The Agdenes Lighthouse or Ringflua is a lighthouse on the Trondheimsfjord in Orkland Municipality in Trøndelag county, Norway. The lighthouse sits just offshore at a 90 degree bend in the fjord which leads to the city of Trondheim. The old lighthouse sits on the shore, just a short distance from the present light. The lighthouse is only accessible by boat. It is located about 6 kilometres (3.7 mi) east of Vassbygda. About 6 kilometres (3.7 mi) across the fjord to the north is Brekstad in Ørland Municipality and about 4 kilometres (2.5 mi) across the fjord to the southeast is the village of Hasselvika in Indre Fosen Municipality.

History
editThe original lighthouse building was built in 1804 near the shore of the Trondheimsfjord. That building was rebuilt in 1828. In 1984, the old building was closed and a new light was built on Ringflua, a tiny rock in the fjord, just off the shoreline. The reason that the new light was built just offshore was to make it more visible since the old light was blocked from certain directions.[1]
The new lighthouse is 11.2 metres (37 ft) tall and can be seen for up to 12.39 nautical miles (22.95 km; 14.26 mi). It has an occulting light that blinks white, red, and green over an eight-second period.[2]
