The Thracian treasures, which had been on exhibition at the Louvre museum since April, returned to Bulgaria late on Wednesday.

The return of the treasure was carried out under strict security measures, with its arrival at the airport and transportation to the National Historical Museum (NIM) being heavily guarded, private bTV station reports.

The Panagyurishte golden treasure along with 1300 Thracian artifacts were transported in fireproof cases on board of a small airplane.

On their way to the airport in Paris, the treasures were caught in a traffic jam in the French capital.

The only artifact that did not return to Bulgaria was the bronze head of Thracian King Seuthes III, which went on an exhibition in Los Angeles.

The treasure was welcomed personally by the director of NIM Bozhidar Dimitrov and the artifacts will be immediately displayed in the halls of the museum.

More than four million people visited the exhibition in the Louvre, which was on display for three months.

Meanwhile, Ancient Egyptian artifacts from the Louvre are displayed in the exhibition “Meeting an Egyptian Priest” in the Sofia History Museum in the Bulgarian capital and can be seen until September.
