Lithuanian chapels have been operating in the National Shrine in Washington DC and St Peter's Basilica in the Vatican for more than fifty years. There are also chapels in the Church of the Holy Sepulchre of Šiluva. The chapel of the Virgin Mary at the National Shrine of the Immaculate Conception in Washington was consecrated on 5 September 1966, and the chapel of Our Lady of Mercy at St. Peter's Basilica in Vatican City on 7 July 1970. It is rarely thought of today that the appearance of these chapels in two centres of the Western world at the height of the Cold War is tantamount to a miracle. At that time, Lithuania did not exist on the geopolitical map of the world, Catholicism was persecuted and crushed in our country, and the faithful suffered restrictions and repression. This exhibition presents the history of both chapels, revealing their significance for the Lithuanian diaspora and for occupied Lithuania. Particular attention is paid to the artistic contexts that allowed Lithuanian war refugee artists to be integrated into the artistic life of the countries that hosted them, and to express themselves internationally. The story of the Lithuanian chapels in Washington and the Vatican is continued and expanded in two additional parts of the exhibition. One of them is devoted to the modernisation of Lithuanian church art and architecture between the wars. It features works of religious art by national art classics Adamas Galdikas, Petras Rimša, Stasys Ušinskas and other artists.
