History and Description
The Tempietto di Sant’Andrea was commissioned by Pope Julius III in 1553. The architect was Jacopo Barozzi da Vignola, who along with some peers was also in charge of the simultaneously built Villa Giulia (the current seat of Rome’s National Etruscan Museum).
The Pope had the church built in response to a vow he had made when having been spared during the Plunder of Rome by the Landsknechts in 1527.
Between 1826 and 1830, the dome and interior of the church were restored by Giuseppe Valadier and others. At the time, Valadier was also renovating the nearby Piazza del Popolo.
In 1950, the colorful floor was restored.
A 1977 restoration, in which the dome was clad in bronze, was undone toward the end of the 20th century.
The grayish type of marble called peperino was used for the facade.
