London tends to measure time by events of grand destruction.
The Great Fire of 1666 destroyed almost every last inch of the medieval city (thatched roofs catch fire pretty quickly). Luckily, a Renaissance genius named Christopher Wren was on hand to rebuild the city, raising over 50 churches and countless other buildings.
The result: the City of London is today an odd architectural mix of medieval houses, Renaissance churches, Victorian public buildings, and postmodern bank headquarters.
