The Royal Palace of La Granja de San Ildefonso, also known as the Palace of La Granja, is a royal residence located in the town of San Ildefonso, in the province of Segovia, Spain. The palace was originally built in the early 18th century by King Philip V, the first Bourbon king of Spain, as a summer residence for the Spanish royal family.

The palace is set in extensive gardens that are considered some of the finest in Europe. The gardens were designed in the French style by the French architect René Carlier, who worked at Versailles, and are notable for their fountains, ponds, and statues.

The palace itself is a grand example of Spanish Baroque architecture, with ornate facades, sweeping staircases, and sumptuous interiors. The palace has been used for many purposes over the years, including as a royal residence, a museum, and a location for international summits.

Today, the palace and its gardens are open to the public and are a popular tourist attraction. Visitors can explore the palace's lavish interiors, admire the gardens, and see the spectacular fountains in action during the summer months. The Palace of La Granja is a beautiful and historic site that is well worth a visit for anyone interested in the history and culture of Spain.
