is Part 2 (of 6) in a specialist technical study on archaeological resources, produced as part of the Environmental Impact Assessment for Crossrail. It covers the proposed Crossrail route between Westbourne Park in the west and Pudding Mill Lane / Isle of Dogs in the east, and contains an archaeological overview of that route, plus detailed assessments for individual Crossrail sites along it. A full introduction is included in Part 1 of this technical report, which should be referred to for details of the background to the project, project description, structure of the technical report, and methodology. The potential impacts of virtually all of the proposed works on archaeological remains would be mitigated by preservation by record. At Stepney Green, possible impacts from the temporary works on 16th-century and later post-medieval remains will be mitigated by the redesign of the construction compounds which Crossrail has undertaken, and by protective works, providing preservation in situ. There are no significant residual impacts from this route section. 1 0002_R_Central.doc Crossrail Archaeological Impact Assessment: Central Route Section © MoLAS Route overview For an explanation of the purpose and structure of the route overview, please see Volume 1 of the archaeology technical report, section 1.6.5. Zone A: Royal Oak to Hatton Garden Route windows C1 – C5 Sites 199 Westbourne Park, 200 Royal Oak Portal, 201 Paddington Station, 202 Hyde Park Vent Shaft, 203 Park Lane Vent Shaft, 204 Bond Street Station, 290 Great Marlborough Street, 205 Tottenham Court Road Station, 291 St Giles, 206 Fisher Street Vent Shaft and 292 Gray’s Inn Boundaries and layout The zone takes in c 5km of the Crossrail route, beginning at the arbitrary western limit of the Central section. It ends at the western edge of the valley of the former Fleet River, along which ran Hatton Garden and medieval Shoe Lane, adjacent to St Andrew’s Church marking the eastern boundary of the Saxon manor of Eia. Although now heavily built up, much of the area was formerly rural, as reflected in Hyde Park and Lincolns Inn Fields. From the Roman period onwards there was a major road system centred on the road from London to Silchester, approximately on the lines of modern High Holborn, Oxford Street and Bayswater Road (see below). Historic settlements include a Saxon trading centre and medieval villages such as Paddington, Lisson Grove, Tyburn, Marylebone and St Giles: all protected by Local Authority designation as archaeological priority areas. The expansion of London lead to 17th and 18th-century urbanisation on both sides of the Oxford Street arterial road, seen in the street layout of Marylebone, Mayfair, Soho and Covent Garden. Transport infrastructure was still important in the 19th century, eg Paddington Station and the Grand Union Canal. Topography and geology The western end of Zone A lies on an area of exposed London Clay in the Westbourne Green and Paddington areas, to the east of which the majority of the zone lies on the Thames gravels (Lynch Hill terrace). In a few areas the gravels are capped with brickearth (Langley Silt Complex), notably east of Paddington Station. The sequence described above has been cut by the valleys of two former tributaries flowing south towards the Thames.
