Cappella dei Martiri di Otranto

The Chapel of the Martyrs stands behind the high altar of Otranto Cathedral. Seven marble reliquary cases hold the remains associated with the inhabitants killed after the Ottoman capture of the city in 1480; Antonio Primaldo and his companions were canonized in 2013.

Why it matters

The chapel is Otranto's principal memorial to the executions that followed the city's fall. Historical accounts describe the remains being gathered the following year and brought to the cathedral. The number is conventionally given as 800, while the canonized group is identified by the Church as 813. The right apse was enlarged in 1482, and the chapel's later Baroque arrangement is associated with Archbishop Francesco Maria De Aste.

What to notice

The seven marble cases follow the curve of the apse behind the altar. Their arrangement makes the relics the focus of the space, while the chapel's later decoration belongs to the cathedral's Baroque transformation. The room forms part of a wider cathedral complex whose medieval mosaic floor and crypt preserve other layers of Otranto's history.

Context and history

The Ottoman fleet arrived off Otranto in July 1480, and the city fell after a fifteen-day siege. Accounts of the episode record that Antonio Primaldo was among the first executed in August. The remains were later gathered on the hill of Minerva and transferred to the cathedral under the authority of Duke Alfonso of Aragon. The chapel's history spans this immediate memorial and its later architectural development: the apse was enlarged in 1482, while De Aste established the chapel's Baroque setting at the end of the seventeenth century. In 2013 the Church canonized Antonio Primaldo and his 812 companions.
