Apollonia was an ancient Greek city located on the right bank of the Vjosë river. Apollonia was founded in 588 BCE by Greek colonists from Corfu and Corinth, on a site where native Illyrian tribes lived, and was perhaps the most important of the several classical towns known as Apollonia.
Apollonia flourished under Roman rule and was noted by Cicero in his Philippicae as magna urbs et gravis, a great and important city. Christianity was established in the city at an early stage, and bishops from Apollonia were present during the First Council of Ephesus (431) and the Council of Chalcedon (451).
Its decline, however, began in the 3rd century AD, when an earthquake changed the path of the Aoös, causing the harbour to silt up and the inland area to become a malaria-ridden swamp. The city became increasingly uninhabitable as the inland swamp expanded, and the nearby settlement of Avlona (modern-day Vlorë) became dominant. By the end of antiquity, the city was largely depopulated, hosting only a small Christian community. This community (which probably is part of the site of the old city) built on a nearby hill the church of the Dormition of the Theotokos, part of the Ardenica Monastery.References:
Goryōkaku (五稜郭) (literally, 'five-point fort') is a star fort in the Japanese city of Hakodate on the island of Hokkaido. The fortress was completed in 1866. It was the main fortress of the short-lived Republic of Ezo.
Goryōkaku was designed in 1855 by Takeda Ayasaburō and Jules Brunet. Their plans was based on the work of the French architect Vauban. The fortress was completed in 1866, two years before the collapse of the Tokugawa Shogunate. It is shaped like a five-pointed star. This allowed for greater numbers of gun emplacements on its walls than a traditional Japanese fortress, and reduced the number of blind spots where a cannon could not fire.
The fort was built by the Tokugawa shogunate to protect the Tsugaru Strait against a possible invasion by the Meiji government.
Goryōkaku is famous as the site of the last battle of the Boshin War.
