Here's the first - St. Paul's Covent Garden. The face that you see in the square is actually the back of the Church. There is no door here, although it looks as if there should be. The entrance is on the other side, in the Churchyard. Built by Inigo Jones for the 4th Earl of Bedford in 1631, it is also known as the 'Actors' Church'. Here's the 'before' by Hogarth.
And here's the after.
