Just south of Coopers row, as it is now called was Trinity square, which is the square around the top of the Tower itself. As you can see from the maps in 1896 and earlier in 1720, slightly to the east is Trinity place.
Trinity place is at where the modern underground line now exists, and Tower Hill station.
The London wiki refers to two separate sections of the wall at Trinity place. The northern section was a length of 73 feet of the Roman wall, immediately adjoining the southern section was destroyed for the construction of the Inner Circle Railway in 1882, i.e. the Underground Circle and District lines at Tower Hill.
The southern section was a length of about 50 feet of the town-wall is still standing here to a height of about 15 feet.
Between this point and Tower Hill a considerable stretch of the wall is incorporated in a warehouse and other buildings. The external face is visible in places and appears to be of mediaeval date. Projecting on to Tower Hill is a narrow tenement which, no doubt, stands on the Roman wall.
I will not delve closer inside the Tower of London at present, although this may be a separate subject altogether.
Just a quickie in side the Tower of London and the Wardrobe Tower, thanks to David Fletcher:
