The Bajo Martín is named after the Martín River, a right-side tributary of the Ebro that flows across the comarca.[2]
Neglect
This comarca was formerly connected with Tortosa by means of a railway line from La Puebla de Híjar. Known as "Ferrocarril del Val de Zafán", the line stretched to Alcañiz and Tortosa. Eventually it was planned that it would reach the sea at Sant Carles de la Ràpita.[3]
Construction work on the railway line began in 1891, but the last stretch between Tortosa and Sant Carles de la Ràpita was never completed before the line was abandoned and the rails dismantled in the last quarter of the 20th century.[4]
