Mare Nordest

Trieste and its sea

Mare Nordest is the event that celebrates the deep bond between Trieste and the sea, an identity element of the Julian city. Created to promote sea culture in all its forms, the festival intertwines science, sport, environment, and outreach in a rich and popular program that has its heart in the majestic Piazza Unità d'Italia, directly overlooking the Adriatic.

The Golden Tridents

Among the most prestigious events of the festival is the awarding of the Golden Tridents, considered the "Nobel Prize of diving": an international recognition that rewards the most important achievements and personalities in the world of diving and sea exploration. A moment of great prestige that brings the world's diving protagonists to Trieste.

Sport, science, and outreach

The program alternates sports competitions and challenges — such as the Traversata delle Tre Nazioni, a scenic open-water swimming event connecting Croatia, Slovenia, and Italy — with workshops, scientific meetings, and educational activities dedicated to marine monitoring, sustainability, and research. An opportunity for students and the curious to approach marine science in an engaging way.

A city celebrating

Organized with the support of the Municipality of Trieste and the Autonomous Region Friuli Venezia Giulia, Mare Nordest is a great popular and cultural celebration that attracts enthusiasts, families, and tourists. Experiencing the festival means discovering Trieste from its most authentic point of view: that of the sea that embraces it and tells its story.
