Officially the Chiesa di Santa Maria del Suffragio, this small Baroque church on Via Garibaldi is known to everyone in Monopoli as the Chiesa del Purgatorio. The facade is plastered with carved skulls, crossed bones, and skeletal figures — a memento mori program meant to remind passers-by of the brevity of life and the importance of praying for the dead.
The real curiosity is inside: a crypt with the natural-mummified bodies of members of the confraternity that built the church in the seventeenth century. The chamber is opened only on certain days (typically All Souls and during the patronal festa); the rest of the year you can see the upper church and a small museum of religious objects. Bring a torch — the lighting is theatrical at best.
