In 1959, remains of an urnfield dating from the Late Bronze Age and Early Iron Age were found on land near De Kamp farm on Lichtenvoordsestraatweg in Barlo. In 2003, the urnfield was designated a national monument.
The Arnhemsche Courant reported on 11 March 1959:
“Yesterday, during excavation work at the farm of farmer A.J. te Paske, De Kamp in Barloo, municipality of Aalten, a number of urns were found. During the morning hours, the first urn was discovered at a depth of approximately 40 to 50 centimetres; it was still virtually undamaged and contained skeletal remains.
Mayor E.S. van Veen was informed of the discovery immediately, after which municipal workers continued the excavation. Over the course of the day, four more urns were uncovered within an area of just a few square metres. Several years earlier, urns had also been found about a hundred metres from this site.
