Sintra

Sintra is one of the most beautiful cities in the world. Only 40 minutes from Lisbon, this city, full of palaces and castles, is a jewel of architecture. The Pena Palace, a beautiful 19th century Renaissance building, has given Sintra the recognition of being a UNESCO World Heritage Site. At that point in time, Sintra was the summer residence of the kings of Portugal, leaving Lisbon due to its hot temperature.
