Kavringen fyr

Kavringen fyr is a lighthouse on a small islet in the Oslofjord, just off Norway's capital. It stands on Søndre Kavringdynge at the western entrance to Oslo harbour (about 59.90°N, 10.72°E) and is still an active aid to navigation. From the shore it appears as a small white mark on the water, yet it is one of the most distinctive features of Oslo's maritime scenery.

Why was Kavringen lighthouse built?

Its story begins with an accident. In 1890 the steamship DS "Norway" struck the rocks of the Kavringen islet. The incident showed that the approach to the harbour was poorly marked and prompted calls for better lighting. Construction started in 1891, and the light first shone on 1 August 1892. Ships heading for the capital's port gained a clear landmark at a spot where collisions with underwater hazards had been all too easy.

What does the lighthouse look like?

The tower is a white octagonal wooden structure with a red band, easy to spot against water and rock. A wooden lighthouse in such an exposed position needs steady upkeep, so in 1992 it was rehabilitated, a thorough renovation that extended the building's life.

How has the light changed?

The lighthouse originally ran on gas. In 1932 it switched to electric power, a typical modernisation step for Norwegian lighthouses in the first half of the twentieth century. Sources describe the light differently: one gives the white light a range of around 10 nautical miles, while another notes white, red and green sectors that show mariners the safe line of approach.

A time capsule for a thousand years

A curiosity is hidden inside. In 2000, during celebrations of Oslo's 1000th anniversary, a sealed container of letters and objects was placed in the lighthouse. It is to be opened in the year 3000.

Can you visit Kavringen fyr?

No. The lighthouse is closed to the public, and the islet is a protected seabird reserve. From 15 April to 15 July all traffic around it is banned so the birds are not disturbed during nesting. The best way to see it is from a boat or ferry on the Oslofjord, keeping your distance.
