Saint Charles at the Four Fountains

Saint Charles at the Four Fountains is a Baroque church in Rome's Monti district distinguished by its oval interior shape and complex geometric design. The dome features hexagonal, octagonal, and cross-shaped patterns, while the walls curve gently to create different spatial levels.

Architect Francesco Borromini constructed the building between 1638 and 1642 for the Spanish Trinitarian Fathers. The facade was completed shortly before his death in 1667 and continues to define the appearance of the site today.

The church displays Borromini's signature through its curved walls and mathematically planned forms that convey the innovative spirit of the Baroque to visitors today. Walking inside, you immediately sense how every element was deliberately arranged to create a particular spiritual effect.

The building sits at a busy square with four fountains that give the place its name and serve as good reference points. Visitors should expect tight quarters since the interior is small and intimate, allowing for a focused experience.

The entire church fits within a space the size of one of the four pillars supporting the dome of Saint Peter's Basilica. This remarkable proportion shows how Borromini achieved maximum impact within minimal space.
