Few places in the world can envoke a sense of magic and mystery as does Sintra.  From  magical forests to romantic palaces Sintra never fails to seduce.  One of the true gems of this village is the Quinta de Regaleira.  Part of the Cultural Landscape of Sintra under UNESCO, the palace and gardens are trully deserving of a visit.  While walking from the village square you reach the quinta in a few short minutes.  The manor house is trully impressive from the outside. The manueline/gothic architecture is awe inspiring, but the magic of the estate lies within the gardens.  Give yourself time to explore the lakes, statues, initiation well, grotos, and towers; it looks like something out of the garden of eve. Make sure to bring a flashlight as this will enhance the experience when you investigate one of the many grotos.  If you're lucky, it will gently rain and thunder while you are there.  It certainly adds a level of mystery to it all.
