Sait Halim Pasha Palace
The Open Problems Conference will be held in Sait Halim Pasha Palace, one of the most beautiful seaside palaces in Istanbul, whose history goes back to at least 150 years and as far as Egypt!

Sait Halim Pasha was the son of Mehmet Aldülhalim Pasha who was one of the four sons of Mehmet Ali Pasha of Kavala (Kavala is the second largest city in Northern Greece). Mehmet Ali Pasha (Muhammad Ali of Egypt) was an Ottoman commander of Albanian origin, and is regarded as the founder of modern Egypt because of the dramatic reforms in the military, economic and cultural spheres that he instituted. Sait Halim Pasha was born in Cairo in the year of 1863, and completed his education in private lessons in Cairo, and he learned Arabic, Persian, English and French. He studied politics for five years in Switzerland. The Palace had become the property of Prince Abdülhalim Pasha in the year of 1876, and was reconstructed to its current appearance by journeyman architect, Petraki Adamandidis of Dardanelles. The property was inherited by the nine children of the Abdülhalim Pasha, after his death in the year of 1890. After going through several owners, Sait Halim Pasha Palace was restored following a fire in 1995 under the name of “Prime Ministry Official Guest House”.

Istanbul
Founded on the Sarayburnu promontory around 660 BC as Byzantium, the city now known as Istanbul developed to become one of the most significant cities in history. For nearly sixteen centuries following its reestablishment as Constantinople in 330 AD, it served as the capital of four empires: the Roman Empire (330–395), the Byzantine Empire (395–1204 and 1261–1453), the Latin Empire (1204–1261), and the Ottoman Empire (1453–1922).[5] It was instrumental in the advancement of Christianity during Roman and Byzantine times, before the Ottomans conquered the city in 1453 and transformed it into an Islamic stronghold and the seat of the last caliphate.[6] Although the Republic of Turkey established its capital in Ankara, palaces and imperial mosques still line Istanbul's hills as visible reminders of the city's previous central role. Istanbul's strategic position along the historic Silk Road,[7] rail networks to Europe and the Middle East, and the only sea route between the Black Sea and the Mediterranean have helped foster an eclectic populace, although less so since the establishment of the Republic in 1923. Overlooked for the new capital during the interwar period, the city has since regained much of its prominence. The population of the city has increased tenfold since the 1950s, as migrants from across Anatolia have flocked to the metropolis and city limits have expanded to accommodate them.[8][9] Arts festivals were established at the end of the 20th century, while infrastructure improvements have produced a complex transportation network.

Dolmabahce Palace
The word "Dolmabahce" in English means "the filled garden", because the Dolmabahçe Palace is founded upon a reclaimed area by filling up the sea. It's a beautiful 19th century palace right by the Bosphorus, on the waterfront. It's in baroque and rococco style and very French. Many people think that it is a small model of the palace of Versailles in Paris, France.

When one enters the palace area, the first thing to see is the beautiful French style gardens. After having a lovely walk by the Bosphorus, one reaches the main building. The palace was constructed between1842-1853 by one of the Ottoman Sultans, Sultan Abdulmecid. The architect was a famous Armenian architect, Nikogos Balyan. The palace reflects the European and more "modern" side of the Ottoman Empire. The Sultans moved to Dolmabahçe Palace after its construction was finished and never went back to Topkapı Palace, which had hosted them for nearly four centuries.
