Ventilation shaft, Gibson Square
“Pastiche architecture has mostly been quite rightly eschewed in Barnsbury. The notable exception is in the central public gardens of Gibson Square where in 1966 Raymond Erith and his protege assistant Quinlan Terry came up with the cunning solution of disguising a potentially monstrous ventilation shaft for the new Victoria underground line as a delicate classical temple. This was based somewhat loosely on the Pantheon, with the frieze derived more appropriately on the Tower of Winds”. – from 20th Century Buildings in Islington, Alec Forshaw, The Islington Society, 2001.
