Tourism is the most significant industry in central Florence. From April to October, tourists outnumber local population. Tickets to the Uffizi and Accademia museums are regularly sold out and large groups regularly fill the basilicas of Santa Croce and Santa Maria Novella, both of which charge for entry. Tickets for The Uffizi and Accademia can be purchased online prior to visiting. In 2010, readers of Travel + Leisure magazine ranked the city as their third favourite tourist destination. Studies by Euromonitor International have concluded that cultural and history-oriented tourism is generating significantly increased spending throughout Europe.
Florence is believed to have the greatest concentration of art (in proportion to its size) in the world. Thus, cultural tourism is particularly strong, with world-renowned museums such as the Uffizi selling over 1.6 million tickets a year. The city’s convention center facilities were restructured during the 1990s and host exhibitions.
