After visiting this exact place a few months back, I was determined to recreate it in MSFS.
The Hópsnes Lighthouse was built in 1928, which stands close to the now abandoned town of Grindavik, following volcanic activity (as of 2023).
I have modelled this lighthouse in detail while keeping polygon counts low and textures just as large as necessary.
I strongly recommend using this addon for accurate treescapes across Iceland.
