Chaves, Ancient Keys to the North

A Roman Frontier Town Where Hot Springs Have Healed the Weary for Two Millennia

Wonders of Chaves

Named for the Latin word for keys - for it commanded the gateway between Portugal and Spain - Chaves is one of the most historically layered towns in all of northern Portugal. Romans built their bridge and baths here two thousand years ago; medieval kings raised their castle above the river; baroque architects graced the squares with churches of grand ambition. Today, warm thermal springs still bubble up beneath the town, and the atmosphere remains that of a place that has known importance for a very long time.

The Roman Bridge of Trajano

Spanning the Tâmega river on seventeen elegant stone arches, the Trajan Bridge at Chaves is one of the finest surviving Roman structures on the Iberian Peninsula. Built in the 2nd century AD during the reign of Emperor Trajan, it carried the road that linked Braga and Astorga - two of Rome's most important cities in Hispania. Two inscribed milestones still stand on the bridge, their Latin text worn but legible after nearly two thousand years. To cross it on foot is to walk directly in the footsteps of Roman legions, medieval pilgrims, and countless generations of travellers before you.

The Medieval Castle and Battlements

Rising above the town on a rocky spur, the castle of Chaves is a formidable piece of medieval military architecture, built and rebuilt over centuries to guard the vital northern frontier against Castilian invasion. Its great square keep, the Torre de Menagem, now houses a fine regional museum with collections of Roman artefacts, medieval arms, and local ethnography. The walls and battlements can be walked for panoramic views over the Tâmega valley, the thermal gardens below, and the wild highlands of Trás-os-Montes stretching to the distant horizon - a landscape of elemental, untamed beauty.

The Thermal Baths

Chaves sits above one of the hottest natural spring systems in Portugal - thermal waters that emerge at over 70 degrees Celsius and have been used for healing since at least Roman times. The Romans knew this place as Aquae Flaviae, the waters of Flavius, and built elaborate bath complexes here that served the entire northwestern corner of their Iberian empire. Today, the elegant thermal spa in the riverside gardens continues that ancient tradition, offering treatments in waters rich in sodium bicarbonate. Even those not taking the waters can enjoy the beautiful thermal gardens, a tranquil green oasis at the heart of the town.

The Historic Centre and Praça de Camões

The heart of Chaves is the Praça de Camões, a generous baroque square flanked by the Igreja Matriz and the town hall, shaded by venerable chestnut trees and furnished with café tables that invite lingering. The surrounding streets of the historic centre conceal baroque churches of surprising grandeur, granite-fronted houses with elaborate coats of arms, and the quiet rhythm of a northern Portuguese market town going about its ancient business. Chaves is also famous for its smoked presunto ham and chouriço sausage - the local delicatessens are temples to some of the finest cured meats in the country.
