April 20, 2026, Castelo de Vide

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.

The castle was founded by King D. Dinis in 1290, with the aim of defending the Alentejo border. Originally, it had an imposing structure with a double ring of walls, twelve towers and eight gates. Over the centuries, it lost part of its structure to the growth of the city, but it remains a National Monument. The Keep is the best-preserved part of the original complex. Inside, there is a museum that you can visit.

Located in the parish of Seda, in the heart of the Alentejo, the ruins of the walls that surrounded the ancient castle of Seda remain determined to preserve their ancient history. Without official evidence, some studies point to the existence of a castro of the Lusitanian tribe, occupied by Roman troops who would have erected a fortification there. The Roman presence in the region is well-known, and easily attested to by the Vila Formosa Bridge (1st and 2nd centuries), milestones, and the military road that would have connected Lisbon to Mérida. In 1160, King Afonso Henriques conquered the village, which at the time was called Arminho, from the Moors and donated the fortification to the Templars. This is the date that marked the beginning of the village's original enclosure. During the reign of King Afonso III, the village was handed over to the Order of Aviz and was later elevated to the status of a town, even serving as the municipal seat until 1836. The castle, however, gradually lost importance, and only a section of medieval wall, reinforced with turrets, has survived to this day. It has been classified as a Property of Public Interest since 1982.

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 fortified town of Marvão, 12 kilometers from Quinta do Pomarinho, is also known as the "Eagle's Nest." It boasts a spectacular location on a granite cliff, atop one of the peaks of the Serra de São de Mamede mountain range. Completely walled, Marvão is situated in the Alto Alentejo region, near the Spanish border, which was once controlled from the village. The town of Marvão owes its name to Ibn Maruane, an Arab military leader who sought refuge here in the 11th century. He hid on Mount Ammaia and built a castle there, in the most remote and inaccessible spot he could find. Years later, the castle was transformed into a medieval fortress. Its location made it a strategic defensive position, nestled among hills with slopes to the north, south, and west, accessible only on foot from the village. For many years, Marvão was a municipality heavily and significantly involved in numerous military conflicts in the region. Today, Marvão is a rather sleepy town, but one where you can enjoy wonderful walks. More information can be found here: https://www.feriasemportugal.com/marvao

Marvão is dominated by its imposing and well-preserved medieval castle. The fortified walls embrace the entire village, enclosing a maze of narrow cobbled streets, white houses with red roofs and small flower-filled squares. The views from the walls are breathtaking, taking in a vast panorama of hills, valleys and, on a clear day, all the way to the Serra da Estrela mountain range. Marvão is a true open-air museum, preserving the atmosphere and architecture of centuries past. It is on the UNESCO tentative list of potential World Heritage Sites, and is an ideal destination for those seeking history, tranquility and spectacular scenery.

Mural in homage to the Alter Real Initially called Alter-do-chão, but later its name was changed to Alter-Real, the breed is descended from Andalusian horses brought from Spain. Between 1809 and 1810, the breed was threatened during the Napoleonic invasions, when General Junot's French troops stole the best specimens of the breed. Crossbreeding with Thoroughbreds and Arabians weakened the breed, causing a great loss of its racial character, with 12 pure Zapata mares of the breed remaining. They were saved from extinction through the importation of three Andalusian stallions in 1992 directly from Jerez de la Frontera in Spain. At the end of the 20th century, measures were taken to restore the Alter-Real to its former characteristics and its best use in the modern world, in addition to its preservation. Today, the reproduction of the Alter-Real is controlled by the Portuguese Ministry of Agriculture and its use is in Equestrianism and Dressage and it participated in the formation of the Brazilian Manga-Larga Paulista and Manga-Larga Marchador horses at the beginning of the 19th century.
