Source-derived summary

Grönskär (English: The Green skerry) is a Swedish island and lighthouse station located in the south Stockholm archipelago, east of Sandhamn. The island is rocky and the nature sparse. The herb cloudberry has been found on the island. The whole island is owned by the Swedish foundation "Skärgårdsstiftelsen" (English: The Archipelago foundation). since 1964. The foundation also owns the lighthouse since 1984.

History

The Grönskär lighthouse construction started in 1769. Sketchings were made by the architect Carl Adelcrantz. The tower replaced a day beacon that was built 1725, and destroyed in a storm in 1768. The light was an open coal fire.

Editorial analysis

Why this record matters

The phrase “island in the Stockholm archipelego and Värmdö Municipality, Sweden” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Apr 30, 2026. The linked authority identifier is Q33133908. Authority coordinates are 59.278, 19.026. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1964, 1984, 1769 and 1725.

Critical limits

Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
