London is a port city, and Britain became great because of its navy and ability to trade across the globe. The capital’s wealth is built upon that sea trade. There are reminders of London's maritime history everywhere. In Trafalgar Square, we commemorate the 1805 victory (and the death) of Admiral Lord Nelson at the Battle of Trafalgar. At Tower Hill, we remember the 36,000 merchant mariners lost at sea with no known grave. And the Museum of London Docklands examines the triangular trade in goods, sugar and slaves, upon which so much of the city’s wealth was built.

At no time in recent history have we appreciated the NHS and medical staff more than in our current crisis. Doctors, nurses and public health specialists are working flat out to save our nation. Not alone in their endeavours; we are seeing the army and teams of construction workers build new hospital facilities out of conference centres in London, Manchester and Birmingham. These new hospitals are being called Nightingale Hospitals. So, what’s behind the name?
