I went on a Wren tour organised by Open City, seeing some churches which I should have known, but didn’t, starting with the surviving church tower of St. Dunstan-in-the-East:-

St. Margaret Pattens:-

A detail from the Monument:-

We stopped for coffee at St. Mary Woolnoth:-

St. Michael’s, Paternoster Royal:-

And the tower of St. James Garlickhythe:-

There were more, but I had to peel off.
