Ribnica is an Ottoman fortress, located in the Stara Varoš neighborhood of Podgorica, the capital city of Montenegro. The fortress was built in late 15th century (around 1477), during the period of Ottoman reign. It was built above the confluence of Ribnica and Morača rivers, and was one of two fortresses surrounding Stara Varoš.
For a long time, Depedogen was used as an ammunition warehouse. It was severely damaged in 1878, when a thunder strike triggered an explosion which destroyed a large part of the fortress's interior and exterior.
A legend commonly told by the Serbian Orthodox Church leaders says that the fortress stems from the 12th century, and that it's the birthplace of Stefan Nemanja - the founding father of the Nemanjić dynasty. Therefore, a lot of people call the fortress Nemanjin Grad or Nemanjića Grad (Nemanja's Town) and Orthodox ceremonies are often held at the location.

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.
