The church of San Pietro in Montorio is located on the square of the same name on the slope of the Janiculum hill. The first mention of the church dates back to the 9th century, but in 1472, under Pope Sixtus IV, the temple was rebuilt. The Pope willingly attracted funds from foreign kings for the restoration of the complex. In particular, among the patrons was the King of France Louis XI, as well as the Spanish kings Isabella and Ferdinand, who ordered the construction of the Little Temple of Bramante.
The Church of San Pietro in Montorio has a rather modest appearance, but a richly decorated interior. The chapels of the temple are decorated with frescoes by Sebastiano del Piombo and Baldassare Peruzzi. In 1876, the royal court of Savoy sold the temple complex to Spain. The complex still belongs to the Spanish state, where the Royal Spanish Academy in Rome was located in the buildings of the monastery.
