Originally constructed in the early 19th century, this stunning neoclassical palace served as the Portuguese royal residence from 1860 until the monarchy came to an end in 1910. Visitors can explore the lavish private apartments, state rooms and Queen's chapel, which houses Portugal's only painting by El Greco. Marvel at the exquisite artworks and gilded furnishings that have been around for five centuries. To get to the palace, visitors can take a long uphill walk from Belém, or take tram 18E or bus 760 from Praça do Comércio in the downtown area.
