please natural speed with pauses when mentioning new buildings or landmarks, I'm going to show slides.
Architecture
London's buildings have varying ages, so they are too diverse to be characterised by any particular architectural style.
Many grand houses and public buildings, such as the National Gallery (1824), are constructed from Portland Stone (Dorset).
Some areas of the city, particularly those west of the centre, are noticeable for their whitewashed buildings.
Older buildings are mainly brick built, most commonly the yellow London stock brick or a warm orange-red variety, often decorated with carvings and white plaster mouldings.
Only a few structures in central London survived the Great Fire of 1666, for example the Tower of London (founded in 1066) and some Tudor survivors in the City such as
the Royal Exchange (1565) while some railway stations are excellent examples of Victorian architecture, most notably St. Pancras and Paddington.
Very famous are also Wren’s late 17th century churches such as Saint Paul’s Cathedral and the financial institutions of the 18th and 19th centuries such as the Bank of England (1694),
to the early 20th century Old Bailey and the 1960s Barbican Estate and the most recent:
the Shard by the Italian architect Renzo Piano.
I am not 100% certain of my pronunciation of certain British building names.
