Ah, Sintra! So renowned for its stunning palaces, both inside and out, both royal and not. But is it worth going inside them? Here are some that are definitely worth visiting for their interior beauty. 

1. Palácio Nacional de Sintra (Sintra National Palace): This historic royal palace features a unique blend of architectural styles and boasts beautifully decorated rooms, including the Sala dos Brasões (Coat of Arms Room) and the Sala dos Cisnes (Swan Room). Don't miss the intricate tilework in the Cozinha dos Cisnes (Swan Kitchen). It is a trip through Portuguese history.

2. Palácio da Pena (Pena Palace): Perched atop a hill, Pena Royal Palace is a colorful and eclectic 19th century masterpiece. Inside, visitors are treated to richly decorated rooms adorned with ornate furnishings, tapestries, and paintings from the last dynasty of royals. The Arab Room, with its intricate Moorish-inspired design, is breathtaking. Well worth a visit, but don't call it "Peña."

3. Quinta da Regaleira: While not a traditional palace, Quinta da Regaleira is a magical estate with enchanting gardens and a mysterious underground network of tunnels and caves. Inside the main house, visitors can explore lavishly decorated rooms filled with symbolism and intrigue. One of a kind!

4. Palácio de Monserrate (Monserrate Palace): Monserrate Palace is known for its exotic architecture and lush botanical gardens. Inside, visitors can admire the intricate plasterwork, stunning stained glass windows, and a collection of beautiful tiles.

And, why not stay at a palace! The Valverde Seteais Palace Hotel  stands as a remarkable example of neoclassical architecture. Its grandeur and historical significance make it a luxurious retreat. 

Or, explore the empty Castle of the Moors is a treat for  both the architectural design  and the strategic significance of its builders, the Moors, during their occupation of the Iberian Peninsula. It commands awe-inspiring views of the surrounding landscape, serving as a tangible reminder of Portugal's rich and complex history. Built in the 8th and 9th centuries, the castle played a role in the region's defense during the Reconquista. Its restored walls and strategic location made it a key stronghold up to the  fall of Lisbon in 1147. Today, visitors can explore the castle's ramparts, towers, and ruins, and enjoy the view.
