A TV programme- probably Time Team, although if not something like it- dug
up part of the grounds of Lambeth Palace to try to find the ford over the
Thames which was the means by which Watling Street crossed to what's now
Westminster.

Time Team also excavated a part of Greenwich Park, and found traces of
Watling Street along its proposed "straight" alignment there. The
programme's repeated fairly frequently on the Discovery Channel and is
worth looking out for.
