[c][1] A bridge and a narrow isthmus, wide enough for a road, connects the island to the coast of Gotland adjacent to the fishing village of Lergrav.

[2] At the beginning of the 21st century, the narrow strait separating Furillen from the main island of Gotland, had become clogged by silt and overgrown with reeds.

Hellström collaborated with Scandinavian designers and architects such as Andreas Forsberg, Mattias Ljunggren, Mats Theselius and Orrefors glassworks.

[17][18] A recording studio close to one of the beaches on the island was planned as part of the project to make Furillen into a center for art and design.

Permission to build the studio was finally denied due to an objection made by the Swedish Environmental Protection Agency regarding the preservation of the beaches on Furillen in their natural state.

The northeast part of the reserve is a meadow close to the water, completely void of trees and shrubs, with a varied birdlife.
