About Dyna Lighthouse

Established in 1875, Dyna Lighthouse stands on a rock approximately 200 meters off the Bygdøy coast, west of downtown Oslo. This 12.5-meter wooden structure, built as a keeper's house with a corner lantern, is painted white with a red lantern roof. It emits two white, red, or green flashes every 8 seconds. A fog bell is housed in a steeple above the lantern. The lighthouse was renovated in 1992 into a private banqueting facility, though it remains operational. Its unique design, including a stone wall with an icebreaking prow, gives the impression of a ship sailing the Oslofjord.

Why it matters: Dyna Lighthouse guides maritime traffic in the Oslofjord, the waterway leading to Norway's capital. Its unique architecture and repurposing as a banqueting facility also make it a distinctive landmark and tourist attraction.
