Oratory of San Giacomo della Marina, Baroque oratory at Mura delle Grazie, Genoa, Italy.

The Oratory of San Giacomo della Marina is a baroque chapel in Genoa decorated inside with twelve large painted canvas works. These paintings cover the walls with scenes depicting the life of Saint James throughout the interior space.

A marble inscription, now lost, recorded that the first oratory was built in 1403; a plaque still in place notes a wall built at the confraternity's expense in 1450. The Romanesque building was completely rebuilt in Baroque style in the first half of the 17th century, when twelve large canvases by leading Ligurian painters were installed. In the 1790s the vault and wall decoration were completed, giving the interior its present appearance.

The oratory belongs to the Confraternita di San Giacomo della Marina, the leading brotherhood of the casaccia, which shared the building and its processions with other confraternities under fixed rules. The name recalls the medieval pilgrims who passed here on their way to Santiago de Compostela. The eleven canvases of the saint's life were commissioned by individual brothers from the foremost Genoese painters of the 17th century.

The oratory stands on the Mura delle Grazie, facing Corso Maurizio Quadrio; only its side facade is visible, with the entrance and five 18th-century windows. Guided visits are available by reservation for groups and associations, so arrange one in advance rather than arriving unannounced.

Among the paintings is a work showing Saint James defeating the Moors, a subject that captures a legendary moment connected to the city's identity. This theme appears repeatedly in Genoese art and shows how deeply this story shaped local consciousness.
