Transformation is a word to describe this walk and drive tour. Why? Because during this fantastic day you will learn a little bit about the history of Sintra and also how it used to live the King's from one of the Biggest Empires on earth during the XV & XVI century!
Before you go home search in google, maritime territory Portuguese miles. Bigger than 50 000 km2.
Don't forget, the Portuguese are nice and respectful people, always say Bom dia when you enter in a place with a smile :)
