The former site of the gas holders connected to the formerly adjacent gas works is still visible in outline on the 1999 Cities revealed aerial photography. This part of the gas works was retained after the conversion to town gas (probably as a storage and distribution point) and is shown on the 1985 OS 1:10000 sheet as a 'Gas Service Centre'. Before the construction of the Gas works this was the site of Car(r) House - an elite residence with formal gardens to the south. This house was in existence from at least 1643 when it was the home of Parliamentarian Henry Westby (Munford 2000, 63).
