The region of Sintra, Portugal has always been surrounded by a mystical aura. In Roman times, people of the region built a temple dedicated to Cinthia, the goddess of the moon. Ultimately, the entire region was baptized with a derivation of that name: Sintra.
“Since the beginning of recorded time, Sintra has been regarded as a land cloaked in mysticism. It permeates its steep hillsides and even its air. It’s common to be surrounded in nevoeiro (fog) one moment and the next, bathed in sunlight. You can feel a bigger, stranger power at work in those hills. Its legends have been passed orally through generations and have survived since the time of the Moors — and maybe even before then.”
