Known for its mines, Nerva belongs to the Huelva region of Cuenca Minera. It is situated in the east of the province, in a telluric and mountainous landscape typical of the entire Mining Park. It has an emblematic Railway Museum which contains curious photographs of mining trains. Moreover, it has a Modern Art Centre and a Nature Centre.

Nerva was the locality where the train station scenes in Antonio Cuadri’s ‘The heart of the earth’ were shot. Nowadays, the train featured in the film still follows its route around the mines of Riotinto. The director explained that “95% of the scenes were shot in the actual train and only 3 wagons were replicated on set”. Furthermore, Nerva was the setting for the cemetery scenes.
