The Leeberg at Grossmugl in Lower Austria is the largest burial mound of the entire Hallstatt culture, standing approximately 14-15m high with a 55m diameter. Erected c. 600-500 BC by the Kalenderberg culture, a northeastern subgroup of the Hallstatt culture, it likely served as the burial place of a powerful ruler. The tumulus has never been excavated and this will not change in the foreseeable future. A smaller adjacent mound, the "Tomb of the Queen," investigated in the 1950s, yielded clay vessels with bull-head decorations and a rider-and-horse sculpture. Modern non-destructive surveys have documented an extensive Iron Age cult site and settlement landscape around the mound.
