St. Paul's

St. Paul's is the absolutely enormous cathedral in the heart of London, designed by architect Christopher Wren. Wren designed many of the iconic buildings in London after the great fire of 1666 (before then, London buildings were mostly of wood). Happily, Wren worked in stone and, despite other fires, many of his buildings are historic landmarks today.

We were not allowed to take pictures in the building, but here's one shot of the exterior. Mind you, this is a modest side-view:

Prior to visiting St. Paul's, I knew of it only from the movie Mary Poppins. I was pleased to see that feeding pigeons on the steps of the church continues today, though I did not see a woman selling birdseed for tuppence-a-bag.
