The île de Nantes (French pronunciation: [il də nɑ̃t], Island of Nantes) is an island located in the centre of the city of Nantes, France, surrounded by two branches of the river Loire—the "bras de la Madeleine" (branch of the Madeleine) at the north and the "bras de Pirmil" (branch of Pirmil) at the south.
The island is 4.9 km (3.0 mi) long and 1 km (0.6 mi) wide due to joining together former small islands in the centre of Nantes, separated by the branches of the Loire river (sometimes referred to locally as the "Boires", as in "Boire des Récollets, "boire de Toussaint" and "boire de la Biesse").
The branches (intervening channels) were filled in during the 19th and 20th centuries.
[1] It is one of the most developed and well-conserved parts of the city while featuring modern buildings such as its major basketball and indoor sports venue.
Many trees and flowers are on the island, which in part helped the city to be recognized as European Green Capital in 2013.
