About Lisbon

Seven hills, yellow trams, fado drifting from open windows and the ocean nearby. Just 40 minutes by train — fairy-tale Sintra with palaces in the forest.

💡 Fun facts

Pena Palace in Sintra is one of the "Seven Wonders of Portugal".
Sintra was the first place in Europe that UNESCO listed specifically as a "cultural landscape" (1995).
The Initiation Well at Quinta da Regaleira is a spiral staircase about 27 metres deep leading underground.
