Loarre Castle

Highlight • Castle

No matter from which perspective, the view of the castle of Loarre is simply impressive. And it is that, located on a limestone promontory, this is the Romanesque castle in the best state of conservation in all of Europe. It was built in the 11th century by order of King Sancho III and in recent decades it has featured in several films, notably Ridley Scott's Kingdom of Heaven.

Aínsa Old Town

Highlight • Historical Site

Here you can step back in time. I had a lot of fun strolling through the small streets.

The old town of Aínsa has an extraordinarily harmonious, uniform overall picture of densely packed houses, from which the beautiful tower of the collegiate church and the huge castle grounds stand out. The latter has almost the same dimensions as the rest of the town. The walls that surrounded the castle are almost completely intact and the numerous monuments in the castle grounds transport visitors back to the Middle Ages.

Jaca Citadel

Highlight • Castle

The great pentagonal citadel is the most imposing structure in the city.

Construction of the complex began in 1592. The occasion was the European religious wars of the 16th century and the strategically important location of the city of Jaca near the border and at the foot of important passes to France. Construction was completed in 1670.
In 2007, a museum of military miniatures (Museo de Miniaturas Militares) was opened in the fortress.
If you want to visit the citadel, you should note that it closes between 1:30 p.m. and 4:00 p.m. After that it's open again until 8:00 p.m.

Montearagón Castle

Highlight • Castle

Founded and built by Sancho Ramírez of Aragón in Romanesque style in the 11th and 12th centuries, Montearagón Castle was a fortified complex that included military housing, a church and a royal monastery.

It is located on a strategic promontory in the Huesca town of Quicena, in the Hoya de Huesca region, Aragon. Although its military function ended with the taking of Huesca and the end of the Spanish-Arab wars, it continued to house the canonical abbey under the name of the Abbey of Jesús de Nazaret de Montearagón.

Several Aragonese kings were buried in the castle in addition to its founder, Sancho Ramírez of Aragón.

Alquézar

Highlight • Settlement

En el Somontano oscense, a 48 kms. De la ciudad de Huesca, se enclava la villa de Alquézar. Encaramada a 660 mts de altitud sobre una de las sierras paralelas al Pirineo, el pueblo se integra perfectamente en un impresionante paisaje de calizas modelado por el rio Vero, que ha creado a lo largo del tiempo un cañón increíble para la práctica del barranquismo, acantilados impresionantes, cuevas de arte rupestre …

Su majestuosa Colegiata fue declarada Monumento Nacional en 1.931 y la arquitectura y trazado medieval de su casco urbano es Conjunto Histórico Artistico desde 1.982.

Paraíso ornitológico, cuenta además con numerosas rutas de senderismo y b.t.t. enclavados dentro del Parque Natural de la Sierra y Cañones de Guara. Desde sus numerosos miradores, los amantes de la fotografía podrán captar imágenes de su salvaje belleza y de los campos de almendros en flor que llenan el aire de su aroma en primavera.

Sin duda, visitar este pueblo es obligado para todo aquel que visite la provincia de Huesca en cualquier época del año.

El origen del conjunto se encuentra en una fortificación árabe construida en el siglo IX y encargada por Jalaf ibn Rasid, con motivo de las luchas contra los carolingios que ocuparon el condado de Sobrarbe. De este periodo no se conservan aparentes restos arquitectónicos. En 1064, tras la toma de Barbastro por el rey Sancho Ramírez, la fortaleza pasa a manos cristianas y se establece una guarnición militar y una comunidad religiosa. Se construyen varias edificaciones, militares y defensivas unas, y religioso otras. El conjunto está rodeado por una muralla de doble lienzo almenado y protegido por varios torreones; uno de ellos utilizado posteriormente por la colegiata como campanario. A la plaza superior se accede a través de una puerta dovelada y mediante una rampa escalonada en zig-zag.

La fundación canónica de Alquézar fue ordenada por el rey Sancho Ramírez y confiada al abad Sancho y adscrito al monasterio de San Cucufate en Lecina, entre los años 1071 y 1074. En 1074 el rey Sancho Ramírez hizo un intento de crear una canónica, aunque en 1080 pasó a pertenecer a Roda de Isábena. Posteriormente, hacia 1083, el abad Galindo inició las obras de ampliación mandando construir las dependencias canonicales y la iglesia de Santa María. Su consagración tuvo lugar en 1099.

Marcuello Castle

Highlight • Castle

The Marcuello castle is located on top, between the Loarre castle and the Riglos mallos, and offers spectacular views over La Galliguera and its imposing mallos. The first long route that I did alone on a bicycle took me to this place and at that moment, when I put the bike on the ground and lay down to enjoy the silence, I realized that from that moment on the mountain bike was going to be a fundamental pillar in my life. And it is that, sometimes, we need to run away to find ourselves.

Samitier Castle

Highlight • Castle

Also called Mondoto Castle, it is a religious-military complex that stands out for the remains of the hexagonal tower of the castle and the hermitage, good examples of Romanesque architecture. The hermitage is dedicated to San Emeterio and San Celedonio and curiously enough, it was actually designed as the first defense mechanism of the castle, since possible attackers had to first cross the place where the monks slept.

Siresa Monastery

Highlight • Religious Site

Arriving at Siresa, it is impossible to ignore the silhouette of the imposing Siresa Monastery. Today the church that we see are the remains of the monastic complex that could be the oldest in Aragon. Legend has it that it housed the Holy Grail between 815 and 831, which is why Siresa is also part of the Holy Grail Route.
