The Royal Mail Mount Pleasant Sorting Office,…
August 1889 CE
It is built on the location of the former Coldbath Fields Prison that had ceased to function in 1885.
The Post Office (Sites) Act 1889 requires the Post Office to provide a portion of the site, or £10,000, to London County Council for use as open space.
The Post Office chooses to retain the entire site, and provides the funds, which are used to purchase Spa Green Gardens in Clerkenwell.
