San Giuseppe church was erected in 1756-1796 under the patronage of the Benedictine order. The church and an adjacent convent of nuns occupied a site where prior to the 1693 earthquake had been located the church of San Tommaso. The architect is unknown, but in the circle of Rosario Gagliardi. Like many local churches, the façade has three highly sculpted order, decorated with statues of Saints of the Benedictine orders, including Saints Benedict and Mauro above and St Gertrude and Scolastica below. Near the entrance are statues of St Gregory the Great and St Augustine by Giambattista Muccio in 1775. The entrance portals have iron grillwork screens (1774) by Filippo Scattarelli.
The interior has an oval layout, but kept a large choir and coretti situated over the entrance and flanking the nave, where the nuns could hear the mass while remaining cloistered. Over the vault is a fresco depicting the Glory of St Benedict with St Joseph (1793) by Sebastiano Monaco. The walls are elaborately stuccoed (1793) by Agrippino Maggiore and the Cultrera di Licodia Eubea. The altars (19th century) have elaborate scagliola, and have altarpieces by Tommaso Pollace and Giuseppe Crestadoro, depicting the Trinity, St Mauro, St Benedict, and Ste Gertrude. The pavement has white stone and maiolica tiles. The Vestibule has statues depicting St Benedict (17th century) and a silver-coated St Joseph (1785).
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
