Sanctuary of Sant'Oronzo fuori le mura, Religious shrine in Lecce, Italy.

The Sanctuary of Sant'Oronzo fuori le mura is a neoclassical church of Lecce stone standing in a walled garden beside the Tangenziale, near via Adriatica. Its facade has a single tympanum-topped portal framed by four Corinthian pilasters, with a Latin inscription on the entablature dedicating it to the saint's martyrdom. A plain dome crowns the building, visible from the surrounding countryside; inside, the plan is a Greek cross.

A chapel stood here from 1655, built over an earlier one; construction was interrupted by the 1656 plague in Naples and the building later fell into ruin. The present church was built between 1889 and 1910 to designs by Gaetano Capozza, promoted by bishop Gennaro Trama, and restored in 1968 under bishop Francesco Minerva. It reopened for worship only in 2007.

Locals call the sanctuary "La Chesia te la Capu te Santu Ronzu" (the church of the head of Saint Oronzo), recalling the tradition that his severed head rolled into a cistern a few metres away. On 25 August, the second day of Lecce's patronal festival, the archbishop celebrates a morning Mass here, after which the faithful pray at the stone column marking the martyrdom. Since a few years, a procession in October follows Via Adriatica with the saint's statue, stopping at each of the nine chapels.

The site is reached by walking a path marked by nine small chapels that serve as stations leading to the main sanctuary. Visitors should allow time to walk the full route and observe the chapels along the way.

A stone column in the sacred enclosure marks the spot where, by tradition, Oronzo and Giusto were beheaded at dawn on 26 August 68 AD; a few metres away stands a cistern where the saint's severed head is said to have rolled. The church keeps a papier-mâché statue of Oronzo and a sculpture of his head in a glass urn.
