Gonio fortress (previously called Apsaros, or Apsaruntos), is a Roman fortification in Adjara, at the mouth of the Chorokhi river. The oldest reference to the fortress is by Pliny the Elder in the Natural History (1st century AD). There is also a reference to the ancient name of the site in Appian’s Mithridatic Wars (2nd century AD). In the 2nd century AD it was a well-fortified Roman city within Colchis. The town was also known for its theatre and hippodrome. It later came under Byzantine influence. The name 'Gonio' is first attested in Michael Panaretos in the 14th century. In addition, there was a short-lived Genoese trade factory at the site.
In 1547 Gonio was taken by the Ottomans, who held it until 1878, when, via the San-Stefano Treaty, Adjara became part of the Russian empire. In the fall of 1647, according to Evliya Çelebi, Gonio was captured by a Cossack navy of 70 chaikas, but quickly recovered by Ghazi Sidi Ahmed, ruler of the Tortum sanjak, with a force of 1,000 Turks and 3,000 'Mingrelians'.
The grave of Saint Matthias, one of the twelve apostles, is believed to be inside the Gonio fortress. However, this is unverifiable as the Georgian government currently prohibits digging near the supposed gravesite. Other archaeological excavations are however taking place on the grounds of the fortress, focusing on Roman layers.References:
The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians. The county became a privileged refuge for persecuted Cathars.
The castle, often besieged (notably by Simon de Montfort in 1211 and 1212), resisted assault and was only taken once, in 1486, thanks to treachery during the war between two branches of the Foix family.
From the 14th century, the Counts of Foix spent less and less time in the uncomfortable castle, preferring the Governors' Palace. From 1479, the Counts of Foix became Kings of Navarre and the last of them, made Henri IV of France, annexed his Pyrrenean lands to France.
As seat of the Governor of the Foix region from the 15th century, the castle continued to ensure the defence of the area, notably during the Wars of Religion. Alone of all the castles in the region, it was exempted from the destruction orders of Richelieu (1632-1638).
Until the Revolution, the fortress remained a garrison. Its life was brightened with grand receptions for its governors, including the Count of Tréville, captain of musketeers under Louis XIII and Marshal Philippe Henri de Ségur, one of Louis XVI's ministers. The Round Tower, built in the 15th century, is the most recent, the two square towers having been built before the 11th century. They served as a political and civil prison for four centuries until 1862.
Since 1930, the castle has housed the collections of the Ariège départemental museum. Sections on prehistory, Gallo-Roman and mediaeval archaeology tell the history of Ariège from ancient times. Currently, the museum is rearranging exhibits to concentrate on the history of the castle site so as to recreate the life of Foix at the time of the Counts.
