The square was originally known as Plaza del Comercio before being renamed in honor of Manuel Dorrego, a prominent Argentine statesman.
The plaza served as a central point for water distribution in the city during the early 19th century.
Archaeological excavations in the area have uncovered colonial-era artifacts, confirming the site's role as a vital hub for early city commerce.
It is the only public square in Buenos Aires where antique dealers are officially permitted to set up stalls as part of the Sunday market.
The surrounding San Telmo district survived the 1871 yellow fever epidemic, which caused wealthier residents to relocate to the north, leaving the neighborhood's original architecture intact.
Plaza Dorrego is the historical heart of the San Telmo neighborhood in Buenos Aires, functioning as the city's second-oldest public square. It is best known for the Feria de San Telmo, a massive weekly antiques market that occupies the square and surrounding streets every Sunday. The plaza is surrounded by 19th-century colonial-style buildings and numerous cafes with outdoor seating. It frequently serves as a venue for impromptu public tango performances. The site was designated as a National Historic Site in 1978. Its architecture and atmosphere serve to preserve the aesthetic of colonial-era Buenos Aires. The square is built on a site that historically served as a rest stop for wagon trains heading to the port. Local cafes bordering the square have operated continuously for decades, maintaining traditional interior decor.

Avoid buying 'antique' items without verifying their authenticity, as many stalls sell modern reproductions targeting tourists.
The antique market operates exclusively on Sundays; the square is quiet and primarily used by local café patrons on weekdays.
Casual, comfortable walking shoes are essential due to uneven cobblestone streets. Respect the street performers by keeping a respectful distance during tango dances.
