In Sintra, the most expensive properties are typically historic villas and palatial estates, many of which are located within the UNESCO World Heritage Site. Particularly sought-after are properties with traditional Portuguese architectural features, such as ornate tile work and intricate stone facades. The region's luxury market is also bolstered by estates that boast expansive gardens and sweeping views of the surrounding hills and the Atlantic Ocean. For example, the Quinta da Regaleira, with its enigmatic gardens and architectural prowess, commands high prices due to its cultural significance. Additionally, luxury homes in neighborhoods like Colares, close to beautiful beaches and golf courses, tend to fetch premium prices. Properties with modern amenities, yet historical charm, particularly in prime locations near Sintra's famous palaces, like the Pena Palace and the Moorish Castle, are among the top tier of the real estate market in this picturesque region.
