Sant'Andrea in Via Flaminia
Sant'Andrea in Via Flaminia () is a Roman Catholic church dedicated to St Andrew the Apostle in Rome, Italy. The edifice is also known as "Sant'Andrea del Vignola", after its architect Giacomo Barozzi da Vignola. It was commissioned by Pope Julius III, to commemorate Pope Clement VII’s escape from prison following the Sack of Rome, 1527. The small church on the Via Flaminia, scarcely more than a chapel, was designed by Giacomo Barozzi da Vignola in 1552 and completed the following year, while Vignola was also employed by Julius nearby at the Villa Giulia. Sant'Andrea was  the first church with an elliptical dome and the first step toward the Baroque world of elliptical forms. Interior. The interior space is vividly expressed on the exterior. The "tempio" as it was long called, is an unadorned cube with a dentilled cornice without a frieze, surmounted by an elliptical low dome masked by a high plain drum with a comparable frieze, all in the gray pietra serena more usual to Tuscany than Rome. Applied to the street front is an extremely flat pedimented temple front, whose unadorned frieze is continued alone round the sides of the building, dividing the  cube in the proportions 2:3. Very flat Corinthian pilasters, doubled at the corners, divide the applied facade in three bays, with shell-headed niches flanking the door. Inside there are frescoes by Girolamo Siciolante da Sermoneta and Pellegrino Tibaldi. Julius had the church engraved, plan, elevation and in perspective (G. Vasi 1761). After being long neglected, the unadorned geometry of the structure began to have an appeal to the popular Neoclassical style. The church was refurbished by the neoclassic architect Giuseppe Valadier, during the Napoleonic occupation of Rome, 1805.
