Some 30,000 watched yesterday's Valletta Pageant of the Seas, the Valletta 2018 Foundation has estimated.
The event was part of the 450th anniversary celebrations. It included a swim across the harbour, boat races, and a race where teams raced boats they made from recycled materials.
The spectacle culminated in a display with yachts carrying flags of different EU states, a light and pyrotechnic show from the sloop Fernandes and fireworks.
