This is a territorial archive that depends on the Generalitat de Catalunya, the regional government, and was created in 1983. This archive preserves documentation regarding the area of the Ebro river delta, with Tortosa as the main city and one of the rare fluvial ports in the Mediterranean Spain. Among other things, it preserves the archive of the former Ajudantia Militar de Marina de Tortosa, 1816-1954. Since 18th century the Spanish territory has been divide in three big maritime Departments: Ferrol, Cadis (includes the Canary Islands) and Cartagena (includes Catalonia, Valencia, Murcia and the Balearic Islands). Each Department is divided in Maritime Provinces (that have changed along the years) and the main port in every province has a Capitania or main office. Minor offices in small ports were called Ayudantías. Although formally every Capitania should sent old documentation to the capital of the Department (to be sent later to the central archive in Madrid or in Viso del Marques (see AGMAB) most of the local archives have been destroyed or lost. There is no an inventory and it is quite difficult to know about surviving sources.
We have located in this collection few interesting sources useful for SeaLit, under the reference ACTE290-95 / Ajudantia Militar de Marina de Tortosa. The most interesting is the Lista de Inscritos, but as most of the people in that area worked in fishing, by the moment de full study of this source has been reserved for another moment. Other sources for further research are the Libros de Registro de Buques (List of ships) registered in the port of Tortosa and useful for a detailed research on the coastal trade fleet, for example. There are also 4 roles: one of the laud Alfonso XII (1916-17), the laud Largo Caballero (1920—23), both doing river traffic, and two roles of the Anita, the only fluvial steamer operating in the river Ebro in the 1910’s.
