Who can forget the wonderful site of the 888,246 handmade ceramic poppies by the artist Paul Cummins filling the moat of the Tower of London and cascading down the walls and over the drawbridge area three years ago? Created to represent every British fatality during WWI and to remember the 100 years since the outbreak of war ‘Blood Swept Lands and Seas of Red’, grew daily, aided in a small way by many Blue Badge Tourist Guides who helped to plant some of them.

London has many street markets that visitors can visit. Smithfield Meat Market and Billingsgate Fish Market are probably the most famous wholesale markets in the capital, but both are facing great challenges. Despite operating for centuries, they face an uncertain future, with supermarkets preferring to deal directly with their suppliers these days.
