Archaeological investigations at seven sites within the Finsbury Square
area have revealed important evidence for the medieval and post-medieval
development of this former marshy area north of the city walls. At
127-139 Finsbury Pavement, quarry pits may relate to the development of
the 12th- to early 13th-century Finsbury manor house, documented from
1272. Features identified within the manor include a gravel courtyard
and the fragmentary remains of a building with masonry foundations. A
moat existed to the east of the manor house by the 14th/15th centuries,
but was backfilled by the end of the 17th century and then built over.
Beyond the manor, widespread quarrying and brick manufacturing occurred
during the later 15th century. At 27-30 Finsbury Square, large
quantities of leather waste may have been dumped in the 15th and 16th
centuries from nearby workshops. Quarrying continued on several sites
into the late 16th century. A gravel surface and a boundary wall at the
Honourable Artillery Company site represent the enclosure of the area to
the north of the manor as the New Artillery Ground in the 1640s. A brick
flue and a saw pit at 25-32 Chiswell Street reflect the increasingly
industrial nature of the area to the west of the New Artillery Ground
during the 18th and 19th centuries which is indicated on contempoary
maps.
