Kocaeli and its twelve districts
Kocaeli is a province in the east of the Marmara region, with its centre in İzmit. The Kocaeli Provincial Directorate of Culture and Tourism (Kocaeli İl Kültür ve Turizm Müdürlüğü) places it between the Black Sea in the north, Sakarya in the east and south-east, Bursa in the south, and Yalova and İstanbul in the west.
Mountains cover 18.8 % of the province: the Kocaeli Plateau (Kocaeli Platosu) in the north and the Samanlı mountains (Samanlı Dağları) in the south. The only significant lake is Sapanca, mostly in Sakarya. The directorate describes the climate as a meeting of Black Sea and Mediterranean types, with hot, dry summers, rainy and mild winters, and a cooler north coast.
Kocaeli Provincial Directorate of Culture and Tourism · checked 31.10.2026 · «Coğrafya»
The municipality’s heritage page explains the name: Akçakoca Bey, an Ottoman frontier commander who lived from 1234 to 1328, took the area, and it was called «Koca-ili», the land of Akçakoca Bey.
The directorate’s «Genel Bilgiler» page prints the area twice: 3,505 km² in its fact list (written «3.505», with the Turkish thousands point) and 3,623 km² in its text. It counts 13 municipalities, one metropolitan municipality (büyükşehir belediyesi) and twelve district municipalities. Kocaeli became a province (vilayet) in 1924.
İzmit
The provincial centre. The directorate says people have lived in and around İzmit since about 3000 BC. Nikomedya (Nicomedia), the capital of Bithynia (Bitinya, the ancient region), was founded by Nikomedes opposite Astakos.
Gebze
The directorate dates the known history of Bithynia, of which Gebze was part, back to the 12th century BC. Its Gebze page names the Çoban Mustafa Paşa Külliyesi (a mosque complex) and the Osman Hamdi Bey Müze-Evi (a house museum) among the district’s historic works.
Körfez
Körfez means gulf. Hereke lies in this district: a carpet and silk factory founded in 1843 and, beside it, a wooden kiosk that is open as a museum.
Kartepe
Kar is snow and tepe is hill. The district was formed in 2008, when the municipality of Köseköy took in nine smaller municipalities and was renamed Kartepe. Maşukiye and the cable car are in it.
Başiskele
Baş means head or first and iskele means pier: the directorate says the name belongs to the place of the first pier on the Gulf. The district was formed in 2008 by joining five town municipalities: Bahçecik, Yeniköy, Karşıyaka, Yuvacık and Kullar.
Çayırova
Çayır is meadow and ova is plain. The directorate says the name belongs to a wide meadow at the north-west of the Gulf, where the army of Sultan Mehmed II halted for a campaign in 1481.
Darıca
The name comes from Darıca Castle, 200 m north of the shore, of which one tower still stands. The directorate gives its earliest known name as «Tararion» and says a Byzantine list of roads names Darıca «Kalos Agros».
Derince
Derin is deep. The directorate says that in 1890 a place with the deepest shore on the Gulf was sought for a port, the site of today’s port was chosen and the place was called «Derince Liman». The district took its name from the port, whose building Germans began.
Dilovası
Diliskelesi, on the Gulf’s north shore, is the ancient Libyssa. The directorate lists five other ancient places there: Dakibyza (Gebze), Ritzion (Darıca), Niketiaton (Eskihisar), Charax (Hereke) and Philokrene (Bayramoğlu).
Gölcük
Göl is lake. The directorate dates the start of Gölcük as a garrison town to 1927: the 1925 decision to repair the battleship Yavuz created the need for a naval shipyard.
Kandıra
The district on the Black Sea. The directorate names the coastal towns Kefken, Kerpe, Bağırganlı, Kumcağız, Cebeci, Seyrek, Sarısu and Pınarlı, busy with visitors in summer, from İzmit, İstanbul and Adapazarı too, and more crowded at weekends.
Karamürsel
The directorate calls Karamürsel «Uygarlıkların Bahçesi», the Garden of Civilizations. A passenger ferry links it with İzmit and a passenger motorboat with Hereke.
İzmit: three museums and the old station
İzmit is the provincial centre. The directorate lists three museums attached to it, and the Turkish Museums portal (turkishmuseums.com) prints their hours and fees; the directorate’s museum links lead to that portal.
Closed on Mondays
For each of the three museums the portal prints «Pazartesi: Kapalı» (Monday: closed) and 09:00–17:30 on every other day, Saturday (Cumartesi) and Sunday (Pazar) included. The ticket office (gişe) closes at 17:00: «Gişe Kapanış 17:00». The portal prints the same hours for its summer (Yaz) and winter (Kış) seasons.

Days, hours and fees are as the pages printed them on 31.10.2026 and change by season and by year. The Turkish Museums portal is the site that the directorate’s museum links lead to; it prints the same hours for its summer and winter seasons.
Ormanya, the Osman Hamdi Bey Müze-Evi, the Çoban Mustafa Paşa Külliyesi and the museum ships print no days in these sources, and the Hereke kiosk prints no weekdays. The directorate’s page gives the area as 3,505 km² (written «3.505» there) and as 3,623 km². Train stations are quoted from the directorate’s «Nasıl Gidilir?» page; the railway company’s own station list is not used. The cover photo of the clock tower dates from 2016. Every photo is from Wikimedia Commons; its caption gives the author, date, licence and file page.
