Quinta da Regaleira is an estate located near the historic center of
Sintra, Portugal. As beautiful as the estate and the gardens around it
is, with the mysticvGruta do Labirinto (the Labyrinthic Grotto), it’s
mysterious wishing well that is a true atraction. This 27 meter deep
well resembles an inverted tower. Depending on the direction you choose,
either a journey down into the depths of the earth, or a climb out of
the darkness into the light awaits. either way, it is worth the visit.
