The S. Roque Fort is an example of modern bastion military architecture, consisting of four bastions arranged at the vertices of an internal polygon forming a rectangle with an access gate to the NW. It was ordered to be built by Manuel Azevedo Fortes between 1705-1710, governor of the Castelo de Vide Fortress. This construction is made of coursed stone masonry with lime mortar, scarped on the outside and with earthworks on the inside. The bastions are pointed with solid brick turrets and revetments. The materials used are: stone (granite), brick, lime, hydraulic lime, sand, and earth. The S. Roque Fort, as well as the entire fortification of Castelo de Vide, have undergone several interventions, the last of which in 2002.

For those planning to hike in the Alegrete area, the main reference route is the PR3 PTG – Percurso de Alegrete. This circular route offers a complete immersion in the Serra de São Mamede Natural Park, combining the medieval heritage of the village with montado landscapes and water lines. The Main Route (PR3 PTG) The PR3 PTG - Percurso de Alegrete is about 11.4 km long and is classified as medium/low difficulty. The recommended starting and ending point is near Fonte Nova, although many hikers start their journey in the village of Alegrete itself to explore the historic center right away. Castle and Village: The Castle of Alegrete is the (literal) highlight of the hike. Situated at about 500 meters above sea level, it offers a panoramic view of the Alentejo border region. Don't miss the Clock Tower (Torre do Relógio). Nature and Biodiversity: The trail crosses areas of cork oak montado, pine forests, and riparian areas. It is an excellent place for bird watching (such as the robin or the titmouse) and, near the water lines, you can find rare vegetation like the royal fern. Religious Heritage: During your passage through the village, you can also visit the small Chapel of Mercy (Capela da Misericórdia), which is part of the local historical complex. Practical Hiking Tips Time of Year: Avoid the months of July and August due to the extreme temperatures in the Alentejo. Autumn and spring are ideal for the colors of the vegetation and mild temperatures. In winter, be careful with the ground, which can become quite slippery on cobblestones and rocky trails. Equipment: Use footwear with good grip (the ascents and descents to the castle and river have sections of loose stones). Bring enough water, as outside the village, refueling points are scarce. Safety and Respect: Always follow the official signage (yellow and red marks).

Far in the northeast of Alentejo lies Castelo de Vide, just a few kilometers from the border with Spain. The town is often called Cidade branca (white city), which is primarily due to the pretty whitewashed houses of the town. The highlight of the town (besides its great location in the Parque Natural da Serra de São Mamede) is the 14th-century Castelo de São Roque. From the castle, you have a fantastic view of the old town. Other sights in Castelo de Vide include the old Jewish quarter with the oldest synagogue in Portugal and the numerous churches and chapels of the town.

This vaulted cistern is located within the castle walls and was probably built around the 9th century to store rainwater for the then Arab village of Ibn Maruán, despite clear signs of remodeling in the late Middle Ages. An impressive site. http://www.monumentos.gov.pt/site/app_pagesuser/SIPA.aspx?id=36148

Castelo de Vide Castle, locally known as Castelo de Vide Castle, is located in the town of the same name in the Alto Alentejo region of Portugal. When the settlement and castle of Castelo de Vide were founded is unknown, but they were first mentioned in 1232, when it was in Portuguese hands. Afonso III of Portugal donated the town and castle, along with the towns and castles of Arronches, Marvo, and Portalegre, to one of his young sons, also called Afonso, around 1272. ... ...The destruction caused during the last two Spanish wars led to the abandonment of Castelo de Vide's fortifications in 1823, after which it fell into disuse... https://www.castles.nl/castelo-vide-castle Due to the small, insignificant castle and access restrictions, we decided not to visit the actual castle.

The current pillory dates from the years immediately following the granting of the New Charter by King Manuel in 1512 and reflects his Manueline, albeit very rustic, style. The monument stands in front of the 16th-century district jail building and next to the clock tower, also from the 16th century, in the square that bears his name. It stands on a base with four octagonal steps and consists of an octagonal shaft set directly into the upper step, formed by five drums with mortar joints.

The Porta de Marvão is a medieval gate in the fortified town of Marvão, serving as the village's main entrance. The town is situated in the Serra de São Mamede mountains and offers panoramic views of the surrounding Alentejo region. Marvão's narrow streets are lined with whitewashed houses featuring Gothic arches and Manueline doorways. The well-preserved 13th-century castle is a focal point, offering visitors a glimpse into the town's rich history and strategic importance. The Porta de Rodão was built much later, in the 17th century, to bolster defenses during the War of Independence against Spain in the mid-17th century. A small parking area is located in front of it. Due to the narrow streets and almost complete lack of parking, driving through the gate into Marvão is strongly discouraged. Another fortified gate, providing pedestrian access to Vila Marvão, is located to the east. This one is also worth a visit.
