In the Roman times the city of Peqin was known by the name of Clodiana, an Illyrian-inhabited territory. The foundations of the castle are thought to date from the Roman period, the time of the construction of the Via Egnatia. Its walls at one point had a height of around 12 metres. The castle was later rebuilt and expanded during the Turkish occupation of Albania, at which time it was passed into the control of the Sipahi (lord) of the local fief, who added a palace and a harem. The last resident of the castle was Demir Pasha.
The castle was equipped with subterranean tunnels which served as exits several km away from the city in difficult times. Similarly, clay pipes have been found in the walls of the castle, which archaeologists believe is an indication that water was supplied from outside the castle during wartime.
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.
