In medieval Georgia, the area of modern-day Abastumani was part of the district of
Odzrkhe so named after a fortress whose ruins survive near the townlet. In the 16th century, it fell to the
Ottoman Empire under whose rule the area was deserted, but its
hot springs were appreciated and frequented by locals. Under the
Russian rule, a short-lived
German colony of Friedenthal () emerged there in 1842. In the 1850s, it was recolonized by the Russians under the patronage of
Viceroy of the Caucasus Mikhail Vorontsov. The new settlement acquired the name Abbas-Tuman after a
nearby located village and became popular for its climate and thermal waters. Its development as a resort is chiefly associated with
Grand Duke George Alexandrovich (1871–1899), a member of the
Russian imperial family, who had retired there due to his ill-health. Abastumani acquired the status of an
urban-type settlement (Georgian:
daba) under the Soviet Union in 1926. Tourism infrastructure has been renovated since the mid-2000s.
Airspace closure Bidzina Ivanishvili, billionaire founder and honorary chairman of
Georgian Dream, began acquiring property in Abastumani in 2018 and subsequently announced plans to redevelop the resort, including a proposed transition to electric-vehicle-only transport. According to
Transparency International – Georgia, nine entities linked to Ivanishvili purchased 52,443 m² of land in the town for 6.4 million
GEL between 2018 and 2022, during which period the state also spent approximately 250 million GEL on resort-area projects, including a controversial bypass road that required the clearing of protected coniferous forest. Ivanishvili and associated companies reportedly own the only helicopter landing pad in the area. In parallel, airspace above Abastumani has been progressively restricted. An 8-kilometre "temporary" closure introduced in October 2019 was later made permanent as zone "Abastumani-1" (UGR-24), and in February 2026 the government enacted Resolution №52, establishing the 52-kilometre-diameter "Abastumani-2" (UGR-58) zone effective 16 April 2026. The ground-to-unlimited (GND-UNL) restriction, formally justified by the needs of the
Abastumani Astrophysical Observatory, affects several major international air corridors connecting
Europe with
Central Asia and is stricter than restrictions applied over Georgia's own military and strategic sites. A 2026
Radio Free Europe/Radio Liberty investigation, citing sources in state aviation bodies and the industry, reported that the expansion was linked to Ivanishvili's interests rather than to observational requirements, noting that the observatory's director was unable to cite any comparable international precedent for the measure. == Spa ==
