20 {or 30}, The Commissioners of Sewers, Holborn & Finsbury Divisions.
Site: Sewers - Herbal Hill (1 memorial)
EC1, Herbal Hill
"20" (or "30") is not the street number since the building to the left of the plaque is number 2 and we found a number 20 on the other side, up the hill. The street is currently numbered 1-9 on the east side and 10-20 on the west side. Perhaps the street has been renumbered? It could have accommodated over 30 narrow-fronted buildings.
But, whatever the number signifies, we don't understand the function of these plaques - we've found another, very similar at College Place. Can anyone help?
