Blessington Road dates from the mid-Victorian period.
The railway arrived in Lewisham in 1849 and by the 1850s, the first houses were appearing on the new Blessington Road.
Constructed as single middle class family houses complete with accommodation for servants, by the Second World War most houses in the street had been subdivided into flats.
Blessington Road suffered during the Second World War with a deadly bombing taking place on 29 June 1944 destroying houses and lives.
The Mercator Estate is a mixture of a terraces of houses facing onto Belmont Park
and another eight houses north of Saxton Close
. There are a series of blocks: Chesney House, Ericson House and Clavering House, on Mercator Road
and Blessington Road; along with the Rawlinson House tower block.
