The Roman Baths Museum, recently opened, is a must-see. It is located in Largo do Arrabalde, very close to the current baths. It is the largest Roman bath complex in the Iberian Peninsula. What makes this museum special is that, after an earthquake in the 4th century, the structures collapsed and remained "frozen" in time until they were rediscovered a few years ago. You can see the huge original stone pools where Roman legionaries bathed 2,000 years ago. The Roman Baths Museum What to see: It is the largest Roman bath complex in the Iberian Peninsula.

The Bridge of Trajan (often simply called the Roman Bridge) is, without a doubt, the most important monument in Chaves. It is worth visiting because it is not just an "old stone bridge"; it is a masterpiece of engineering that defines the city's identity. Here are the 4 main reasons why: 1. Walking on 2,000 Years of History This is one of the best-preserved Roman bridges in the entire Iberian Peninsula. It was built between the late 1st and early 2nd century AD, during the reign of Emperor Trajan. The Feeling: Crossing it on foot (cars are forbidden) means you are literally walking on the same stones as Roman legions, medieval merchants, and Napoleonic troops. It is an instant trip back in time. 2. Engineering that Defies Time It is worth looking closely at the structure to understand why it is still standing. The Tâmega River is known for its violent floods, yet the bridge has withstood them for two millennia. The Secret: If you go down to the riverbank, notice the cutwaters (the triangular structures at the base of the pillars). They were designed to "cut" the force of the water and prevent the bridge from collapsing. It is a live lesson in ancient architecture. 3. The Stones that "Speak" (Milestones) In the middle of the bridge, you will find two cylindrical stone columns (milestones) with Latin inscriptions. One of them is particularly important: the "Padrão dos Povos" (Standard of the Peoples). The inscription lists the 10 local tribes of the region (the "Aquiflavienses") who contributed to the construction of the bridge. It is a historical document carved in stone that has survived to this day. 4. The Photogenic Scenery The bridge connects the historic center to the Madalena neighborhood and is set within a beautiful public garden (Jardim do Tabolado). It is the perfect spot to watch the sunset, seeing the reflection of the arches in the water with the Castle of Chaves dominating the landscape high above. Visitor Tip: After crossing the bridge coming from the historic center, turn left and walk along the landscaped riverbanks. There are stepping stones (pedras poldras) nearby in the water that allow you to see the grandeur of Trajan's Bridge from an impressive low angle.

The Historic Centre of Chaves is one of the most fascinating in Northern Portugal because it manages to tell the story of millennia—from the Romans to the Napoleonic invasions—in a compact, walkable area. Here are the 4 main reasons why it is worth visiting: 1. The Roman Bridge of Trajan This is the city's landmark and one of the greatest legacies of Roman engineering in the Iberian Peninsula. Why visit: Crossing this pedestrian bridge over the Tâmega River is literally walking over 2,000 years of history. Built in the 1st century AD, it still maintains its robust stone arches. It is the perfect spot for that classic photo of the city with the river and houses in the background. 2. The Castle Keep (Torre de Menagem) & Views Of the old medieval castle, the imposing Keep (a National Monument) remains, surrounded by a very well-kept garden. The Viewpoint: Climbing to the top offers the best panoramic view over the Chaves valley, the river, and the surrounding mountains. Military Museum: Inside the tower, there is a military museum (symbolic entry fee of ~€1) that explains the strategic importance of Chaves in defending the border against Spain and during the French Invasions. 3. The Colorful Balconies of Rua Direita Rua Direita is the backbone of the historic center. Photogenic Charm: It is famous for its narrow houses with colorful wooden balconies, very typical of this region, creating a picturesque corridor full of traditional shops. Praça de Camões: This street leads to the main square, where the noble buildings are concentrated: the Town Hall, the Main Church (Matriz) with its Romanesque portal, and the Misericórdia Church (Baroque, with beautiful tiles inside). 4. The Thermal Heritage Chaves is the city of water (known as "Aquae Flaviae" to the Romans). Just a short walk away, at Largo do Arrabalde, you will find the Roman Baths Museum, a recently musealized archaeological complex showing how the Romans already utilized these medicinal hot waters. Right next to it, you can see (and taste, with caution!) the water springing out at over 70°C (158°F) at the thermal Buvette. Foodie Tip: Don't leave the historic center without entering a pastry shop to try the authentic Pastel de Chaves (PGI). It is a flaky puff pastry filled with minced veal—the perfect snack while exploring the streets.

The Roman Bridge of Chaves, also known as Trajan's Bridge, is located over the River Tâmega and was built between the end of the 1st century and the beginning of the 2nd century. Along with the development of the thermal baths, it constitutes one of the best Roman legacies of the ancient Águas Flávias, which still stands today, withstanding historic floods and the strong currents of the river. Approximately one hundred and fifty metres long and with a dozen visible arches, the works carried out in the 1930s covered some of the arches and others were still buried in the construction of the houses built there and overlooking the river.[citation needed] In 2008 it became a pedestrian bridge.
