The city has been declared a World Heritage Site by UNESCO because of its urban structure and architecture.Verona has a humid subtropical climate characteristic of Northern Italy's inland plains, with hot summers and cold, humid winters, even though Lake Garda has a partial influence on the city.The city is predominantly Roman Catholic, but due to immigration now has some Orthodox Christian, and Muslim followers.Because of the value and importance of its many historical buildings, Verona has been named a UNESCO World Heritage Site. Verona preserved many ancient Roman monuments (including magnificent Arena) in the early Middle Ages, but much of this and much of its early medieval edifices were destroyed or heavily damaged by the earthquake of 3 January 1117, which led to a massive Romanesque rebuilding. The Carolingian period Versus de Verona contains an important description of Verona in the early medieval era.The city has three professional football teams.Verona is home to the volleyball team Marmi Lanza Verona (now in Serie A1), the rugby team Franklin and Marshall Cus Verona Rugby (now in Serie A1), and the basketball team Scaligera Basket (now in Legadue).Verona Airport is located 10 km (6.2 mi) southwest of Verona. Now Verona is an important and dynamic city, very active in terms of economy, and also a very important tourist attraction thanks to its history, where the Roman past lives side by side with the Middle Age Verona, which in some senses brings about its architectural and artistic motifs.
