The castle of Kelefa is located about halfway between the current village of Kelefa and the Bay of Oitylo. It was built in 1679 by the Ottomans, in order to contain the Inner Mani region. Some years later, in 1685, the Maniots besieged the castle. They sent messengers to Venice so the Doge could send a fleet to help them capture the castle. The Venetians were currently at war with the Ottomans so they agreed and sent a fleet under Francesco Morosini. As soon the fleets bearing the symbol of St Mark the Ottoman garrison surrendered. A year later the Ottomans returned with a strong force and laid siege to the castle but were driven back. Along with the rest of the Peloponnese, the castle remained in Venetian hands for about 30 years, but in 1715 the Ottomans recaptured the Peloponnese. Around 1780 the Ottomans abandoned the castle, which became derelict.
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.
