Charenza, also Karentia or Karenz, was a medieval Slavic burgwall on the island of Rügen in the Baltic Sea. It was the administrative centre of the Rani tribe and of the Principality of Rugia. Today, the remnants are called Venzer Burgwall. Charenza was not only the administrative hub of the Rani tribe, but also a religious centre with the temples of Rugievit, Porevit and Porenut. The main religious centre of the Rani, however, was Arkona on Wittow.
In 1168, King Valdemar I of Denmark and his archbishop Absalon captured Arkona. Charenza surrendered a few days later after negotiations with the Rugian princes Tetzlav and Jaromar I. The temples were destroyed, the princes agreed to become Danish vassals and the population adopted the Christian faith. In 1180, the administrative centre of the Principality of Rugia was moved to Rugard (today Bergen auf Rügen, just a few kilometres to the southeast).
In the 12th century, Charenza was mentioned by Saxo Grammaticus and Helmold von Bosau. The last records are from the early 13th century. When the Danish king raised money to build 12 churches on Rügen, one of them was the capelle nostre in Charenz, which in 1232 was granted the village of Gagern as a fief. In 1234, when the Rugian prince Vitslav I granted Lübeck law to Stralsund, the document was signed in Charenza. The last record mentioning Charenza was in 1237. In the 14th century, 'Gharense' was mentioned as belonging to the parish of Gingst.
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.
