Pena Palace
Few buildings on earth are as immediately arresting as the Palácio da Pena - a 19th-century romantic confection of towers, battlements, domes, and drawbridges painted in shades of ochre, crimson, and gold that blaze against the forest and sky like something conjured from a dream. Built for King Fernando II on the ruins of a Hieronymite monastery, Pena is a joyous architectural fantasy drawing on Gothic, Manueline, Moorish, and Renaissance styles in wilful, exhilarating abundance. Its hilltop position, the highest in the Sintra range, offers views on clear days that stretch from the Tagus estuary to the open Atlantic.
