Palacio de Ayete

Palacio de Ayete in San Sebastián, Spain, is a 19th‑century residential palace built for Spanish aristocrats, the Dukes of Bailén, and executed in a neoclassical‑inspired manner. Erected in 1878 as a summer retreat, it quickly became part of the social and political life of the city because of its use by members of the Spanish royal family and later by the national government.

Work completed in 1878 produced a country house intended for seasonal use by its noble owners. Nine years after completion the municipal council attempted to acquire the property in order to offer it to the queen regent Maria Christina as a summer residence. During the late 19th century the building hosted royal personages: it served as a residence for Isabella II, Alfonso XII, Maria Christina and Alfonso XIII until the Miramar Palace was built in 1893. On 27 March 1889 the palace received Queen Victoria of the United Kingdom as a guest.

Through inheritance the house formed part of the Basa family’s dowry from the Travesedo marriage. The family vacated the building in 1939 because of the Spanish Civil War and relocated to Ondarreta, to a villa then known as Villa Emilia and later called Itxas‑ertz. In 1940 the heirs of the previous owner sold the property to the city council. The municipality passed it on to the Head of State, and Francisco Franco used the palace as his August residence from 1940 until 1975; national Councils of Ministers met there during that period. From the palace Franco left for his trip to Hendaye to meet Adolf Hitler, and in its salons he decided on a policy shift toward the United States.

After the Franco years the city undertook rehabilitation of the interior. The building now functions as a civic centre for peace and human‑rights work and the gardens and palace were formally protected as a Cultural Asset in the category of Monumental Ensemble by the regional government, the designation published in the official regional gazette on 13 November 2006. On 17 October 2011 the site hosted the International Peace Conference of San Sebastián (Aiete), attended by international figures including Kofi Annan, Bertie Ahern, Gro Harlem Brundtland, Pierre Joxe, Gerry Adams and Jonathan Powell, together with representatives of Basque political parties (Basque Nationalist Party, PSE, Eusko Alkartasuna), trade unions (ELA, LAB, UGT, CCOO) and major French parties (Union for a Popular Movement, Socialist Party, Democratic Movement).
