Monzón: A Guide to This Templar Stronghold in Aragon

Rising above the River Cinca, Monzón is a proud little city with a big history. It’s the capital of the Cinca Medio comarca, sitting in the province of Huesca. A dramatic hilltop castle watches over the town, and it’s hard to miss.

Monzón has always sat at a crossroads. Romans, Moors and Christian kings all fought for control here, and Templar knights later called it home. Today, the old town spreads out beneath the fortress, full of narrow streets and quiet squares. It’s a proper slice of medieval Aragon.

The River Cinca also shapes daily life in Monzón, feeding the fertile farmland that surrounds the city. Meanwhile, the streets below the castle buzz with local bars, small shops and a genuinely friendly atmosphere. Whether you’re drawn by knights, castles or good food, Monzón has plenty to keep you busy.

Because Monzón sits between Barcelona and Zaragoza, it makes a brilliant stop on a longer trip through the region. Let’s take a look at what this history-packed town has to offer.

What to see and do

Start with the main event: the Castillo de Monzón, a hilltop fortress with roots stretching back to the ninth century. Templar knights later expanded it, adding a Romanesque church, the Torre de Jaime I and a network of defensive walls. Inside, you’ll find a museum dedicated to the Knights Templar, complete with historical artefacts and displays. Don’t miss the hidden underground passage visible through glass in the church floor, and climb the Torre del Homenaje for sweeping views over the Cinca valley. Because this is Monzón’s top attraction, it’s worth booking your visit ahead of time. Buy Tickets.

Next, head down into the old town to find the Concatedral de Santa María del Romeral, a striking Gothic church with a fortress-like presence of its own. Its solid stone walls hint at centuries of turbulent history. Step inside for a quieter, more contemplative visit.

Afterwards, visit the Casa Museo Natal de Joaquín Costa, the birthplace of one of Aragon’s most influential thinkers. The house now serves as the base for CEHIMO, a local history and research centre. It’s a fascinating stop for anyone curious about the region’s intellectual past.

While you’re wandering, look out for the grand historic buildings scattered through the centre, including the Palacio de los Luzán and the Casa Pano. These elegant façades reflect Monzón’s wealthy merchant history, so take a slow stroll to admire them properly.

Nature lovers might also enjoy a visit to the Centro de Interpretación de la Naturaleza “La Pinzana”, which explores the local wetlands and wildlife along the river. It’s a refreshing change of pace after a morning spent among castles and churches, and it’s especially good for families travelling with children.

Finally, if you fancy some fresh air, head three kilometres south to the Ermita de la Virgen de la Alegría. This peaceful hermitage sits on the site of an old medieval fort, surrounded by open countryside. It’s an easy walk or short drive, and it makes a lovely change of pace.

Local festivals and traditions

Monzón’s calendar is full of colour and tradition throughout the year. Firstly, Easter Monday brings thousands of pilgrims to the Ermita de la Virgen de la Alegría for a lively romería. Faith and festivity blend together here, with music, food and plenty of local spirit.

Then, in May, the town stages its Fiesta Templaria, a historical recreation honouring Guillem de Montrodon. This event has earned recognition as a Festival of Tourist Interest in Aragon. Actors bring the castle’s medieval past vividly to life each year.

Later, the biggest celebration of all arrives in September: the Fiestas Mayores en Honor a San Mateo. Running from around 17 to 21 September, these festivities pack the streets with parades, concerts and fireworks launched from the castle itself. Because entry to most events is free, the whole town gets involved.

Throughout the festival, local “peñas” host their own parties, and a grand carriage procession winds through the main streets. Consequently, Monzón buzzes with energy for almost a week straight. If you only visit once, September is when the town truly comes alive.

The festival’s roots stretch back to a medieval trading fair, once held around 21 September each year. Livestock, grain and craft goods once filled the streets, and echoes of that heritage still shape today’s celebrations.

Later in the year, book lovers should look out for the Feria del Libro Aragonés in December, alongside the town’s beautifully arranged Belén Monumental nativity display.

Where to stay

Monzón’s compact layout makes it easy to base yourself close to the main attractions. Staying near the old town, beneath the castle, puts you within easy walking distance of the cathedral and historic centre.

Alternatively, look for accommodation near Plaza Mayor, the town’s lively central square. This area offers easy access to restaurants, shops and the tourist office, making it a handy base for exploring on foot.

Business travellers and those arriving by train may prefer hotels near the Monzón-Río Cinca station, since it sits within easy walking distance of the centre. This spot works well if you’re planning day trips further afield across Aragon or into Catalonia.

If you’re visiting for the Fiestas de San Mateo in September, book well ahead, since demand rises sharply during festival week. For a quieter stay, meanwhile, consider the streets closer to the River Cinca, where the pace slows and the views improve. Whichever spot you choose, Monzón offers a comfortable, central base for exploring the wider Cinca Medio region. Book Accommodation.
