The most popular tourist sites are found in the historic city core, comprising Montserrat and San Telmo. The city was originally constructed around the Plaza de Mayo, the administrative center of the Colony. To the east of the Square is the Casa Rosada, the official seat of the executive branch of the government of Argentina. To the north, the Catedral Metropolitana which has stood in the same location since colonial times, and the Banco de la Nación Argentina building, a parcel of land originally owned by Juan de Garay. Other important colonial institutions were Cabildo, to the west, which was renovated during the construction of Avenida de Mayo and Julio A. Roca. To the south is the Congreso de la Nación (National Congress), which currently houses the Academia Nacional de la Historia (National Academy of History). Lastly, to the northwest, is City Hall.
Avenida de Mayo links the Casa Rosada with the Argentine National Congress. On this avenue there are several buildings of cultural, architectural and historical importance, such as Casa de la Cultura, the Palacio Barolo and Café Tortoni. Underneath the avenue, the first subte (metro) line (Línea) in South America, was opened in 1913. The avenue ends at Plaza de los Dos Congresos, which features a number of monuments and sculptures, including a signed copy of Auguste Rodin's "The Thinker".
The Manzana de las Luces area features the San Ignacio church, the Colegio Nacional Buenos Aires, and the old city council building (1894 to 1931). This area has hidden tunnels, which crossed the city during colonial times.
In the neighbourhood of San Telmo, Plaza Dorrego holds an antiques fair on Sundays, complete with tango shows. There are several religious shops formed by the church of Nuestra Señora de Bethlem, Parroquia de San Pedro Telmo and Museo Penitenciario "Antonio Ballve". To the south stands the Museo Histórico Nacional on Parque Lezama.
In the barrio of Recoleta are located a number of tourist sites including the Museo Nacional de Bellas Artes, the Biblioteca Nacional, the Centro Cultural Recoleta, the Faculty of Law of the Universidad de Buenos Aires, the Basílica Nuestra Señora de Pilar, the Palais de Glace, the Bar La Biela and the Cementerio de la Recoleta, where the remains of Eva Duarte de Perón can be found.
El Ateneo is one of the city's most well-known bookshops situated in Santa Fé Aveneue, Barrio Norte. Once a theatre and later a cinema, the building still retains the feeling of the grand theatre it once was, despite its recent renovation.
