Site: Fann Street corner (2 memorials)
EC1, Aldersgate Street
For 56 years this junction had a substantial drinking fountain on the south-east corner (pictured), but now has a plaque on the west side commemorating that fountain, and this south-east corner displays a frieze rescued from the buildings demolished to make way for the Barbican.
In this section Aldersgate Street is effectively a dual-carriageway, which we're sure it was not in 1878, or even in 1934. This excessive road widening probably happened when the Barbican was built.
