univallate hillfort

univallate hillfort [MC].
A defended enclosure common in the later Bronze Age and Iron Age of northwest Europe which is bounded by a single line of ramparts. Some strengthening may be visible around the entrance by the construction of outworks or an out-turned bank to create an entrance passage in front of the main gate. Early univallate hillforts often have timber-laced or box-framed banks to provide a strong but substantial inner element to the defences.
