Galata is the former name of the Karaköy neighbourhood in Istanbul, which is located at the northern shore of the Golden Horn. The district is connected to the historic Fatih district by several bridges that cross the Golden Horn, most notably the Galata Bridge. The medieval citadel of Galata was a colony of the Republic of Genoa between 1273 and 1453. The famous Galata Tower was built by the Genoese in 1348 at the northernmost and highest point of the citadel. Galata is now a quarter within the district of Beyoğlu in Istanbul.

Karaköy is a station on the historic Tünel funicular railway in Beyoğlu, Istanbul. Located on Tersane Avenue, just north of the Golden Horn, it is the southern and lower terminus of the 573 m (1,880 ft) railway. The station is located at the ground floor of the IETT General Headquarters Building.

Bankalar Caddesi (English: Banks Street), alternatively known as Voyvoda Caddesi (English: Voivode Street), located in the historic Galata quarter (present-day Karaköy) within the district of Beyoğlu (Pera) in Istanbul, Turkey, was the financial centre of the Ottoman Empire. The street is mentioned with the name Voyvoda Yolu (English: Voivode Road) in the 17th century Seyahatnâme of Evliya Çelebi. It was the street where the prominent banks, financial institutions and insurance companies had their headquarters during the Ottoman era, including the Ottoman Central Bank (originally established as the Bank-ı Osmanî in 1856, and later reorganized as the Bank-ı Osmanî-i Şahane in 1863) and the Ottoman Stock Exchange (Dersaadet Tahvilat Borsası, established in 1866.) These buildings are still used as headquarters or branch offices by banks and other financial institutions. The southern stop of Tünel (1875), the world's second oldest subterranean railway line after London's Underground (1863), is located near the eastern entrance of Bankalar Caddesi. The Camondo Steps, a famous pedestrian stairway designed with a unique mix of the Neo-Baroque and early Art Nouveau styles, and built in circa 1870–1880 by the renowned Ottoman-Venetian Jewish banker Abraham Salomon Camondo, is also located on Bankalar Caddesi. The steps lead upstairs to the historic Rue Camondo (present-day Banker Sokak) and Kart Çınar Sokak (the westward extension of Banker Sokak) where the ruins of the Genoese Palazzo del Comune (1316), built by Montano de Marinis, the Podestà of Galata, is located a short walking distance to the left (west) of the stairway, behind the façade of the 1880s Bereket Han office building on Bankalar Caddesi.Bankalar Caddesi continued to be Istanbul's main financial district until the 1990s, when most Turkish banks began moving their headquarters to the modern central business districts of Levent and Maslak. In the final decades of the 20th century, the Istanbul Stock Exchange moved first to the 4th Vakıf Han building in Sirkeci, and in 1995 to its current building in the İstinye quarter of the Sarıyer district.
