The Anastasio Senra Visitor Center is located in an area of the Marismas del Odiel Natural Park known as Calatilla.
The exhibition, both inside and outside the building, allows visitors to delve deeper into this extensive system of tidal marshes associated with the mouths of the Tinto and Odiel Rivers.
The exhibition reflects the importance of this wetland for the survival of many bird species that, on their migratory routes, stop in this environment, one of the best preserved in Spain.
There is also a reproduction of the swords found in the Huelva Estuary during the dredging of 1923.
