The Ancaster House site lies immediately to the south of the village of Ancaster on the eastern side of Ermine Street. To the north of the site is a scheduled monument marked on maps as either a Roman town or a cemetery.
The initial interest was sparked by a magnetometry survey conducted by Alan Morris on behalf of FARI Archaeology. This revealed a linear feature running across the site. All areas of the site have turned up RB pottery in the past and we believed the feature may well be some sort of Roman track or road although we expected it only to be a compacted surface. perhaps edged with ditches.
To try and identify the nature and date of the lineation, a trench was opened across the high mag part of the feature. About 40 cm below ground level we encountered a pebbled/cobbled surface which turned out to be the upper layer of a metaled road surface. This is entirely within a Romano-British context with large quantities of RB pottery and a single coin dating to 346 - 347 AD (Constans).
Since we had not at that stage really got much of the ditch and also had not yet investigated any of the high mag response areas on plot, a second trench was opened across the single high mag anomaly on the northern side of the road, sitting on what we presumed would be the ditch.
Although we expected to find the ditch and perhaps evidence of burning or a piece of old iron we instead found a section of walling or path which appears to be of medieval or post-medieval age, lying at the very base of the top soil.
As well as some both RB and medieval pottery, finds from the contexts on either side of the feature included a second Roman coin – as yet undated – and a portion of a fibula brooch.
