Príncipe Pío, Mountain in western Madrid, Spain.

Príncipe Pío is a hill on Madrid's western edge that rises above the city and offers views toward the capital and surrounding region. It has several walking paths leading to different viewpoints along its slopes.

The hill was originally part of the Florida estate, bought in 1647 by Francisco de Moura, who built a palace at its foot. It passed to the Pío de Saboya family, and the southern slope became known as Montaña del Príncipe Pío after Isabel María Pío de Saboya inherited it in the late 18th century. In 1792 Charles IV incorporated the estate into the Real Sitio de la Florida, and in 1831 the Infante Francisco de Paula turned the hill into a public park. In 1808, 43 people were shot here by French troops and buried in the nearby Cemetery of La Florida.

The name comes from the Pío de Saboya family, into which Isabel María Pío de Saboya brought the estate at the end of the 18th century. The executions of 2–3 May 1808 are remembered at the nearby Cemetery of La Florida, and Goya's The Third of May 1808 has traditionally been linked to the site, though the Prado notes the setting is disputed.

You can explore the hill on foot by following different paths that lead to various viewpoints across the slopes. It is accessible throughout the day for walking at your own pace.

Military barracks that once stood here were demolished and replaced by the Temple of Debod, an Egyptian temple transported stone by stone from the Nile. This ancient Egyptian structure now sits at this strategic point in Madrid.
