A record crowd of 16,000 saw hosts Serbia win their third successive European water polo championship with a 10-8 win over neighbours Montenegro.
The attendance beat the competition record of 11,000 for Serbia's opening 13-6 win over Croatia, with the Kombank Arena's capacity expanded for the clash between the traditional Balkan rivals.
Serbia, who are also the world champions, overcame a one-goal deficit in a strong final quarter.
Having earlier booked a place at the 2016 Olympics in Rio de Janeiro, Serbia were joined by Montenegro who beat the more-fancied Italy and Hungary teams to reach the final.
Serbia beat Malta in the opening match 20-2. It was Malta's first participation at the prestigious tournament.
Meanwhile, Maltese player Steven Camilleri emerged as the top-scorer at the European Waterpolo Championships.
Camilleri, who plays for Neptunes and Ortigia, scored 21 goals in the seven games Malta played. Malta scored a total of 40 goals. Malta finished in 15th place after beating Turkey on Friday.
