Eribolum, Eribolon (Ancient Greek: Ἐρίβωλον), Eribolus, Eribolos (Ἐρίβωλος), or Eriboia (Ἐριβοία) was a port town of ancient Bithynia, on the Sinus Astacenus near Nicomedia. It appears in the Tabula Peutingeriana under the name of Eribulo, south of the bay of Astacus, with the numeral XII, and north of Nicaea; the figure of a house in the Tabula indicates a town, perhaps with warm springs. It is Hyribolum in the Jerusalem Itinerary. Cassius Dio speaks of it as a naval station opposite to Nicomedia. After the Battle of Antioch (in 218), the Roman emperor Macrinus fled to Eribolum seeking passage westwards while avoiding the large port of Nicomedia whose governor was in favour of the emperor Heliogabalus.Its site is located near Yeniköy, in Asiatic Turkey.

It was built for Pertev Mehmed Paşa, an Ottoman vizier during the reigns of sultan Suleyman I and Selim II. The construction was finished in 1579.

The İzmit Clock Tower (Turkish: İzmit Saat Kulesi) in İzmit, Turkey is one of many clock towers that were built throughout the Ottoman Empire as a result of the decree which was sent to the provincial governors to commemorate the 25th anniversary of Sultan Abdülhamid II's ascension to the Ottoman throne. It was designed by architect Vedat Tek upon the order of Musa Kazım Bey, the governor of İzmit, and built in 1902. Other sources name the architect of the tower as Mihran Azaryan who was an Armenian-Ottoman of Izmit origin.The neoclassical clock tower, which stands just in front of the Hünkar Pavilion of Sultan Abdülaziz, has four floors with dimensions 3.65 m × 3.65 m (12.0 ft × 12.0 ft). The ground floor houses fountains, while the clock is on the top floor. All four facades of the middle floors are decorated with the seal of Sultan Abdülhamid II. The pointed cone on top is coated with lead. The clock tower has been an inseparable part of the history of İzmit throughout the 20th century, and has become the symbol of the city. In the former Balkan provinces of the Ottoman Empire, particularly in present-day Serbian, Bosnian and Montenegrin towns such as Belgrade, Prijepolje, Sarajevo, Banja Luka, Gradačac and Stara Varoš, similar Ottoman era clock towers are still named Sahat Kula (deriving from the Turkish words Saat Kulesi, meaning Clock Tower.) It was restored in 2006.

Nicomedia (; Greek: Νικομήδεια, Nikomedeia; modern İzmit) was an ancient Greek city located in what is now Turkey. In 286, Nicomedia became the eastern and most senior capital city of the Roman Empire (chosen by the emperor Diocletian who ruled in the east), a status which the city maintained during the Tetrarchy system (293–324). The Tetrarchy ended with the Battle of Chrysopolis (Üsküdar) in 324, when Constantine defeated Licinius and became the sole emperor. In 330 Constantine chose for himself the nearby Byzantium (which was renamed Constantinople, modern Istanbul) as the new capital of the Roman Empire. The city was incorporated into the Ottoman Empire with the victory of Sultan Orhan Gazi against the Byzantine Empire. The Byzantines managed to retake it in the aftermath of the Battle of Ankara, but it fell definitively to the Ottomans in 1419.
