Adria Cathedral (Duomo di Adria) replaced the much older former cathedral nearby, dedicated to Saint John, which continues in use as a parish church. The new cathedral, dedicated to Saints Peter and Paul, was built in the early 19th century over a 14th-century church. When works were undertaken in 1830 to investigate the stability of the foundations, a Byzantine crypt and frescoes were discovered.
The cathedral also contains a Byzantine bas relief of the 6th century, a Byzantine altar and crucifix, and in the sacristy some magnificently carved cupboards by Jacopo Piazzetta from the Charity School of Venice.
Behind the building a replica of the Grotto of Lourdes was constructed in the 1930s, which still attracts many visitors.
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.
