Gryten Lighthouse
Location & Light Range
About Gryten Lighthouse
This concrete tower, built in 1947, stands 8 meters tall with its focal height at 6 meters. It is painted white and features a green horizontal band encircling the lantern. The lighthouse emits a sequence of four flashes, alternating between white, red, and green, every ten seconds. This color change indicates the direction of approach for vessels navigating the channel north of Yxlan. While the site is open for visitors, the tower itself is not accessible to the public. The nearest port is Norrtalje, 8.9 kilometers away.
Why it matters: Gryten lighthouse is essential for navigating the channel north of Yxlan, a critical passage within the Stockholm archipelago. Its sophisticated directional light system, which shifts colors based on approach, provides precise guidance, preventing groundings and collisions in these complex, island-strewn waters.
