The Sintra National Palace, also known as Palácio da Vila, is one of Portugal's most iconic monuments and the oldest royal palace in the country. Located in the historic center of Sintra, it is easily recognizable by its two large, white, conical chimneys, nearly 33 meters high, visible from many points in the city.

It was originally a Hieronymite monastery founded in the 16th century, dedicated to Our Lady of Sorrow. After the 1755 earthquake, it fell into ruins and was acquired by King Ferdinand II in 1838. Between 1842 and 1854, it became a summer palace for the Portuguese royal family. In 1910, following the end of the monarchy, it passed into state hands and was opened to the public.

I didn't visit the Palacio National de Pene because the €20 entrance fee is tied to a time slot and you should be there about an hour before the gate opens so you don't miss your time slot. It was too stressful for me 🤔🙂 The Parque de Pene is simply stunning! I bought the entrance ticket (€12) at the Castelo, but you can also buy them separately in the entrance area on site. When you're there, you should leave the wide main paths and follow the narrow, enchanted paths to the individual highlights - the view from Cruz Alto (The Cross) is magnificent! 🤩

The Quinta da Regaleira palace was built at the beginning of the 20th century by the millionaire Antonio Augusto Carvalho Monteiro (1848-1920), who fulfilled his dream here with the help of the theater architect Luigi Manini (1848-1936). It is a UNESCO World Heritage Site. A fairytale 🏰. Beautiful here 🥰.
