The foundations of the first Roman basilica in London (Londinium) have been unearthed beneath the basement level of an office building scheduled for demolition and redevelopment on Gracechurch street. Much expanded as the conquest of Britain continued through the first century AD, this structure before an open public courtyard would have been the civic centre of the settlement and seat of the administration and judicial and commerce, the public-facing edifice for festivals and announcements. After a series of exploratory excavations, a plan has been developed to create a sublevel access for the archaeological site (see previously), preserving the remains under the high street.
