North Ronaldsay Lighthouse was built in 1852 on the island of North Ronaldsay in the Orkney Islands, Scotland, 43 years after Dennis Head Old Beacon was deactivated. It lies at the north of the island at Point of Sinsoss [Wikidata], and boasts Britain's tallest land-based lighthouse tower. The old fog siren with notable red trumpet was replaced by an electric diaphragm-type horn. That horn was discontinued in favour of a Tyfon horn consisting of 8 mini-trumpets installed on the building that once housed the fog siren. The Tyfon horn gives three blasts every 60 seconds. The electric beeper horn now lies flat on the ground next to the fog signal building, and is still in service today.
