These bottles were discovered as part of the rehabilitation and upgrading program of the Tangier medina, carried out by the Agency for the Promotion and Development of the North (APDN), under the supervision and monitoring of the wilaya of the Tangier-Tetouan-Al Hoceima region, said a press release from the Agency.

The same source explained that this collection of 15 large glass bottles was found carefully buried in the roof of one of the shops located on the wall surrounding Dar Debagh on the east side of the city, noting that these bottles were used in the preservation and transport of certain liquid substances, such as oil, juice and fermenters.

After being inspected by the regional heritage curator, it turned out that they belong to the type of bottles called Dames Jeanne, whose history is associated with an ancient tale dating back to the 14th century, APDN said, noting that these bottles have been kept as historical evidence for use in some of the city's museum exhibits.

The press release notes that some of these bottles bear the name of the city of Barcelona and others of the town of "Vilella", located near Tarragona (Spain), stressing that this type of bottle has continued to be manufactured and used until the middle of the 20th century.
