Spinalonga is a barren, arid rocky islet lying in the mouth of the natural harbour of Elounda. The islet was fortified in antiquity, to protect the ancient city of Olous. Towards the end of the 16th century, the Venetians, as part of their great fortification works to defend Crete, built on Spinalonga one of the most important bastion-type seaward fortresses of the Mediterranean. At strategic points in the fortifications are set the two demilunes, major works of fortification architecture.
During the Cretan War (1645-1669), refugees sought shelter on the islet, as did rebels who used it as a base to harrass the Ottomans. Under the terms of the treaty for the surrender of Chandax (Heraklion) in 1669, Spinalonga remained a Venetian possession. In 1715, following a siege, the islet was surrendered to the Ottomans, the Venetian garrison left and the remaining 600 inhabitants were taken captive.
From 1715 onwards, Spinalonga was settled by Muslims, who built their houses on the foundations of the Venetian buildings. The village flourished after the mid-19th century, until by 1881 it housed a population of 1,112 and was the largest Muslim commercial centre of Merabello Bay.
The village houses were arranged in a stepped pattern across the west and south sides of the islet. At the end of the 19th century it is estimated that there were approximately 200 homes and 25 shops or workshops on Spinalonga. Today many well-built two-storey houses and shops remain; their morphology and symmetrical proportions are indicative of the principles of local and Balkan architectural tradition.
In 1904, during the period of the Cretan State, Spinalonga was chosen as the site of a Leper Hospital. Sufferers who were sent to live on the island survived on State funding and charitable donations. Their hard, wretched life did not weaken their will to live. They organised their home, fell in love, married, had children.
After the Leper Hospital was shut down in 1957, the islet remained deserted and uninhabited. In 1976 it was designated an archaeological site. Today it is an organised archaeological site with hundreds of thousands of visitors each year.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
