Monumental

If you seek his monument, look around you.

...That's the inscription (loosely-translated from Latin) found on the tomb of Sir Christopher Wren in St. Paul's Cathedral in London.  As Wren was the architect of this cathedral, it's definitely accurate.  I think it's somewhat poetic, too...I'd like to go out like that (although I mayyy be in the wrong profession).

In addition to St. Paul's, he designed a chapel in Cambridge, the Sheldonian Theatre in Oxford, the Royal Observatory, and 51 churches in London after the Great Fire of 1666.  He also did some extensive renovations of Hampton Court and Kensington Palace.

Sir Christopher Wren was a real Renaissance man - in addition to these architectural feats, he studied medicine, mechanics, magnetism, astronomy, agriculture, ballistics, and bees (to name a few).
