The National Bank of Greece is founded in Athens.

The National Bank of Greece is a banking and financial services company with its headquarters in Athens, Greece. Founded in 1841 as the newly independent country's first financial institution, it has long been the largest Greek bank, a position it still held in the early 21st century. Following the financial turmoil of the Greek government-debt crisis in the 2010s, it remains one of Greece's four dominant banks together with Alpha Bank, Eurobank Ergasias, and Piraeus Bank. It has been designated as a Significant Institution since the entry into force of European Banking Supervision in 2014, and as a consequence is directly supervised by the European Central Bank. NBG offers financial products and services for corporate and institutional clients along with private and business customers. Services include banking services, brokerage, insurance, asset management, shipping finance, leasing and factoring markets.

Athens is the capital and largest city of Greece. A significant coastal urban area in the Mediterranean, Athens is also the capital of the Attica region and is the southernmost capital on the European mainland. With its urban area's population numbering over 3.6 million, it is the eighth-largest urban area in the European Union (EU). The Municipality of Athens, which constitutes a small administrative unit of the entire urban area, had a population of 643,452 (2021) within its official limits, and a land area of 38.96 km² (15.04 sq mi).
