Pena Palace
A 19th-century Romanticist masterpiece perched at 500m on the Serra de Sintra, and one of Portugal's Seven Wonders. King Ferdinand II built it on the ruins of a monastery, mixing Gothic, Moorish, Renaissance, and Manueline styles into a unique exterior painted in bold red, yellow, and purple — looking like a castle from a storybook. The interior preserves the original royal furnishings, and the 200-hectare park is filled with exotic plants from around the world. On clear days, views reach Lisbon and the Atlantic. Admission about EUR 14 (park included). Bus 434 or about 45-minute uphill walk from Sintra station.
