Sant'Ivo alla Sapienza (the church of Sant'Ivo (patron saint of lawyers) in the courtyard of the old Sapienza University. Via del Corso building complex whose courtyard Giacomo della Porta designed in 1575 and whose church Borromini built between 1643 and 1660 for the successive popes Urban VIII (Barberini), Innocent X (Pamphilj), and Alexander VII (Chigi)): the most geometrically complex single building in Roman Baroque architecture and, in the specific judgement of the architectural historian Anthony Blunt (1979), "the most daring and original piece of Baroque architecture in Rome." The specific Sant'Ivo spatial program: the hexagonal plan (the six-pointed star formed by overlapping two equilateral triangles) whose alternating concave and convex bays (the concave semicircular apses at three alternate vertices, the convex tower projections at the three remaining vertices) create the specific undulating wall movement that flows continuously from the pavement to the dome without the conventional Baroque interruption of the cornice.
The spiral lantern (the specific Sant'Ivo exterior element that makes the building immediately recognizable in the Rome skyline, the spiral ramp winding around the exterior of the cylindrical lantern above the dome, terminating in the iron crown and cross): the spiral lantern iconography has been interpreted as the Tower of Babel (the specific biblical architecture of divine overreach that Borromini inverts into a symbol of divine aspiration ascending toward God), as a bee's sting (the Barberini bee heraldry of Urban VIII translated into the specific architectural form of the lantern tip), and as a barber's pole (the popular nickname for the spiral that the Roman street vernacular applied to the Sant'Ivo lantern visible above the surrounding buildings). Open Sunday 9:00-12:00 only (the specific limited access that makes the Sant'Ivo visit one of the most scheduling-dependent in Rome). Free.

Sant'Ivo alla Sapienza: Interior, Dome, and the Sunday Visit
The Interior and Dome
Sant'Ivo alla Sapienza interior (the specific spatial experience, the entry from the Della Porta courtyard through the convex-façade entrance into the six-pointed-star plan whose walls curve alternately inward and outward, the dome beginning immediately above the cornice level without the drum transition that the standard Roman Baroque dome requires): the dome (the specific Borromini solution, the dome that transitions from the star-hexagon plan through a hexagonal drum to the circular lantern base, each transition achieved by the specific Borromini device of the "pandentive" (the curved surface that bridges from the hexagon to the circle without the classical pendentive)): the interior white-stucco surfaces (Borromini's specific choice, no color, no gilding, no marble, just the geometric white space whose complexity emerges from the structural relationships rather than from applied decoration): the specific effect (the Sant'Ivo interior as the most pure expression of Borromini's architectural thought, unmediated by the patron's requirement for iconographic display that the major Jesuit churches imposed).
The Barberini, Pamphilj, and Chigi Program
The Sant'Ivo heraldic program (the three papal coats of arms incorporated into the church decoration, the Urban VIII Barberini bees (the six-pointed star plan itself is interpreted as a stylized Barberini bee), the Innocent X Pamphilj dove, and the Alexander VII Chigi mountains and cross): the Sant'Ivo is simultaneously a building project spanning three pontificates and a heraldic document of 17th-century papal succession, the specific architectural narrative (the building that began under one pope, continued under the next, and was completed under a third, each pope requiring the insertion of his family emblem into the surviving work) is the most politically layered single Borromini commission and the one that most directly represents the specific economic and political conditions of mid-17th-century Roman architecture.
Q&A: Sant'Ivo alla Sapienza
Is Sant'Ivo alla Sapienza worth the Sunday-only restriction?
Yes emphatically, the Sant'Ivo alla Sapienza interior is the single most spatially original room in Baroque Rome, the building that professional architects visit specifically to experience the Borromini spatial vocabulary in its purest form. The Sunday-only opening (9:00-12:00) requires planning: arrive by 9:15 for the minimum queue (the Sant'Ivo Sunday opening draws a mixed audience of the architecture-knowledgeable and the simply curious, the queue at 10:00-11:00 can be 30-40 people, with the visit cycle of approximately 10 minutes per group creating the specific queue experience). The courtyard (the Della Porta 1575 court visible from the street at all hours, the Sant'Ivo convex façade closing the courtyard axis is visible through the gate even when the church is closed): the external Sant'Ivo experience (the spiral lantern above the Roman roofline, the courtyard façade) is always available. The interior requires the Sunday 9:00-12:00 window.
