'Everything about Venice,' observed Lord Byron, 'is, or was, extraordinary - her aspect is like a dream, and her history is like a romance.' Dream and romance have conditioned myriad encounters with Venice across the centuries, but the city's story embodies the hard reality of an independent state built on conquest, profit and entitlement and on the toughness and resilience of a free people.

In this new study of key moments in Venice's history, from its half-legendary founding amid the collapse of the Roman empire to its modern survival as a fragile city of the arts menaced by saturation tourism and rising sea levels, Jonathan Keates shows us just how much this remarkable place has contributed to world culture and explains how it endures as an object of desire and inspiration for so many.
