The La Angorilla site is located near Alcalá del Ríos historical centre. This site was used as a Chalcolithic settlement and as a necropolis in the Tartessian and Roman period.
The El Gandúl complex is located on the outskirts of the city and is considered to be one of the most interesting elements of the city's historical heritage, together with the Castle and the fortified site. The complex comprises the following elements: the Marchenilla Castle, the Gandúl Palace and the Necropolis.
This necropolis is one of the few examples of artificial copper age cave tombs, since in that period the use of dolmens was the norm. Other similar tombs have been discovered in the immediate surroundings of Lora de Estepa, Pedrera and Alameda. There are also some near Lisbon, but they are very rare. Tombs of this kind are usually excavated in clayey, limestone marls.
