The lighthouse in Portocolom is called Far de Sa Punta de Ses Crestes. Its tower has a height of 82 m with the light signal being 137 m above sea level. The lighthouse was built in 1863, rebuilt in 1965 and modernized in 1993. Supposedly the grounds are open to the public (but not the buildings), however, I have never found the gates open on any of my numerous visits. Perhaps you will be luckier than I was. The building is inhabited by a young couple who live there rent free in exchange for rendering the duties of lighthouse keepers.
The signal emits two white flashes every 10 seconds; the signal range extends to 10 nautical miles.
