The Guildhall Yard was created in the redevelopment of the Guildhall between the 1960s and 1990s under
the architects Sir Giles Gilbert Scott and his son Richard. Up until the early 1970s, Guildhall yard was only as
wide as the white Porch of the Guildhall. The area was opened up and significant redevelopment of the
area produced new open spaces and a new art Gallery. During this time the archaeological remains of the
Roman amphitheatre were found and excavated.

The Guildhall Yard is paved with a geometric pattern of sawn stone slabs and cobble stones which
utilise a variety of limestones and igneous rocks.
