— — a façade the city left unfinished on purpose.
“The civic church of Bologna, opening onto Piazza Maggiore beneath a brick façade only half-clad in marble. San Petronio was begun in 1390 and never finished, the upper face left raw red brick where the white stone runs out. Inside, the nave is the largest brick-vaulted Gothic interior in the world. A long bronze line crosses the floor — the meridian Cassini set in 1655 — and once a year the noon sun walks straight down it.
Each tile is finished by hand in our Knoxville studio. Artwork is slowly infused into the ceramic surface under high heat and pressure, and rests beneath a thin glossy finish. The colour lives in the surface, not on top of it.

San Petronio fronts Piazza Maggiore in Bologna, dedicated to the city's patron saint and built by the civic commune rather than the church. Construction began in 1390 to a design by Antonio di Vincenzo and continued in fits and stops for more than six centuries. The basilica is roughly 132 metres long and 60 metres wide at the transept, the largest brick-built Gothic church in the world by volume. The lower third of the façade carries Istrian marble; above that the brick remains exposed, a permanent record of the project that ran out of stone.
The remarkable instrument inside is the meridian line laid into the floor by Giovanni Domenico Cassini in 1655 and refined by Eustachio Manfredi in 1695. A pinhole in the high vault throws a disc of sunlight that crosses the bronze strip each solar noon, marking the day of the year with calibrated precision. At nearly sixty-seven metres, it remains one of the longest meridian instruments ever built. Cassini used the line to refine the measurement of the solar year and the obliquity of the ecliptic. On a clear winter noon the disc still walks the bronze.
The basilica opens onto Piazza Maggiore in the centre of Bologna's medieval core and is free to enter through the main door, with smaller charges for the chapels, the terrace, and the small museum. Mornings are quieter; the meridian line is most legible between roughly 10:00 and 13:00 when the sun reaches the vault pinhole. Modest dress is expected. The civic commune still owns the basilica through the Fabbriceria, not the Holy See, an arrangement unusual in Italy and unchanged since 1390. Walking the nave end to end takes a long minute at slow pace.
