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 ("Black Village" in Turkish), the modern name for ancient Galata, is a commercial quarter in the Beyoğlu district of Istanbul, Turkey, located at the northern part of the Golden Horn mouth on the European side of Bosphorus. Karaköy is one of the oldest and most historic districts of the city, and is today an important commercial center and transport hub. The location is connected with the surrounding neighborhoods through streets originating from Karaköy Square. The Galata Bridge links Karaköy to Eminönü in the southwest, Tersane Street to Azapkapı in the west, Voyvoda Street to Şişhane in the northwest, the steeply sloping Yüksek Kaldırım Street to Beyoğlu in the north, Kemeraltı Street and Necatibey Street to Tophane in the northeast. The commercial quarter, which was originally the meeting place for banks and insurance companies in the 19th century, is today also home to mechanical, electrical, plumbing and electronic parts suppliers.

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.
