Tiermas

Tiermas is an uninhabited settlement in the province of Zaragoza, in Aragon (Spain), belonging to the municipality of Sigüés in the comarca de Jacetania. It is on the banks of the Aragón river next to the Yesa Reservoir that partly floods it.

Of what was the old village, only the upper part of it remains, since the lower part has disappeared under the waters, as has most of its municipal district, along with those of Escó and Ruesta. The construction of the reservoir led to the expropriation by the regime of the entire village, including orchards and farmlands, except for two neighbors who remained in the village until the day of his death.
