Tumuli of Libersart, Archaeological burial mounds in Tourinnes-Saint-Lambert, Belgium.

The Tumuli of Libersart are two ancient burial mounds located near Walhain in Belgium. The western mound rises to about 4.5 meters in height, while the eastern one reaches roughly 6.2 meters, with each situated in different surroundings: one set within woodland and the other across cultivated fields.

The two mounds are Gallo-Roman tombs linked to a vicus that existed at Tourinnes-Saint-Lambert in the 2nd and 3rd centuries AD, beside the Bavay-Tongeren-Cologne road known as the chaussée Brunehaut. Excavations in 1910 and 1911 by the Société Archéologique de Bruxelles found nothing except traces of a wooden post at the centre of the western mound, probably because the graves had been looted over time. The mounds were listed as monuments on 5 April 1972 and as exceptional heritage of Wallonia on 7 February 2013.

These burial mounds represent one of fifty identified tumuli in the Hesbaye region, spanning across Walloon Brabant, southern Limburg, Liege, and northern Namur provinces.

The two mounds lie about 100 metres apart, 500 metres north-east of Libersart's centre, at a high spot where five paths meet. The eastern mound stands between Rue des Tumuli and Rue de Libersart; the western one sits between the two arms of the path called Chapelle Daix, hidden in a small wood. The surrounding land is protected as a site.

The two mounds stand at a high spot called "La Tombe" or "Les Tombes", at the crossing of five paths, about 500 metres north-east of Libersart's centre. The eastern mound, between the Rue des Tumuli and the Rue de Libersart, is the taller at 7 to 8 metres with a base circumference of about 60 metres.
