Most northerly lighthouse

Conforming to the International Association of Marine Aids to Navigation and Lighthouse Authorities' definition of what constitutes a lighthouse, the most northerly example is the Kapp Linné Light at a latitude of 78.06° N, located on the southern side of the Isfjord in Spitsbergen, Svalbard, Norway. The 13-m-tall (43-ft) structure comprises an open metal tower with an enclosed upper section (topped by a light on a post) and was originally constructed in 1933.

The site is also the location of the Isfjord Radio station, which has basic facilities and can be inhabited.

There are more northerly navigational beacons, but these are not considered lighthouses. The Vestpynten Light near Longyearbyen Airport in Svalbard at 78.3° N was previously the most northerly lighthouse but when the old wooden structure dating from the 1930s was replaced with a solar-powered post it could no longer be classified as a lighthouse.

The most northern lighthouse on the Eurasian continental mainland is the 16-m-tall (52-ft) Cape Chelyuskin Lighthouse in northern Russia, an open wooden skeletal tower topped by a light, located at 77.7° N.
