The 2nd arrondissement (2^e arrondissement) is one of the 20 arrondissements of Paris, the capital city of France. Located on the right bank of the River Seine, the 2nd arrondissement, together with the adjacent 8th and 9th arrondissements, hosts an important business district, centred on the Paris Opéra, which houses the city's most dense concentration of business activities. The arrondissement contains the former Paris Bourse (stock exchange) and a large number of banking headquarters, as well as a textile district, known as the Sentier, and the Opéra-Comique concert hall.
