NHER 26591 (Monument record) - Undated welll or chalk pits, 71 and 73 Gladstone Street

June 2001. Hole approximately 3m wide opened on boundary between back gardens of 71 and 73 Gladstone Street.
Infilled with sand by City Council before visit.
Stated to be about 2m deep but with loose material in base, however residents say it was much deeper and that chairs, slabs etc fell into it. See (S1).
Seven tons of sand used to backfill.
Council state investigations by Harrison & Co. show water level at 9m OD and therefore this could not have been a chalk mine.
[1] says she has seen a map of around 1870 at Norfolk Record Office which marks a well at this location which was then 26 Victoria Street. However 1883 first edition 25in map shows house pattern and street name as now, no well.
Published map of Norwich subsidences show two dots very close to this site so mines not impossible.
