Sir Christopher Wren

Renewed my Friends Membership for St Paul's Cathedral. 
This very plain memorial to Christopher Wren is most fascinating - in fact you could easily miss it. It is located in the crypt and not particularly visible or highlighted in anyway.
It says this:
Here in its foundations lies the architect of this church and city, Christopher Wren, who lived beyond ninety years, not for his own profit but for the public good. Reader, if you seek his monument - look around you. Died 25 Feb. 1723, age 91.

Extra - copy of his death mask!
