction at the site began around the late seventh century BC, and at first consisted of a timber palisade enclosing a settlement of timber roundhouses. The palisade was later replaced by a stone-and-earth rampart and a ditch.
