I walked in the back lanes between Cannon Street and Monument. Here is Vestry House on Laurence Pountney Hill EC4.

It is Grade II listed, listed in 1977. The listing says:
Late C19, red brick and stone. Stone doorcase with elaborate overdoor and pediment bearing the initials SP over panel of foliage inscribed Vestry House. 1st floor oriel window with big triangular gable over, projecting on scrolled consoles; 2nd floor windows in gable. Octagonal corner stair turret with pointed roof.
There is a blue tile further East along Laurence Pountney Hill. It reads:
Site of Laurence Pountney Church and Corpus Christi College. Destroyed in the Great Fire 1666
I sketched from a raised walkway on a modern office block opposite. Here are some work-in-progress photos.
I stood in front of the offices of
Bryan Cove Leighton Pilsner
Their logo cleverly captures all these initials.
Here is a map showing the location of Laurence Pountney Hill. The red square is Vestry House, the arrow shows the sightline of the drawing.
The colours are Lunar Earth, Mars Yellow, Perylene Maroon. The grey is Perylene Maroon and Phthalo Blue Turquoise. The green is the same blue with Mars Yellow.
