uring archaeological research on the east side of Haarlems' sand barrier features from the Neolithicum and the Early Bronze Age were found.

Two field layers divided by eolic sand were found. In these field layers clear marks of an ard were found together with Bell beaker sherds and little pieces of charcoal.
In the field layers also ditches and pits were observed among were some post holes. The number of post holes was too small for the reconstruction of a house.

Most of the pottery found was typical Bell beaker, only some were Wikkeldraad.
Also flint was found: various scrapers and many flakes. Remarkable was a ± 2,5 cm. long arrowhead.
Pottery and flint tools were made on the spot.
