Temple of San Miserino, Roman temple in San Donaci, Italy.

Temple of San Miserino is an early Christian structure with an octagonal form set within a square measuring about 7.65 by 7.30 meters (25 by 24 feet), covered by a lowered concrete dome. The interior holds four semicircular and two rectangular niches, with a floor mosaic made of dark and white stone pieces arranged in geometric patterns.

The building's roots stretch back to the 1st century CE, as uncovered by archaeological work in the 1970s. Mosaics from the 2nd century and later Early Christian additions show how the site remained in use through the 6th century.

The name San Miserino is attached to a rural church converted from an older building; medieval frescoes in red survive on the walls, and the capitals carry stucco acanthus scrolls dated to the 6th century. The site lies beside the Limitone dei Greci, a boundary line that the road via ad Lippium may have followed toward Lecce.

The structure stands along the ancient Via ad Lippium, a historic road that once linked Oria and Lecce across the Salento peninsula. You can walk this old route and explore the countryside surrounding the site.

The temple's mosaic floor displays a rare pattern of dark and white stones that has remarkably survived the passage of centuries. This crafted detail reveals the high quality of the original construction and workmanship.
