Isolated on the top, in one of the peaks of the Sintra Hills, the Moorish Castle is a fortification that was founded during the muslim occupation of the Iberian Peninsula, probably in the 10th century.
Its famous walls snake across the hills with their granite blocks interlinking boulders and cliffs.Its wall walk provides stunningly unique views out over the town, the Palace of Pena and, further in the distance, the greens of these hills contrast with the blues of the Atlantic Ocean.
