The municipality of Hoz-Costean is made up of the villages of Montesa, Hoz de Barbastro, Salinas de Hoz, Costean and Guardia (now abandoned), all are which are located close to the Sierra de Salinas mountain range. On the surrounding slopes terraces have taken slices from the mountains to create platforms for growing the traditional staples of almonds and olives.
Vineyards have gradually taken over more land on the rolling hills around Montesa. The village occupies an exceptional spot at over 500 metres above sea level, yet is relatively close to the capital city of Barbastro.
The village church dedicated to San Millan stands at the end of the only street facing an 18th century ancestral home adorned with the Pano coat of arms. The regular joint of the church’s north wall and the deep-rooted Gothic nature of the entrance decoration (delicate edging, pretty cantilevers and elegant mouldings) point towards medieval origins. The style and design of the renovation work suggest it was carried out in the early 16th century as can be seen in the simplicity of the vaults with their slightly pointed finish, the delicate sculpture of the sandstone ribs and the decoration of the supporting cantilevers.
The result is a simple space with harmonious proportions in which the stellar vaults attract all the attention.
