Designed by Sir Christopher Wren, construction began on St. Paul’s Cathedral in 1675. Finished in 1710, the Cathedral’s 365 foot high dome was the tallest building in London until 1967. While you are not able to take photographs of the interior, I thoroughly enjoyed the skyward reaching, white-gold, archways decorated with bright, colorful, mosaics. The trek up to the top of the dome with a stop at the “Whispering Gallery” was well worth the effort. The views from outside provide a bird’s eye view of the London landscape.
