Medinaceli: A Roman Arch and a Ducal Palace on the Edge of the Castilian Plateau

The frontier between Rome and al-Andalus

Medinaceli is a place of frontiers. Perched at 1,030 metres on the rim of a plateau that drops sharply into the Jalón valley, this borgo in the province of Soria was for centuries the contact — and conflict — line between the Christian world and the Islamic one. Its Arabic name, Madīnat Sālim ("city of Salim"), and its triple-arched Roman arch, the only one on the Iberian Peninsula, tell a story spanning two thousand years and two civilisations.

Medinaceli lies on the A-2 (Madrid–Zaragoza), about 150 km from Madrid and 75 km from Soria. The nearest railway station is Medinaceli-Arcos, on the AVE Madrid–Barcelona line, but not all trains stop there — check timetables. By car, the exit from the A-2 is well signed. The climb from the motorway to the borgo is short and scenic.

What to see in Medinaceli

The Roman Arch

The Roman Arch of Medinaceli, dating from the 1st century AD, is a unique monument: the only triple-bay triumphal arch to have survived on the Iberian Peninsula. Built in golden limestone, it stands at the entrance to the borgo with an elegance that time has not diminished. Its dimensions are more modest than those of Rome or Provence, but its position — against the empty sky of the plateau — gives it a grandeur that photographs cannot capture. The precise meaning of the arch is debated: triumphal, commemorative or urban gateway, the answer is buried in the centuries.

The Ducal Palace and the Plaza Mayor

The Palacio Ducal, built in the 16th century by the immensely powerful Medinaceli family (who took their name from the borgo, not the other way around), dominates the Plaza Mayor with its Renaissance stone façade. The square itself, with its irregular paving and wooden balconies, is a perfect example of Castilian urbanism. From the edge of the square, the view over the Jalón valley is vertiginous: on clear days the peaks of the Sistema Ibérico are visible on the horizon.

The Colegiata and the Beaterio

The Colegiata de Nuestra Señora de la Asunción, rebuilt in the 16th century over an earlier mosque, preserves a fine Renaissance interior and a cloister with round arches. The Beaterio (a convent of lay sisters) nearby is an austere building with a quiet allure, now home to a small museum gathering Roman, Visigothic and Islamic archaeological finds from the area.

The Roman mosaic and the castle remains

Beneath the main square, a Roman floor mosaic from the 2nd–3rd century AD can be visited (enquire at the tourist office). The remains of the Islamic castle, on the hilltop, offer few ruins but immense views. A walk along the ancient walls, now partly incorporated into the houses, lets you read the borgo's historical layering like an open book.

What to eat

- Torrezno de Soria: pork belly fried until perfectly crisp, then plunged into boiling oil. The most famous snack of the province of Soria, with its own designation and an annual championship.

- Migas sorianas: breadcrumbs sautéed with garlic, chorizo and pancetta — the shepherds' dish of the meseta.

- Mantequilla de Soria: artisan butter from Soria, celebrated throughout Spain for its quality. Served on toast as an aperitivo.

- Sopa de ajo castellana: garlic soup with egg, bread and smoked paprika — food for cold nights on the plateau.

Restaurante Nico, at the base of the borgo, is the reference point for Sorian cuisine. La Posada de Medinaceli offers a fixed-price lunch menu that represents excellent value.

When to go

The best months are May, June, September and October. Summer days are warm but plateau evenings are cool and pleasant. Winter is cold and windy, with occasional snowfalls that blanket the Roman arch spectacularly. The Toro Jubilo (second Saturday of November) — a controversial festival in which a bull with balls of fire on its horns runs through the streets — is an ancestral event that divides opinions but draws thousands of visitors.

The horizon as philosophy

Medinaceli is a place that trains the eye to look far. The Castilian plateau teaches long vision: there are no obstacles, no distractions, only the line of the horizon meeting the sky. It is a lesson in essentiality that stays with you long after you have left these golden stones, this ancient silence, this wind that never stops blowing.
