The Benedictine Monastery of San Giorgio was established in 982, when the doge Tribuno Memmo donated the whole island to a monk, Giovanni Morosini. The monks drained the island's marshes next to the church to get the ground for building.
San Giorgio is now best known for the Church of San Giorgio Maggiore, designed by Palladio and begun in 1566.
In the early nineteenth century, after the Republic fall, the monastery was almost suppressed and the island became a free port with a new harbour built in 1812. It became the home of Venice's artillery.
It is now the headquarters of the Cini Foundation arts centre, known for its library and is also home to the Teatro Verde open-air theatre.
