"The Angel with the Crown of Thorns" (1668-1671) by Giovanni Lorenzo Bernini
Bernini's architectural conceits include the piazza and colonnades of St Peter's. He planned several Roman palaces: Palazzo Barberini (from 1630 on which he worked with Borromini); Palazzo Ludovisi (now Palazzo Montecitorio); and Palazzo Chigi.
Bernini's first architectural project was the magnificent bronze St. Peter's baldachin (1624-1633), the canopy over the high altar of St. Peter's Basilica, and the façade for the church of Santa Bibiana (1624).
Bernini did not build many churches from scratch, preferring instead to concentrate on the embellishment of pre-existing structures. Bernini fulfilled three commissions in the field; his stature allowed him the freedom to design the structure and decorate the interiors in coherent designs. Best known is the small oval baroque church of Sant'Andrea al Quirinale which includes the statue of St. Andrew the Apostle soaring high above the aedicule framing the high altar. Bernini also designed churches in Castelgandolfo (San Tommaso da Villanova) and Ariccia (Santa Maria Assunta).
