A magnetometry survey was conducted on land at Churchill Avenue, Horncastle, to inform the proposed construction of a residential development. An extensive system of ditched enclosures and trackways was encountered, with concentrations in the north of the site. Many of the enclosures contained anomalies representing pit-like features or sites of burning such as hearths, ovens, kilns or furnaces. {1}{2} Subsequent trial trenching (see ELI14463) revealed that the enclosure complex was in fact no less concentrated in the south of the site. The geophysical survey also did not pick up on a trackway visible as a cropmark heading south past the site boundary.
