Arrival of the railway in Tardienta Historical milestone · Tardienta, Los Monegros, Huesca Image of Tardienta, not of the place itself. On 16 August 1861 the first train entered Tardienta, which became a railway junction between Zaragoza, Huesca and Lérida. The station preserves that role: it is the smallest municipality in Spain at which the high-speed service makes a stop. 1861 Photo: Fran Ara (CC BY-SA 4.0) What to see and do in Tardienta
