Early Settlements and Colonial Growth

Buenos Aires was first established on February 2, 1536, by a Spanish expedition led by Pedro de Mendoza, named Ciudad de Nuestra Señora Santa María del Buen Ayre. This initial settlement was abandoned by 1542 due to indigenous attacks and supply shortages. A second, permanent founding occurred in 1580 by Juan de Garay, who named it "de la Santísima Trinidad" at the port of Santa María.

During the colonial period, Buenos Aires was isolated from major trade routes. Spanish law restricted its ports from importing European goods and exporting precious metals from regions like Potosí and Lima. This led to a substantial illegal trade with English, Portuguese, and French merchants, which allowed the settlement to grow. In 1776, Spain designated Buenos Aires as the capital of the new Viceroyalty of the Río de la Plata. This status brought an influx of lawyers, bureaucrats, soldiers, and enslaved people, leading to a significant expansion and establishing the city as a regional center.

Independence and European Urban Development

The 19th century brought significant change. Following Napoleon's invasion of Spain, the Council of Buenos Aires declared independence on May 25, 1810, an event known as the May Revolution. Formal independence for the United Provinces of the Río de la Plata was declared in 1816. Buenos Aires became the capital of the unified Argentine nation in 1862.

The late 19th and early 20th centuries saw Buenos Aires undergo a period of growth. Between 1864 and 1914, the city's population increased eightfold due to European immigration, primarily from Italy and Spain, but also from France and Germany. From 1880 to 1910, urban development was influenced by the Parisian "Haussmann" style. Grand avenues, squares, and public buildings were constructed. This period gave the city much of its European architectural character, with styles including Neoclassical, Beaux-Arts, Art Nouveau, and Art Deco.

• —Plaza de Mayo — This square is the oldest public square in Buenos Aires. It has been central to many moments in Argentine history, including the May Revolution of 1810. The Casa Rosada, the Metropolitan Cathedral, and the Cabildo stand around it. The Mothers of the Plaza de Mayo gather here every Thursday.
• —Pirámide de Mayo — In the center of Plaza de Mayo, this is the oldest national monument in Buenos Aires. It was erected in 1811 to commemorate the first anniversary of the May Revolution. It was renovated in 1856 and moved 63 meters east in 1912.
• —Cabildo of Buenos Aires — This colonial town hall, facing Plaza de Mayo, is an example of Spanish colonial architecture. It played a role in the events leading to Argentina's independence in 1810 and now houses a historical museum.
• —Casa Rosada — The official seat of the national government, this pink building overlooks Plaza de Mayo. Its Renaissance-style facade was completed in 1884. Eva Perón addressed crowds from its balcony in the late 1940s.
• —Metropolitan Cathedral of Buenos Aires — On Plaza de Mayo, this neoclassical building was completed in 1822. Its facade is inspired by the Palais Bourbon in Paris. It houses the mausoleum of General José de San Martín, an Argentine independence hero.
• —Manzana de las Luces — This block contains some of the city's oldest colonial structures, including a former Jesuit mission. It offers a view of Buenos Aires's early history and architectural styles.
• —Caminito Street — In the La Boca neighborhood, Caminito is a pedestrian street museum. Originally a stream, then a railway track, it was transformed in the 1950s by local artist Benito Quinquela Martín, who painted the houses with leftover ship paint. It inspired the 1926 tango of the same name.
• —Nicolás Avellaneda Transporter Bridge — Opened in 1914, this iron structure in La Boca is a National Historic Monument. It connected La Boca with Isla Maciel, transporting people, vehicles, and trams across the Riachuelo River until 1960. It resumed operation in 2017 after restoration.

The best times to visit Buenos Aires are during spring (October–November) and fall (March–April). These seasons offer mild temperatures, typically between 18-25°C (64-77°F), suitable for walking and sightseeing. In spring, jacaranda trees bloom. Fall brings golden foliage to parks. Crowds are generally smaller and hotel prices more reasonable than in summer.

Avoid visiting during the summer months (December–February) if high heat and humidity are a concern. Temperatures can reach up to 30°C (86°F), and it is the rainiest season, though storms are usually brief. While many locals leave the city, international tourist numbers remain high, especially around Christmas and New Year's, leading to higher costs.

Buenos Aires is served by Ezeiza (Pistarini) International Airport (EZE) for international flights and Aeroparque (Jorge Newbery) (AEP) for domestic connections. The city center has a grid layout, but many streets are one-way. Using GPS or navigation apps is recommended if driving.

Walking is suitable for exploring many neighborhoods, especially central areas like San Telmo and Recoleta. For longer distances, the city has public transportation, including subways (Subte), buses (colectivos), and trains. Taxis and ride-sharing services like Uber and Cabify are available.

Parking can be challenging. Street parking is permitted on both sides of most streets from 9 PM to 7 AM, and on one side during the day, but it is limited in commercial areas. Commercial parking garages (cocheras or estacionamientos) are available, particularly in Microcentro, Recoleta, and Palermo. Look for large 'E' signs.
