The Temple of San Sebastiano is a late-Renaissance- or Mannerist-style church in central Milan.
The cylindrical church is shaped like a can capped with a dome. The octagonal church was commissioned in 1576, after the end of a season of plague, dedicated to St Sebastian. The non-linear layout is atypical for post-Tridentine churches. Perhaps the site, which had housed an earlier medieval church or sanctuary dedicated to San Quilino, dictated the shape.
