The Basilica of the Holy Mother of God Eleusa is a former monastery church situated in the UNESCO World Heritage town of Nesebar in Bulgaria.
The church, on the northern side of the peninsula, was built in the 6th century. It is recorded until the 14th century, and formed part of a monastery complex. It is presumed to have been destroyed by an earthquake.
The northern part and the central nave had sunk into the sea, but in 1920 excavations and research began here, and the church is now well-preserved and partly restored.
It has three naves, three apses and a narthex, with two smaller apses on the north and south sides. It is 28 m long and 18 m wide.

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.
