Pena Palace
The Pena Palace stands on the second highest peak of the Sintra Mountains and was built by Ferdinand II, king from 1837 to 1853, as a summer residence for the Portuguese royal family. This UNESCO World Heritage Site has Neo-Gothic, Neo-Manueline, Neo-Islamic and Neo-Renaissance influences, making it the epitome of 19th-century Romanticism. Surrounding the palace is an extensive lush garden with more than 500 plant species from all over the world and an incredible labyrinthic system of paths.
