Sukhumi is a city on the Black Sea coast, on the Soviet Riviera. It is the capital of the unrecognised Republic of Abkhazia, which has controlled it since the 1992–93 war in Abkhazia, although most of the international community considers it legally part of Georgia. Sukhumi’s history can be traced back to the 6th century BC, when it was settled by Greeks, who named it Dioscurias. During this time and the subsequent Roman period, much of the city disappeared under the Black Sea. The city was named Tskhumi when it became part of the Kingdom of Abkhazia and then the Kingdom of Georgia. Contested by local princes, it became part of the Ottoman Empire in the 1570s, where it remained until it was conquered by the Russian Empire in 1810. Following a period of conflict during the Russian Civil War, it became part of the independent Georgia, which included Abkhazia, in 1918. In 1921, the Democratic Republic of Georgia was occupied by the Soviet Bolshevik forces from Russia. Within the Soviet Union, it was regarded as a holiday resort. As the Soviet Union broke up in the early 1990s, the city suffered significant damage during the Abkhaz–Georgian conflict. The present-day population of 60,000 is only half of the population living there towards the end of Soviet rule.
Sukhumi is located on a wide bay of the eastern coast of the Black Sea and serves as a port, rail junction and a holiday resort. It is known for its beaches, sanatoriums, mineral-water spas and semitropical climate. Sukhumi is also an important air link for Abkhazia as the Sukhumi Dranda Airport is located nearby the city. Sukhumi contains a number of small-to-medium size hotels serving chiefly the Russian tourists. Sukhumi Botanical Garden was established in 1840, one of the oldest botanical gardens in the Caucasus. The city has a number of research institutes, the Abkhazian State University and the Sukhumi Open Institute. From 1945 to 1954 the city’s electron physics laboratory was involved in the Soviet program to develop nuclear weapons. Additionally, the Abkhaz State Archive is located in the city. The city is a member of the International Black Sea Club.
Sukhumi houses a number of historical monuments, notably the Besleti Bridge built during the reign of queen Tamar of Georgia in the 12th century. It also retains visible vestiges of the defunct monuments, including the Roman walls, the medieval Castle of Bagrat, several towers of the Kelasuri Wall, also known as Great Abkhazian Wall, constructed between 1628 and 1653 by Levan II Dadiani to protect his fiefdom from the Abkhaz tribes; the 14th-century Genoese fort and the 18th-century Ottoman fortress. The 11th century Kamani Monastery (12 kilometres (7 miles) from Sukhumi) is erected, according to tradition, over the tomb of Saint John Chrysostom. Some 22 km (14 mi) from Sukhumi lies New Athos with the ruins of the medieval city of Anacopia. The Neo-ByzantineNew Athos Monastery was constructed here in the 1880s on behest of TsarAlexander III of Russia. Northward in the mountains is the Krubera Cave, one of the deepest in the world, with a depth of 2,140 meters.
