About Spro Lighthouse

This hexagonal fiberglass tower, standing 7 meters tall, was first lit in 1896 near Nesodden. It features white with two narrow black horizontal bands and a red top, with a focal height of 9 meters. The light emits three white occulting flashes on a 10-second cycle, with red and green sectors indicating specific bearings. This structure replaced a 6-meter square skeletal tower previously at this location. Its geographic range is 10 nautical miles.

Why it matters: Its multi-directional light characteristic helps vessels precisely determine their position along the shoreline near Nordre Sprovei.
