The fort at Imeri Gramvousa island was built between 1579 and 1584 during Venetian rule over Crete to defend the island from the Ottoman Turks. The fort remained in Venetian hands throughout the prolonged Cretan War, and in the treaty of 16 September 1669, which surrendered Crete to the Ottomans, Gramvousa, along with the fortresses of Souda and Spinalonga, was retained by Venice. These three forts defended Venetian trade routes and were also strategic bases in the event of a new Ottoman–Venetian war for Crete.
On 6 December 1691, during the Morean War (another Ottoman–Venetian war), the Neapolitan Captain de la Giocca betrayed the Venetians by surrendering Gramvousa to the Ottoman Turks for a generous bribe. He lived the rest of his life in Constantinople and was well known by the nickname 'Captain Grambousas'. Not long after the start of Turkish rule, Cretan insurgents used to gather at the three coastal forts which included Gramvousa.
With the outbreak of the Greek War of Independence, the fort fell to the insurgents' hands. In 1823, Emmanouil Tombazis, the Greek provisional government's commissioner for Crete, failed to strengthen the defences at Gramvousa when he had the opportunity, soon after his arrival on the island.
Towards the summer of 1825, a body of three to four hundred Cretans, who had fought with other Greeks in the Peloponnese, journeyed to Crete. On 9 August 1825, led by Dimitrios Kallergis and Emmanouil Antoniadis, this group of Cretans, disguised as Turks, captured the fort at Gramvousa, which became their base. These and subsequent actions revitalized the Cretan insurgency, ushering the so-called 'Gramvousa period'.
Although the Ottomans did not manage to retake the fort, they were successful in blocking the spread of the insurgency to the islands' western provinces. The insurgents were besieged in Gramvousa for more than two years and they had to resort to piracy to survive. Gramvousa became a hive of piratical activity that greatly affected Turkish-Egyptian and European shipping in the region. During that period the population of Gramvousa became organised and they built a school and a church. The church was called Panagia i Kleftrina and was dedicated to the wives of the klephts, namely the pirates.
In 1828, the new Governor of Greece, Ioannis Kapodistrias, sent Alexander Mavrocordatos with British and French ships to Crete to deal with the pirates. This expedition resulted in the destruction of all pirate ships at Gramvousa and the fort came under British control. On 5 January 1828, on Kapodistrias' orders Hatzimichalis Dalianis landed at Gramvousa with 700 men.
Today, Imeri Gramvousa is a popular tourist attraction.References:
Built around AD 90 to entertain the legionaries stationed at the fort of Caerleon (Isca), the impressive amphitheatre was the Roman equivalent of today’s multiplex cinema. Wooden benches provided seating for up to 6,000 spectators, who would gather to watch bloodthirsty displays featuring gladiatorial combat and exotic wild animals.
Long after the Romans left, the amphitheatre took on a new life in Arthurian legend. Geoffrey of Monmouth, the somewhat imaginative 12th-century scholar, wrote in his History of the Kings of Britain that Arthur was crowned in Caerleon and that the ruined amphitheatre was actually the remains of King Arthur’s Round Table.
Today it is the most complete Roman amphitheatre in Britain.
