La Almudaina is the Royal Palace or Alcázar Real of the city of Palma de Mallorca, in Spain, and one of the residences of the Spanish Royal Family, managed by the public body National Heritage. It collects in its walls the history of the islands from the megalithic settlements.

This imposing fortress, known at the time of the conquest under the name "Zuda", was rebuilt in 1309 by King James II, following the model of the Royal Palace of Perpignan.

In La Almudaina the monarchs of the kingdom of Majorca, those of Aragon and those of Spain had successively their court. Felipe II assigned the "Tinell" to the Royal Court and installed the Captaincy General of the Islands in the rest of the building.

The current structure of La Almudaina corresponds to the one built in the 14th century with its different spaces; the palaces of the King and the Queen, the Chapel of Santa Ana or the baths, are the most prominent.

Its decoration presents two environments. On the ground floor the medieval style is recreated with works from the 15th to the 20th century. The upper floor, used for the celebration of official acts of the Royal Family, is decorated with objects and furniture from other Royal Sites from the 17th, 18th and 19th centuries.

The current castle, of Roman origin, is a modification of the Muslim fortress begun in 1281, it lasted until 1343, during the reigns of Jaime II, son of Jaime I the Conqueror, Sancho I and Jaime III. La Almudaina was the seat of the prosperous Mallorcan kingdom of the 14th century, during the reigns of the aforementioned monarch and of his successors Sancho I and Jaime III, until passing to the Crown of Aragon with Pedro IV in 1349.

During the first half of the 16th century, the upper floor was built by order of King Carlos I of Spain.
