Finding Sant'Ivo alla Sapienza is an adventure in itself. This small church is tucked away, not visible from the street, and requires visitors to enter the courtyard of an old palazzo. Just a block from the lively Piazza Navona, its location remains a secret to many who stroll nearby.
Sant'Ivo alla Sapienza is celebrated as one of architect Francesco Borromini’s finest works. The church often greets visitors with closed doors, making each visit feel rare and special. Its striking dome stands out, designed in the shape of a six-pointed star, reminiscent of the Star of David. However, every other point of the star is gently rounded, creating a unique and harmonious silhouette.
The church's steeple is especially remarkable. From the outside, it appears to have a winding staircase spiraling upward, almost as if it could lead straight to the heavens. Commissioned by the influential Barberini family, who were known for producing several popes, the church also carries a bit of family symbolism. The Barberini’s emblem was the bee, and some say the steeple mimics the stinger of this insect, adding another layer of history and meaning to the structure.
