Still in the same place by Lower Thames Street, you can find one of Wren's Churches - and this one is special. Rebuilt after the Great Fire, Wren transformed the building and made it so bright and airy it became known as "Wren's Lantern". Read about its history here. I'll have to go back and take the inside photo one day - hopefully on a sunny one. A wider view of the deceptively plain exterior is here.
