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.

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! 🤩
