An old fortification of the Frankopans, built during the wars against the Turks, Slovin was first mentioned in the 12th century. The old fort was property of the Frankopan family since the 15th century, joined by an old Franciscan monastery from the same period. Later, this town has been called Slunj. In the 16th century the town was ravaged by the Ottoman wars and turned into a military outpost of the Croatian Military Frontier, but by the end of the 17th century the settlement was rebuilt into the Slunj as it exists today. The castle has been developed to a fortress and served as headquarters for the commanding general of this area.
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.
