6. St Paul’s Cathedral
The St Paul’s Cathedral was built by Sir Christopher Wren, one of the most celebrated architects of his time. The construction started in 1675 and ended in 1710. It’s said that this building is one of Wren’s finest works. The grand interior of the cathedral will leave you awestruck. You will be particularly mesmerized to see The Whispering Galley, located 30 m above the floor of the cathedral. The most talked about feature of this gallery is its acoustics. Another big attraction of the place is the superb serving of traditional, homemade cakes.
