Abstract

Excavations and observations on adjacent sites in the heart of London's ancient harbour produced exceptional evidence of waterfront activity from the mid-first into the fifth centuries. To the south of the natural pre-urban river bank were found substantial traces of structures thought to represent a pier base for a timber bridge across the Thames and an open-work landing-stage. The latter was replaced in the late first century by an infilled timber-faced quay traced for over 70 m east–west. Two storage buildings, each 25 m × 6 m, were laid out over the northern half of the quay area. The line of the waterfront had been advanced beyond the southern limit of excavation by the early second century, and again by the early third century, and these major modifications are reflected in the subsequent development and layout of the buildings and associated features recorded in the excavations.

The well-preserved timber structures are described and illustrated, the development of the storage buildings is discussed in detail, and the first century river level is assessed.

6 A timber from Area B thought to be from the landing-stage could have been felled c. A.D. 50 to A.D. 60, according to the analysis of dendrochronological sample by Jennifer Hillam, University of Sheffield. The timber used in this and the other main waterfront structures was oak, identified by V. Straker, Museum of London.

13 Horrea Galbana, the largest warehouse in Rome, covered 75,000 sq. m (see Rickman, op. cit. (note 12), 5) compared with c. 300 sq. m for Buildings 1 and 2 in London.

14 Rickman suggests that the different plan of some of the Portus buildings may be due to the ‘exigencies of space and the limitations which a harbour shape imposed on the buildings which surrounded it’, op. cit. (note 12), 131.

15 The early third-century building on the east mole was c. 100 m long and c. 13 m deep. See R. Bartoccini, Il porto romano di Leptis Magna (1960), 120; Rickman, op. cit. (note 12), 134–6, fig. 29.

18 Rickman, op. cit. (note 12), 232. Ventilation-openings in the walls were almost invariably associated with raised-floors, whether of timber or tile and cement.

19 cf. the plan of the Trier horrea in Rickman, op. cit. (note 12), 265, fig. 65, and E. M. Wightman, Roman Trier and the Treveri (1970).

20 A discrepancy which cannot wholly be accounted for by London's smaller population.

21 It is also possible that goods were sold directly from these buildings. The open-fronted form of Buildings 1 and 2 is similar to that of the north and east sides of the Horrea Agrippiana in Rome, which Rickman concludes ‘had a purpose that was at least partly that of retailing goods’, op. cit. (note 12), 97.

22 Perhaps near the Forum, some 300 m north of the harbour? The problem of establishment, subsequent ownership and management of horrea is discussed extensively in Rickman, op. cit. (note 12), chapter 5. From the first century onwards, the general pattern is of increasing Imperial intervention in ownership and control of warehouses. In the provinces, ‘… it is certain that the upkeep and control of the horrea… seem normally to have been the responsibility of the governor’, pp. 180–1. If Buildings 1 and 2 are to be interpreted as ‘temporary’ horrea (? transit sheds) operating in association with larger Imperial horrea, then they too should have been under the control of the governor.

23 Of the c. 175 kilograms of pottery recovered from these waterfront deposits, c. 75 per cent were amphora sherds: this contrasts with domestic sites elsewhere in the City where the proportion is usually only 20–30 per cent. (Information from P. Tyers.) Numerous finds of barrel-staves and woodwaste interpreted as broken-up packing-cases also suggest mercantile activity in the immediate vicinity. (Information from B. Davies and C. Rochester.)

I), and for the evidence of a quay on Regis House (Site 2 on FIG. I), see R. Merrifield, The Roman City of London (1965), 284.Google Scholar

25 Not illustrated, but occupied similar area to Building 4 on FIG. 2d.

26 The size of the column fragment suggests that it may have come from the courtyard of a private house, rather than a major public building. (Information from T. Blagg, University of Kent.)

28 Samian pottery from these deposits has been provisionally dated to c. A.D. 120–30, but some of the coarse wares could be as late as 150.

28 Pottery from this deliberately infilled drain has been dated to the later second century. The high proportion and range of finewares can be paralleled on the New Fresh Wharf excavations to the south (see note 30): warehouse clearance?

30 The early third-century quay has been found at Seal House, New Fresh Wharf and, most recently, Billingsgate Lorry Park sites: numbers 7, 8 and 9 on FIG. I. See Miller, L. and Schofield, J., Excavations at New Fresh Wharf, Part I, Roman. (London Middx. Archaeol. Soc., Spec. Pap., forthcoming.) Dendrochronological analysis of timber from the quay suggests a felling date of c. AD. 210, which is compatible with the dates for the pottery from the infill deposits.Google Scholar

31 ‘T’-shaped foundations supporting a vaulted superstructure are known from the Porticus Aemilia in Rome and Trajan's harbour at Portus for example. See Rickman, op. cit. (note 12), 99, fig. 22; and p. 125, fig. 27a.

33 Provision may have been made for temporary lockable shuttering of, for example, wooden slats as in the Horrea Agrippiana. Rickman, op. cit. (note 12), 91.

34 The pottery from the late Roman contexts, including the backfill deposit of this drain, seems to represent a ‘standard domestic assemblage’; with a ‘reasonable proportion’ of finewares to coarsewares and no amphorae. (Information from Caroline Rochester.) cf. notes 23 and 29.

35 The hexagonal Trajanic harbour at Portus provided c. 2000 m of quayside, which presumably functioned with the extensive riverside quays in Ostia and Rome itself. In London there is evidence for c. 70 m of quay east of Fish Street Hill, with at least 150 m to the west (see note 24), a total of c. 220 m. If the fragments of quay observed near St James Garlickhithe (Dyson and Schofield, op. cit. (note 32), 39, pl. 10) and south of Cannon Street station (Marsden, P., London Middx. Arch. Soc. xxvi (1975), 52–4) are part of a continuous development, a maximum length of c. 620 m for the first-century quay could be suggested, since there is some evidence that it did not extend west or east of these points.Google Scholar

40 This change was also reflected on Area A, just north of Area B on the Peninsular House site (see FIG. I), where important evidence for a late Roman fishing industry (which included the native manufacture offish products) was recovered. This represents more evidence for the decline of imported luxury goods, such as Mediterranean garrum and hallec, and their replacement by local commodities in the third and fourth centuries.

41 See note 32. Further evidence of late Roman activity in the area comes, for example, from the town house and bath-building near Billingsgate (site 6 on FIG. I) (P. Marsden, Roman London (1980), 151–5; 180–6) as well as from the buildings and associated features on the terrace overlooking the waterfront on the Pudding Lane and Peninsular House sites, but is outside the scope of this report. In the west of the City, late Roman waterfront occupation was recorded at St. Peter's Hill site: see Britannia xiii (1982), 374.Google Scholar

44 An assessment of the scale and scope of the tidal harbour can suggest the type and size of vessels which might use it. In addition, the well-finished sections of dugout drain excavated on the quayside (PL. 2a) show that the necessary skills to construct a dugout boat existed in London. Barges of the Zwammerdam 2, 4 and 6 type may therefore have been working the Roman Thames. See Weerd, M. de in Taylor, Joan Du Plat and Cleere, H.

46 Medieval riverfront revetments on the Thames utilized smaller timbers, and show the greater economy and skill of the medieval carpenter. See Milne, G. in McGrail, S. (ed.), Medieval ships and harbours in northern Europe, BAR Int. Series, 66 (1979), 145–53.Google Scholar
