Definition
Agdenes Lighthouse (Norwegian: Agdenes fyr) is a coastal navigation aid situated in the vicinity of the village of Agdenes, at the mouth of the Trondheimsfjord in Trøndelag county, Norway.
Overview
The lighthouse serves to mark the entrance to the Trondheimsfjord and to guide vessels navigating the coastal waters of central Norway. It is part of the Norwegian coastal lighthouse system, which has been maintained by the Norwegian Coastal Administration (Kystverket). The structure is positioned on a small promontory that projects into the fjord, providing a clear line of sight for maritime traffic entering and leaving the fjord. The lighthouse remains operational, although its original keeper’s house has been repurposed or is no longer inhabited.
Etymology/Origin
The name “Agdenes” is derived from the local place name, which historically referred to the surrounding area. The exact linguistic origin of the toponym is not definitively established, but it is generally understood to be of Old Norse origin, possibly related to the word agn meaning “point” or “edge,” reflecting the site’s protruding coastal position. The addition of “Lighthouse” simply denotes its function as a beacon.

| Location | On a promontory near the village of Agdenes, at the mouth of the Trondheimsfjord, Trøndelag, Norway. |
| Construction | The tower is constructed of masonry (brick or stone) with a cylindrical shape, typical of 19th‑century Norwegian lighthouses. |
| Height | The tower stands approximately 12–15 metres (40–50 ft) tall; the focal height of the light is higher due to the elevation of the site. |
| Light characteristic | Emits a fixed white light (F W) or a flashing pattern (e.g., three flashes every 30 seconds) depending on the most recent equipment upgrade; the exact current characteristic is not confirmed. |
| Automation | The lighthouse was automated during the late 20th century, a process common to many Norwegian lighthouses; the specific year of automation is not verified. |
