Roberto Ivens

About this dive site

This dive site centers around the "Roberto Ivens", a minesweeper that played a role in wartime operations along the Tagus River. The vessel, originally an English-made trawler called "Lordelo" before the war, was placed in Navy service due to the state of emergency. On July 26, 1917, during a mission clearing the river from German submarine activity, the "Roberto Ivens" experienced a devastating explosion in Lisbon, resulting in its sinking and the loss of all but seven crew members, who were rescued by the tug "Bérrio". The event was preceded by reports of suspected German submarine presence near the Sado and Tagus River mouths. The dive site offers historical significance linked to wartime naval operations. Due to the explosion, there's potential for debris and challenges related to navigating around wreckage. Visibility is likely variable depending on river conditions. There are no specific animal observations associated with this dive location based on the provided information.
