In wartime situations, it controlled the space between Lisbon and the South, between the Tagus and Sado rivers. During the Islamic period and the Christian offensive in the 12th and 13th centuries, this geostrategic position was compatible with other fortified sites—Coina, Sesimbra, and the Sado riverbank. In the surrounding area—with good conditions for grazing and a large area of agricultural land—some rural communities settled during the Islamic period, such as the village of Alto da Queimada (Serra do Louro). Inside the wall, the ruins of the Church of Santa Maria do Castelo welcome visitors: Palmela's first parish church, probably from the 12th century (founded by King Afonso Henriques?), subject to interventions mainly in the 16th and 17th centuries and severely damaged by the 1755 earthquake. The walls, the pentagonal Keep—a 16th-century construction—are part of the original structure. The castle dates back to the 14th century, where the Bishop of Évora, D. Garcia de Meneses, was imprisoned in the waterless cistern for conspiring against King John II. The bishop died there from poisoning in 1484. The parade ground and barracks are worth visiting. As it stands, the castle is the result of several construction campaigns—repairs, reconstructions, and expansions—up until the 18th century. Archaeological work has identified some sections of the wall from the Islamic period, and other construction phases are recognized, likely dating from the post-reconquest period and, later, from the reign of King John I. The bastion system that surrounds the first line of fortification was commissioned by King Pedro II. In the house of the Prior-Major of the Order, or the military commander of the fortress—after the abolition of the orders (in 1834)—the explorer of African lands, Hermenegildo Carlos de Brito Capelo, son of the fortress's governor, was born on February 4, 1841. Palmela Castle was classified as a National Monument by Decree-Law of June 16, 1910. Parking outside the walls is recommended.

The name Alcácer do Sal comes from the combination of "Alcácer", from the Arabic al-Qasr (meaning castle or palace), and "do Sal", referring to the importance of salt mining in the region since Roman times, when the city was known as Salacia.

Alcácer do Sal is the seat of the municipality of Alcácer do Sal, the second largest municipality in Portugal, with an area of 1,499.87 km² but only 11,112 inhabitants (2021), and is subdivided into four parishes. The municipality is bordered to the north by the municipalities of Palmela, Vendas Novas, and Montemor-o-Novo, to the east by Viana do Alentejo and Alvito, to the southeast by Ferreira do Alentejo, to the south and west by Grândola, and to the northwest, across the Sado Estuary, by Setúbal. The Sado riverside area is a very pleasant place for a walk or bike ride. Here you can also see the immense rice fields.👍🥾

During the summer months, it's possible to visit the island. Unfortunately, access to the Fort of Nossa Senhora da Queimada is not possible. There's a sign in front of the fortress stating its opening hours.

The Fort of Santo Alberto do Pessegueiro, also known as the Fort of Pessegueiro Island or the Fort of Ilha de Fora, is located on the Alentejo coast, on the island of Pessegueiro, in the parish of Porto Covo, municipality of Sines, district of Setúbal, in Portugal. It crossed fires, on the mainland, with another maritime fort: the Fort of Nossa Senhora da Queimada do Pessegueiro, also known as the Fort of Praia do Pessegueiro or the Fort of Ilha de Dentro, in a dominant position over Pessegueiro beach. Both were part of a larger project to defend the Costa Vicentina, which included an artificial port sheltered by a stone breakwater that would connect the island of Pessegueiro to the bordering islet of Penedo do Cavalo and this islet to the mainland. They are currently located in the area of the Southwest Alentejo and Costa Vicentina Natural Park.

The castles in Setúbal are rich in history, reflecting centuries of strategic importance. The Fort of São Filipe, built in the late 16th century, was crucial for protecting maritime trade and defending against naval incursions. The Castle of Palmela, with Roman and Moorish origins, was a vital stronghold during the Portuguese Reconquista and headquarters for the Military Order of Saint James. The Fortress of Santiago in Sesimbra, originally a Muslim settlement, played a key role in the defense of early Portugal after its Christian reconquest.

The Setúbal region generally enjoys a mild climate. Spring (April to June) and early autumn (September to October) are often ideal, offering pleasant temperatures for exploring the outdoor castle grounds and enjoying the views without the intense heat of summer or the heavier rains of winter. These periods are also great for combining castle visits with hiking in the nearby Serra da Arrábida.

The Castle of Palmela is situated in Palmela, which can be reached by train or bus from Setúbal. For the Fortress of Santiago in Sesimbra, buses connect Sesimbra to Setúbal and other nearby towns.
Accessibility varies by castle due to their historical nature and hilltop locations. The Fort of São Filipe, while on a hill, has a pousada (hotel) within its walls, which may offer some accessible areas, but exploring the battlements might be challenging. The Castle of Palmela is a medieval hilltop complex, and while its grounds are extensive, some areas may have uneven terrain. It's advisable to check specific accessibility details directly with each site before visiting.

The Fortress of Santiago in Sesimbra also has no entrance fee, allowing free access to its battlements and the Church of Santa Maria do Castelo.
For a comprehensive visit to a castle like the Castle of Palmela, plan for at least 1.5 to 2 hours. This allows time to explore the walls, visit the Igreja de Santiago church, and enjoy the panoramic views. If you wish to visit the museum or have a meal at the pousada, you might extend your visit to half a day.

This castle, located further south in the Setúbal district, offers historical ruins and wonderful views of the Alentejo coast, often with fewer visitors than the more central locations.
Policies regarding dogs can vary. While many outdoor historical sites in Portugal are generally dog-friendly, especially in their exterior grounds, it's always best to check specific regulations for each castle. For example, while you might be able to walk your dog around the exterior grounds of the Castle of Palmela, access to interior buildings or churches might be restricted.
