Plaque: Stoke Newington Manor House
On this site stood Stoke Newington Manor House c. 1500 - 1695 and the terrace called Church Row 1695-1700 - 1936.
London Borough of Hackney
The dates suggest that the terrace was built on the site of the Manor House and that in 1936 the terrace was replaced by the Town Hall. That's confirmed by this GoogleMap.
