The building engulfed in flames is Old St Paul's Cathedral.
Site: Fire, bakers and Hooke (3 memorials)
EC3, Monument Street
The Hooke plaque is the gray square laid into the pavement in front of the strange modern hut-like structure.
The Faryner plaque is on the lowest corner slab of concrete on the charming building behind, to the left (Faryners House, Richard Seifert, 1973).
The bronze MDCLXVI plaque is laid into the cobbles in the middle of the road immediately south of the Faryner plaque. In our photo it's hidden by the hut thing. Probably installed 2006-9 but we don't know.
