Maritime events begin in April with the sailing regatta known as the Settimana velica internazionale. This sailing competition, previously known as the TAN, began in 1981 to celebrate the Naval Academy’s 100th anniversary. The regatta lasts for about a week and teams from all over the world take part in the various races. It normally coincides with the 25th April Liberation Day holiday. A number of related events also take place in the town, especially in the port area, during that week (see the Livorno Now What’s On calendar for specific dates and events).
