On the most northern part of Bonaire the ruins of the Malmok station and lighthouse are still remnants of the past. Shortly after building this lighthouse in the beginning of the 20th century, the site turned out to be too close to the sea. As a result another lighthouse, Seru Bentana, was built very close to Malmok. Both Malmok and Seru Bentana are listed as official monuments, as are the lighthouses Willemstoren, Boka Spelonk, Fort Oranje and Punt Vierkant.
