The greatest find of Roman antiquities in London, just by Mansion House Tube station, owes its survival to a humble stream the River Walbrook. The brook doesnt run far from Finsbury, on the north edge of the City of London, before emptying into the Thames by Cannon Street railway station.
It has been used as a rubbish dump, covered over and thoroughly ignored for thousands of years but, still, Old Man Walbrook just keeps rolling away. And it is thanks to the Walbrook that some 10,000 objects from Londinium including an unprecedented haul of 250 leather shoes, pewter dinner plates and dozens of wooden writing tablets have survived in better condition than anywhere else in the Roman Empire. In the few weeks left of excavation, even more finds are bound to turn up.
What has emerged is a thickly packed development of long, strip buildings, with ovens, kilns and a mill, nestling up against a Roman temple; a bustling residential, religious and industrial mix. The teeming excavation site in the shadow of Bloomberg Place, where the European headquarters of the financial information empire are due to be completed by 2016 has already been dubbed the Pompeii of the North.
That may be a bit of an exaggeration. But the preservation of the Bloomberg Place artefacts is as good as in the Neapolitan seaside town, thanks to the waterlogged London mud. It didnt just preserve wood and leather; it even kept metal intact with no access to oxygen, the copper brooches, lead plaques of prancing bulls and copper phallus decorations for horse harnesses, couldnt rust.

(3,557 posts)The article stated that Roman London is 23' below modern London. With this in mind, I wonder how many other remarkable ancient sites are located just beneath our feet around the world.

(3,557 posts)I would have guessed that in an urban area with a lot of traffic that, if anything, soil would be displaced over time, not accumulated.
I guess it goes to show that you never know where you'll find the next amazing piece of archaeology. Every once in a while a site that predates all of our expectations is found. I just makes me think that maybe we aren't digging down far enough.
It still boggles my mind
