The first written mention of Íscar was in the year 939 AD in Muslim chronicles. The remaining Christians reconquered Iscar in 1086 AD. Build on the ruins of its ancient fortress, Iscar’s Castle stands majestic looking over the village. The oldest preserved parts of this fortress (probably dating back to the 13th century) are remains of the curtain wall and the inside structure of the tower. To provide a defence against possible attacks from the west side, weak point, the enclosure was re-enforced in the second halfof the fifteenth century for defensive purposes.
At the back of the Main Tower, a large defensive spur, flanked by two turrets transformed the ground floor into the shape of a pentagon.In this side also a new body was added as a defensive barbican, with a small artillery barrier with three circular barrel turrets. And for safety a Moat was dug into the limestone rocks whose access was by a drawbridge.
On one of these turrets appears the shield of Pedro de Zúñiga y Avellaneda and his wife Catalina de Velasco y Mendoza, IICounts of the Miranda del Castañar, which dates this work at between 1478 and 1493.
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.
