Viareggio (Italian pronunciation: [vjaˈreddʒo; vi.aˈreddʒo]) is a city and comune in northern Tuscany, Italy, on the coast of the Tyrrhenian Sea. With a population of over 62,000, it is the second largest city within the province of Lucca, after Lucca.
It is known as a seaside resort as well as being the home of the famous carnival of Viareggio (dating back to 1873), and its papier-mâché floats, which (since 1925), parade along the promenade known as "Passeggiata a mare", in the weeks of Carnival. The symbol of the carnival of Viareggio and its official mask is Burlamacco, designed and invented by Uberto Bonetti in 1930.
The city traces its roots back to the first half of the 16th century when it became the only gate to the sea for the Republic of Lucca.
