The area was named after William Agar, a wealthy lawyer who lived at Elm Lodge, a villa in large grounds near to the Regent's Canal roughly where Barker Drive stands.
[2] The neighbourhood was started in 1841 with Agar's widow leasing out small plots on the north side of the canal.
The company demolished most of the housing to make way for warehouses supplying St Pancras railway station from 1866.
Residential building occurred in the 1960s, including the tower block "Lulworth House".
The oldest remaining building of Agar Town is The Constitution public house.
