The island was called Insula leporum before being named after Saint Margaret (1242–1270) in the 14th century. Margaret was the daughter of Béla IV of Hungary, and she lived in the Dominican convent on the island.
The Knights of St. John settled on the island in the 12th century.
Margaret Island is a 2.5 km long island, 500 metres wide, 0.965 km2 in area, in the middle of the Danube in central Budapest, Hungary.
The island has a rubber-coated running track measuring 5.35 kilometres.
During World War II and the siege of Budapest, the island was a site of fierce combat.
Administratively Margaret Island used to belong to the 13th district but now is directly under the control of the city.
Since the 1980s, entry by cars has been limited; only a single bus line and taxis, alongside the service traffic of local stores and restaurants, are allowed to enter.
Margaret Island was declared a public garden in 1908.
