Oratory of Saint Mercury
It was built in 1557 and after six years the sculptor Giacomo Serpotta started to work on its decorations. He was very young but already able to perfectly sculpt masks and shields on the 2 small portals. Among his sculptures you can notice a little dragon leaning from the bottom of a crown. The lateral putti are not as perfect in the proportion as the ones in the other oratories but still they are beautiful and worth it to see. Also the splendid floor made with majolica in 1714 and 1715 by Sebastiano Gurrello and Maurizio Vagolotta is one of the very fewest remaining in a sacred place in Palermo.The choir and the seats for the monks are hand-made of wood and they are of the second half of the 18th century.
