Tomb of Suleyman Shah located on terrain feature Syria
The Tomb of Suleyman Shah (Arabic: ضريح سليمان شاه; Turkish: Süleyman Şah Türbesi) is, according to Ottoman tradition, the grave (tomb, mausoleum) housing the relics of Suleyman Shah (c. 1178–1236), grandfather of Osman I (d. 1323/4), the founder of the Ottoman Empire. This legendary tomb has since 1236 had three locations, all in present-day Syria.
From 1236 until 1973, its first location was near castle Qal'at Ja'bar in present-day Raqqa Governorate, Syria.
Under the Treaty of Lausanne (1923), breaking up the Ottoman Empire into Turkey, Syria, and other states, the tomb site remains the property of Turkey.
In 1973, when the area around castle Qal'at Ja'bar was due to be flooded under Lake Assad, the tomb by agreement between Turkey and Syria was moved 85 km (53 mi) northward on the Euphrates River in Syria, 27 km (17 mi) from the Turkish border.
In early 2015, during the Syrian Civil War, Turkey unilaterally moved the tomb again to a new site in Syria, about 180 m (590 ft) from the Turkish border, 22 km (14 mi) west of Kobanî and just north of the Syrian village of Ashme, evacuating the approximately 40 Turkish soldiers guarding the tomb. The Turkish government has stated that the relocation is temporary, and that it does not constitute any change to the status of the tomb site.The tomb by agreement between Turkey and Syria then was moved to a new location at 36°38′22″N 38°12′27″E some 85 kilometres (53 mi) northward but also on the Euphrates riverside and also in Syria, 10 km (6.2 mi) northwest of the town of Sarrin, in Aleppo Governorate, and some 27 km (17 mi) from the Turkish border.
Until February 2015, Turkey maintained at this site a small military presence as an honor guard.Events during the Syrian Civil War
On 5 August 2012, during the Syrian Civil War, the Turkish prime minister Recep Tayyip Erdoğan stated that "The tomb of Suleyman Shah [in Syria] and the land surrounding it is our territory. We cannot ignore any unfavorable act against that monument, as it would be an attack on our territory, as well as an attack on NATO land... Everyone knows his duty, and will continue to do what is necessary".New location
Since then, the tomb has been located in Turkish-controlled territory 180 metres (590 ft) inside Syria,
just north of the Syrian village of Ashme
and less than 2 km (1.2 mi) southeast of the Turkish village of Esmesi (Esmeler or Esme or Eshme) in the southernmost Turkish Birecik District of Şanliurfa,
5 km (3.1 mi) east of the Euphrates, 10 km (6.2 mi) northeast of the Syrian town of Jarabulus 
and 22 km (14 mi) west of Kobanî.The Turkish Foreign Minister has stated that the relocation is only a temporary measure
and that it does not constitute any change to the status of the tomb.
The Syrian government said the raid was an act of "flagrant aggression" and that it would hold Ankara responsible for its repercussions.
