Earlier forms of the name (Obognam and Oboglian) are shown on maps dating to 1469 and 1498.
In the grand scheme of things, Obonjan Island and the Adriatic Sea that surrounds it both formed relatively recently. Some 18,000 years ago, in fact. At the time of the last glacial maximum, sea levels were 120m lower than they are today and the Adriatic Sea was half its current size. Approximately 7,000 years later, the global meltwaters of glaciers flooded the valley and seawaters closed in around Obonjan. The island took shape, emerging from the waters, 1.5km long and 530m wide. Earlier forms of the name (Obognam and Oboglian) are shown on maps dating to 1469 and 1498. Today, it's one of 1,200 small Adriatic islands lying off the west coast of Croatia, located 9.8 km south-west of the city of Šibenik and about 7.3 km south-southeast of the town of Vodice. Only 69 of these Croatian islands are inhabited, and Obonjan is not, technically speaking, one of them.
During the first half of the 20th century, families from the neighbouring island of Prvić farmed on Obonjan. They maintained terraced dry stone walled vineyards and orchards of olives and figs; a farming system in coastal Croatia dating back more than 2,000 years. However, degraded soils and lack of a sheltered port meant that the land was abandoned after the Second World War, soon becoming overgrown with local vegetation. In late 1954, the Šibenik Forestry Department took control, initiating a systematic afforestation programme on the island with Aleppo pine (Pinus halepensis) seedlings, which grew into rich, fragrant areas of forest.
