Historic events for Croatia - the tenth anniversary of accession to the European Union and this year's entry into the Schengen area and the Eurozone - were celebrated in Istanbul with a concert by the top Croatian musicians "Trio Krpan."
The concert took place on December 4, 2023, in the ceremonial hall of Pera Palace, a hotel that, along with the Esplanade Hotel in Zagreb, was part of the Orient Express route, thus connecting Zagreb and Istanbul through time.
