Overlooking the canal, the Ribeirinha lighthouse was one of the more important landmarks on the island. It was mentioned in many works of the Portuguese writer Vitorino Nemésio, who wrote the ex-libris of the lighthouse in his work "Mau Tempo no Canal". The lighthouse is a square form, covered in white azulejo (tiles); a rectangular base, featuring a central tower. Construction began during the month of May, 1915m and inaugurated in the winter of 1919 (November 1). Its optic (made from crystal) and lantern (partly red) distinguish it as a unique World Heritage artifact. Following the earthquake of 1998, the building was abandoned due to major cracks and deterioration of the internal structure. Following the earthquake, which was centered 5 km off the coast of Ponta da Ribeirinha, the lighthouse was left in ruins. A preemptive demolition of the building in 2001 was abandoned following a campaign of the "Liga dos Amigos do Farol" (the "League of Friends of the Lighthouse"). Their objective to preserve and reconstruct the lighthouse has not yet materialized. Meanwhile, the older equipment has been placed in the possession of the Casa do Povo da Ribeirinha.
