4.5 stars and rounded up.
A UNESCO world heritage site, one of the official residences of the Spanish monarchy, this location started as a hunting lodge in the 12th century then came into use for the royal household in the 16th century, with major constructions instigated by Phillip II and V, Ferdinand VI and Charles III.
Today the palace rooms are open to the public as well as a several rooms at the entrance which chronicle the history, design and functional usage shifts of the palace. Compared to other royal residences, the number of viewable rooms are fewer though no less impressive. Highlights are the Salón Árab with its intricate Moorish-inspired carved and painted ceiling and walls, the Gabinete de Porcelana (Porcelain room) covered floor to ceiling with Roccoco chinoiserie motifs of birds, flowers, and Oriental-themed figurines strongly influenced by 18th century Romantic decorative trends. Personally I enjoyed seeing the more casual billiards room and imagining the games played hundreds of years ago. Also cool to see the wedding dresses worn by Spanish queens and princesses in the past century.
The gardens surrounding the palace are fairly expansive and pleasant to walk around, you could easily spend an hour here. There are some fountains and manicured shrubbery, and scenic views along the Tagus River that borders the grounds. There's also a portion of the garden with many peacocks.
Tickets are €9 to self tour the palace rooms. Gardens are free. Like many museums and palaces in Europe, unless you use the lockers (€1 coin operated, returned upon unlocking), they make you carry any larger bags or backpacks on your front rather than on your back. Museum store and bathrooms are available. Plan to spend ~2.5-3 hours here. There are several nearby restaurants with views of the river or more within a 15-20 minute walk closer to downtown. read more
