A friend who lives nearby these burial mounds sent me photos of them and they are posted now this page now. Here is a translation of the Dutch Language Wikipedia site entry for these mounds:
The Heike grave field is a grave field in which at least 27 graves have been found, located at Klein-Ravels in the Ravels municipality in the Belgian province of Antwerp.
This cemetery was used in the period from the late Bronze Age to the early Iron Age (1100 - 475/450 BC). In accordance with the usual burial rituals in the Kempen, the dead were cremated here, after which the remains were buried in a burial mound or flat grave in an earthenware pot. Rarely, additional information was provided. The urns present were from the Harpstedt pottery, which is typical of the early Iron Age. One also found one smaller bee-jar, an egg-ercher.
The burial mounds had a diameter of five to six meters. Some of the flat graves had an encircled structure in the form of a ring-shaped ditch or a pile wreath. The burial ground with the 27 burial monuments involved 16 burial mounds and 11 flat graves. Of the burial mounds, three were noted without a border structure, 10 with a ring ditch and 3 with a dense wreath of poles. Of the flat graves 5 had a small ring ditch and 6 had no edge structure.
In 1984-1985, archaeological research was carried out by the National Excavation Service, now called the Flemish Institute for Immovable Heritage.
There are now 12 restored burial mounds.
