In the section below, we will look at the diverse cultures that have influenced and added unique character to architecture and properties in Portugal, from palaces on Mainland Portugal to castles on the Azores and Madeira Islands.

Islamic influence

The first castles were built in the country (and perhaps even Europe) in the 8th Century following the arrival of Berber and Arab Muslims to the Iberian Peninsula. These castles, known as Hsin, followed the designs of Roman forts found in Syria and the Levant.

More castles in this design were built over the following centuries, coinciding with the Cordoba Caliphate, until the Hsin gradually evolved to match traditional medieval designs. Surviving Hsin castles are still found in many areas of Portugal. Examples of such include Sintra, Alcoutim, and Aljezur.

During the 12th Century, the Almohads brought innovations to castle construction. Some of the best-preserved castles in the country are from this period, and these Moorish designs can still be seen in the Cerca Velha (old wall) of Lisbon and Évora, with the horseshoe gates. Some places in the country where you can find castles in this design are Faro, Silves, and Alandroal.

GC-ICON-95Early medieval castles

The area surrounding the Douro River was well-fortified during the ninth and tenth centuries. However, few of these structures remain because of their relatively basic wood and stone construction. Nonetheless, you can still see signs of this period in a few areas, such as Gestaçô, Penha Longa, and Baião.

From the beginning of the 10th Century, medieval castles became more widespread in the north as feudal lords established control over the Moors. For example, they built more robust castles that can still be seen today in the motte-and-bailey design.

GC-ICON-98Gothic and Romanesque castles

The next few centuries saw a shift from early medieval castles to Gothic and Romanesque designs. As new attack methods arrived, castles were built with strength in mind, more complex designs, and were larger. The rise of Romanesque castles ran alongside local and foreign military and religious orders such as the Knights Temple. Designs increasingly matched the constructions built in the holy land, which can be seen in Minho and Beira.

French influence can be seen in the castles from the 13th Century. This saw the arrival of Gothic architecture. Examples can be seen in the capital, Lisbon, at the famous Castelo de São Jorge (Castle of Sao Jorge) and in Óbidos. You can also see the Gothic design in the north, in Guimarães and Bragança.

You will find a wide selection of architectural styles on mainland Portugal, on the Madeira islands, and on the Azores reflecting the rich history of the country. For example, the São João Baptista do Pico Fortress, built in the 17th Century, has preserved its original Mannerist architectural design, featuring four pentagonal-shaped bastions. If you are seeking out a castle in Portugal for sale, ensure you choose one that is striking for you. A castle is a significant investment, and you will want to ensure you take time to think through your options.
