A 6 kilometre trench was excavated between Histon, Cambridgeshire (c. NGR 544050 264500) and the Cambridge Research Park, near Waterbeach, Cambridgeshire (c. NGR 547700 267900) for an underground electricity cable. An archaeological watching brief was undertaken which produced evidence of Iron Age and Romano-British activity.

During two weeks in April 2005 a �strip, map and sample� excavation was undertaken at Mayton Wood, Buxton with Lammas, Norfolk (NGR: 624170 32144). This was further to work undertaken by the Cambridge Archaeological Unit (CAU) during April 2004. Six linear features were recorded, two of which formed a continuation of a north-west - south-east route way of possible Romano British date, extending along the south-western edge of an enclosure identified by the previous phase of excavation. Two of the remaining linears formed another enclosure ditch or possible second north-east south-west route way. With no dating evidence recovered, a Romano British date for these features is most probable. A single post-medieval ditch was also recorded. Eleven small burnt pits similar to those revealed by the previous phase were recorded. These were probably charcoal burning pits of Anglo-Saxon date.

Trial trenching for the tenth phase of archaeological investigation at Broom Quarry, Bedfordshire (centred TL 175 440) was undertaken by a team from Cambridge Archaeological Unit in August 2005. The work was carried out on behalf of Tarmac Southern Ltd in advance of gravel extraction. It comprised a programme of targeted trial trenching and artefact sampling over an area of 9.5 ha. It revealed a single pit of probable prehistoric origin, and Romano-British droveways and field boundaries relating to 1st-2nd century AD settlements along the edge of the River Ivel floodplain to the east.

During August and September 2005, staff from the Cambridge Archaeological Unit carried out monitoring on a series of 27 hand-excavated test pits situated within the area of St John�s Triangle, Cambridge. This also provided an opportunity to assess the character, extent and preservation of archaeological deposits as exposed within the test pit sections, and to retrieve dating evidence such as ceramics. Being located within the heart of Medieval Cambridge, a significant depth of archaeology was expected based on the results of other excavations within the immediate vicinity. Within areas of open space, such as the back yards, up to three metres of stratigraphy was noted from the test pits and additional borehole data. Areas that had been cellared would normally be assumed to have little if any surviving archaeology. However, this study demonstrates the survival of horizontal stratigraphy and the fills of cut features at this low level up to one metre in depth. It is also clear that 18th/19th century activity outside of the cellared areas has had a limited detrimental effect on the earlier strata. Traces of a compact gravel surface, provisionally dated to the Roman period, were exposed along the Bridge Street frontage below the level of the cellar floors. Saxo-Norman pottery was also recovered from several test pits in the southern half of the development area. Evidence for the truncation of the underlying natural gravels was also evident and it is possible that the presence of a large feature such as St John�s ditch, believed to run across the southern half of the area, may be a factor in explaining the differentiation in natural height between neighbouring test pits.

This report details the evaluation fieldwork undertaken between late march and October 2004 by the Cambridge Archaeological Unit (CAU) within the environs of the village of Longstanton, Cambridgeshire.

Trial trenching at Bridge Farm, Earith, Cambridgeshire (centred on TL 3983 7650) was undertaken by a team from the Cambridge Archaeological Unit (CAU) in August 2005. The work was carried out on behalf of the landowner, Mr Latta, in advance of the planned construction of an agricultural reservoir. The project involved trial trenching over an area of 17.5 hectares. One undated pit (possibly Early Bronze Age) and three undated �ditches� with associated banks (possibly Bronze Age) were found. In addition, important light was shed on the character of the palaeoenvironment in the area. `

Detailed survey was carried out on nos. 12 to 25 St. Andrew�s Street, Cambridge, between November 2004 and June 2005. This was as part of the work required as condition on Listed Building Consent and Conservation Area Consent, which required: (1) Listed Building Consent: �desk top study of the above ground history and archaeology of the entire site and a full photographic survey and evaluation of all pre-1939 buildings�. ????Conservation Area Consent: �desk top study of the above ground history and archaeology of the entire site and a full photographic survey and elevation of all post-1939 buildings�. This document represents an interim report on recording work in the four Grade II listed buildings, nos. 22-25 St. Andrew�s Street only.

In October and December 2005, trenches were excavated across the predicted line of the Arbury Camp ditch circuit. Two were cut along the southeastern perimeter (in the Car-zone lot) and these confirmed the presence and survival of the ditch in an area heavily disturbed through levelling and service construction; no evidence for the bank survived in either. Another trench was dug along the northeastern perimeter of the enclosure, which further confirmed its exact alignment/position. In addition, a final trench was dug along the eastern margin of the overall development site. Intended to check upon the presence/absence of archaeology adjacent to the projected line of the Roman road within the area of the �Unex Lands�, its result was entirely negative.

An archaeological evaluation carried out in the grounds of the Edith Cavell Hospital, Peterborough, demonstrated an archaeological �blank�. Seventeen trenches produced two pieces of worked flint, a single of prehistoric potsherd and a fragment of bottle glass, but no archaeological features. Headland or sub-soil deposits were present within trenches located across the southern half of the evaluation area, whereas the northern most trenches indicated a truncated zone perhaps associated with the construction of the current hospital buildings.

This archaeological desk top assessment was requested by Wenbridge on behalf of the Ventress Group to assess the likely impact of development of a 0.77ha site centered on TL488574, just north of Coldham�s Lane in the Cambridge suburb of Cherry Hinton. Evaluation of the archival, aerial and cartographic evidence shows the site to be located in an area of rich archaeological and historical significance, with a low probability of archaeological features remaining in-situ on site.

A team from Cambridge Archaeological Unit undertook evaluation by trial trenching in September 2005 on 28.4 ha of land east of Bedford, between Renhold (north) and Willington (south), centred at TL 115 505. The evaluation followed initial investigations by geophysical survey and was designed to determine the presence or absence, extent, date, state of preservation and significance of any subsoil archaeological features. The evaluation was commissioned by Lafarge Aggregates Ltd and the Written Scheme of Investigation was drafted by Archaeologica Ltd. Evidence for prehistoric activity was identified across the landscape in the form of negative features and artefacts.

During the months beginning 13th April 2005 through to the 8th August 2005, a small team from the Cambridge Archaeological Unit (CAU) undertook an archaeological investigation at Longstanton, Cambridgeshire. This project was commissioned by WSP Environmental on behalf of Gallaghers Ltd ahead of the proposed development of the land and in response to an evaluation in 2004. The site was located at Striplands Farm, approximately 9km north of Cambridge, within the village of Longstanton (NGR: 539330 267900 (TL 394 673)), where a series of fields were subjected to open area excavation.
