Tierz is located under the protection provided by the hills that form the Estrecho Quinto and on the Hoya plain, along the banks of the Flumen River.

Tierz features a blend of historic farmhouse and new buildings that creates a large and orderly village.

The village historically belonged to the Montearagón Abbey and was documented in the San Juan de la Peña cartulary in 1089.

The houses are distributed around the Parish Church of Nuestra Señora de la Asunción, an 18th-century building made of brick and rammed earth.

The 18th-century Chapel of Nuestra Señora de los Dolores (or Santa Cruz) is nearby.

A well-maintained trail that starts at one end of the village leads to trenches from the Spanish Civil War. There visitors will find information panels on the siege of Huesca and the movements of both sides of the conflict during this dark time in Spanish history.


Tierz celebrates its annual festivals on April 23rd in honor of St. George and on August 16th in honor of St. Roch.
