The exhibition "Returned. The Lost International Treaties of the Republic of Lithuania, 1918–1940" invited visitors to immerse themselves in the fascinating history of the rescue, preservation and subsequent search for international treaties that testify to the recognition of the Lithuanian state, as well as to see these treaties that were long thought to be lost. The international treaties of the Republic of Lithuania, taken from Kaunas, the provisional capital of Lithuania, in 1939, returned in 2021 to Vilnius, the eternal capital of Lithuania, for which so much was fought for, and were exhibited in the restored Palace of the Grand Dukes of Lithuania. It is a symbolic thread linking the statehood of modern and historic Lithuania and underlining the centuries-old traditions of this statehood.
The exhibition catalogue is published in Lithuanian and English.
