About 1/4 mile due E from Langold are several holes in the ground, in which large trees are grown up. The place is spoken of as the site of a village which was called Costhorp. In inquisitions as Catesthorpe, Odesthorp or Odethorp - 17th Ed II (1324) and 46th Ed II (1354 and 1373). (1)
The approx site of this deserted village is probably indicated by the existing names of Costhorpe Farm and Plantation but much of the area is now covered by the Firbeck Main Colliery. The remainder of Costhorpe Plantation falls within 2 dry artificial lakes, presumably the "holes" referred to above. No evidence of the former village was seen during field work, nothing visible on APs. (2)
