By 550 AD London was engulfed in the Saxon advance. London disappeared into the Dark Ages. The Saxons were congenitally averse to urban living; more, they considered the stone buildings of the Roman-British cities to be work of Giants - and so best avoided. London fell into ruin. An Anglo-Saxon poet, wandering around the remains of an unknown abandoned British city, versed his impressions of such a place:
WELL WROUGHT THIS WALL: Wierds [fates] broke it.
The stronghold burst…
Snapped rooftrees, towers fallen,
the work of the Giants, the stonesmiths,
Rime scoureth gatetowers
rime on mortar
Shattered the showershields, roofs ruined,
age under-ate them.
And the wielders and wrights?
Earthgrips hold them - gone, long gone,
fast in gravesgrasp while fifty fathers
and sons have passed
Wall stood, grey lichen, red stone, kings fell often,
stood under storm, high arch crashed -
stands yet the wall stone, hacked by weapons,
by the files grim-ground…
…shown the old skilled work
…sank to loam crust…
