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 São 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.

Types of Coastal Properties

Original, centuries-old medieval castles for sale directly on the coast are very rare and hard to find. Those that are left are often protected historic monuments. Instead, the real estate available for purchase is grand properties with similar architecture and style. Here are the types of coastal properties that fall into these categories.

Forts or fortresses

Portugal has many historic forts that served as defenses, especially around the coast, like in the Lisbon area or the Algarve. You can find some castles for sale in Portugal that have been converted or built on such historic fortifications, usually for commercial use, like a hotel.

Palatial coastal estates

Portugal has high-end real estate near the coast, such as palaces or manors. These are often grand, ornate, noble residences that look like they were built in the 18th, 19th, or early 20th century. They can have grand architecture, large gardens, towers, or other decorative elements. These luxurious properties can be found in the Algarve, Lisbon, or Cascais area.

In some coastal areas like Sintra or Setúbal, quintas may have historic main houses large enough for the property to resemble a castle or a manor. While it is difficult to find abandoned castles for sale in Portugal, coastal quintas can create a similar imposing appearance.

Step 1: Find a good lawyer

When you are looking to buy a castle, it is highly recommended to have an experienced Portugal real estate lawyer to help you navigate the process.

The process may be more cumbersome as you invest in sites of historical importance to Portugal.

A good lawyer will be able to assist you with the legal aspects of buying a historic site, such as a castle for sale in Portugal, ensuring that you have all the documents that you need and practicalities and deadlines to be aware of in the process.

GC-ICON-95Step 3: Do your due diligence

Visit the castle and make sure that everything is in order. This is a substantial investment, so hire a surveyor and triple-check everything to ensure everything is as it should be. Old properties often require considerable maintenance, so bear this in mind when doing your due diligence checks. Also, there will likely be additional maintenance costs with historical properties after the purchase.

GC-ICON-57Step 4: Taxes and additional costs

You must be aware of the taxes associated with buying property in Portugal. Your lawyer will be able to help with this.

At the time of purchase:

  • Imposto Municipal sobre Transmissões Onerosas de Imóveis (IMT) (Municipal Tax on Onerous Transmissions of Real Estate)

Ongoing taxes:

  • Imposto Municipal sobre Imóveis (IMI) (The Municipal Property Tax)
  • Notary fees

The exact process of purchasing any property will be in place.
