Archaeologists who set out to put up a safety fence at
Rochester's medieval castle have unexpectedly uncovered a city wall
from Roman Durobrivae.
The team had "barely taken the turf off when they unearthed a
solid mass of stone masonry", Medway Council said.
Castle archaeologist Graham Keevill called it "a very important
He said: "We don't have many Roman city walls surviving in
England. To get an unexpected one like this is fantastic. It is also
a perfect example."
He said the wall had "high-quality" facing stones on each side,
and its rubble core, made up of stone, flint, sand, and gravel,
would have been poured in "to set hard almost like concrete, to bind
the whole wall together".
Builders who came later in the twelfth century "knew good
masonry when they saw it" and used the 6ft-wide (1.8m) Roman wall
for the foundations of their medieval castle keep, Mr Keevill said.
The pits will be re-covered to preserve the find, and the safety
fence will be realigned.
