A Belgian couple returning from a holiday in Turkey was detained last week after customs officials found three stones in their suitcase.

A report by local experts now shows that the stones do have a historical or archaeological value, though the couple said they had no idea.

The couple found three stones during a day trip in Manavgat, a town east of Antalya. The stones were put in their suitcase to bring back to Belgium, about a week ago – but this is against the rules in Turkey.

They were stopped at the airport and Kim was detained. Now, more than a week after the incident, the Belgian national is still not allowed to leave the country.

The stones they took were analysed by Antalya Museum and they concluded that 2 out of 3 stones she tried taking back to Belgium were archaeological artefacts.

In the meantime, the Provincial Directorate of Culture and Tourism of Antalya has had the three stones examined by experts from the Antalya Museum. “The stone with two stylised rosettes on it was an architectural decoration piece” and “the two marble pieces were floor covering pieces,” the experts concluded, meaning it was indeed forbidden, “due to their nature,” to take them out of the country.

It now remains to be seen which sanction the Belgian woman risks. She previously explained that they often take stones from holiday destinations as a souvenir: “We often take them as decoration for my aquarium.”
