1/ The Monument, built in 1674 by Sir Christopher Wren to commemorate the Great Fire of London in 1666 which started in a bakers house in Pudding lane near this spot.
2/ A bit of modern and old, I prefer the old so will concentrate on the building at the front. The Royal Exchange, originally opened by Queen Elizabeth 1 in 1571 to sell Alcohol and valuable goods ot was destroyed in 1666 by the great fire, rebuilt, then destroyed by fire again in 1838, rebuilt and the one you see was opened by Queen Victoria in 1844
3/ St Mary Le Bow Cheapside, there has been a church on this site since medieval tines, but this one was rebuilt after the great fire again by Sir Christopher Wren. It is said you can only call yourself a cockney if you were born within the sound of St Mary Le Bow bell, If you dont know what a cockney speaks like, it's not how Dick Van Dyke spoke in Mary Poppins!. 🙂
4/ Just a street I walked past, but the name made me smile.
