Interstingly the library does hold a document entitled: Housing Act, 1930 : Official Representation in connection with slum clearance in Mint Lane, Danes Terrace, Danesgate, Grantham St., Occupation Rd, April 1934,
The author of the document was the Lincoln, City Council, Health Department so it looks as if quite a large area, including I presume Danes Terrace, was cleared well before the second world war due I suppose to their insanitary conditions.
