The foundation of the castle on the island of Pantelleria can possibly traced back to the Arab or Byzantine period in Sicily, even if it is not attested with certainty before the 13th century.
The Castello Barbacane is located in the centre of Pantelleria town at the entrance of the old harbour and is accessed via a staircase from the Via Castello. It was a bulwark to protect the maritime trade of the island, facing the harbour on one side and walls lapped by the sea on the other side. Until just over a century ago, the castle was the predominant element of the walled city
The castle is well preserved and worth a visit.
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.
