direction by Pierre-Louis Gatier of the University of Lyon has been conducting archaeological and topographical work. When international archeological missions in Syria came to a halt after 2012 due to the war there, some of them instead started excavations in Tyre, amongst them a team headed by Leila Badre, director of the Archeological Museum of the American University of Beirut (AUB), and Belgian archaeologists. Threats to Tyre's ancient cultural heritage include development pressures and the illegal antiquities trade. A highway, planned for 2011, was expected to be built in areas that are deemed archaeologically sensitive. A small-scale geophysical survey indicated the presence of archaeological remains at proposed construction sites. The sites have not been investigated. Despite the relocation of a proposed traffic interchange, the lack of precise site boundaries confuses the issue of site preservation. A 2018 study of Mediterranean world heritage sites found that Tyre's City site has "the highest risk of coastal erosion under current climatic conditions, in addition to 'moderate' risk from extreme sea levels." Like many of the cities in the Levant and in Lebanon, the architecture since the Lebanese Civil War in the 1970s has been of poor quality, which tend to threaten the cultural heritage in the built environment before the war. Meanwhile, historical buildings from the Ottoman period like Khan Rabu and Khan Sour / Khan Ashkar have partly collapsed after decades of total neglect and lack of any maintenance whatsoever. In 2013, the International Association to Save Tyre (IAST) made headlines when it launched an online raffle in association with Sotheby's to fund the artisans' village Les Ateliers de Tyr at the outskirts of the city. Participants could purchase tickets for 100 euros to win the 1914 Man with Opera Hat painting by Pablo Picasso. The proceeds totaled US$5.26 million. The painting was won by a 25-year-old fire-safety official from Pennsylvania. IAST president Maha al-Khalil Chalabi is a daughter of feudal lord and politician Kazem el-Khalil. In September 2017, she opened "Les Atelier", which is located in the middle of an orangen grove covering an area of 7.300 m2 at the northeastern outskirts of Tyre. Biblical description The city of Tyre appears in many biblical traditions: Hebrew Bible / Old Testament According to Joshua 19, "the fortified city of Tyre" was allotted to the Tribe of Asher. King Hiram I of Tyre allied himself with David and Solomon in 2 Samuel, 1
