It is not clear whether Londinium was first used as a Roman military camp. Certainly it soon became a centre of supplies. In its first stages we must imagine a cluster of small dwellings with clay walls, thatched roofs and earthen floors; narrow alleys ran between them, with a series of streets connecting the two main thoroughfares, filled with the smells and noises of a busy community. There were workshops, taverns, shops and smithies crowded together while, beside the river, warehouses and workshops were grouped around a square timber harbour. Evidence for such a harbour has been found in Billingsgate. Along the thoroughfares, which every traveller to London used, there were taverns and tradesmen. Just beyond the city were round huts, in the old British style, which were used as places for storage, while on the perimeter of the city were wooden enclosures for cattle.
Only a few years after its foundation, which can be approximately dated between AD 43 and 50, the Roman historian, Tacitus, could already write of London as filled with
London is based upon power, therefore. It is a place of execution and oppression, where the poor have always outnumbered the rich. Many terrible judgements of fire and death have visited it. Barely a decade after its foundation a great fire of London utterly destroyed its buildings. In AD 60 Boudicca and her tribal army laid waste the city with flame and sword, wreaking vengeance upon those who were trying to sell the women and children of the Iceni as slaves. It is the first token of the city’s appetite for human lives. The evidence of Boudicca’s destruction is to be found in a red level of oxidised iron among a layer of burnt clay, wood and ash. Red is London’s colour, a sign of fire and devastation.
There was at least one other tribal attack upon the Roman city, at the end of the third century, but by that time the city and its defences were strong. Immediately after the Boudiccan assault the work of rebuilding was begun. If you were to stand now at the great crossroads in the City, where Gracechurch Street divides Lombard Street from Fenchurch Street, you would be facing the main entrance of the Romans’ public forum, with shops and stalls and workshops on either side. The new forum was constructed of ragstone from Kent, carried by boat up the Medway, and, with its plastered surfaces and its roofs of red tiles, was a small fragment of Rome placed upon an alien soil.
Yet the influence of Roman civilisation was enduring in more than one respect. The chief cashier’s office in the eighteenth-century Bank of England was based upon the design of a Roman temple, very like the basilica situated to the left of the early forum. Throughout the centuries London has been celebrated or denounced as a new Rome-corrupt or mighty, according to taste-and it can safely be said that part of its identity was created by its first builders.
