 Much of the site was built on in the 1720s to create the Georgian Castle Street.In 1734 Chandos sold the whole of the redevelopment area to Thomas Watts, who sold it the following year to John Anderton, whose descendants continued to clear old buildings and construct new ones.King's Square was built between 1807 and 1814, with many of the buildings incorporating stone from the old castle, although further study would be needed to say how much of their cellars and foundations are in situ castle walls.
