Overview
Union Square is a historic neighborhood in southwest Baltimore, Maryland, centered on Union Square Park — a handsome mid-19th-century residential square flanked by well-preserved Federal and Italianate rowhouses. The neighborhood sits roughly between Hollins Street to the north and Lombard Street to the south, and is part of the broader Pigtown/Washington Village area of the city.
The square's most famous association is with journalist and cultural critic H.L. Mencken, who lived on Hollins Street for much of his life. His home is considered a landmark of Baltimore literary history. The neighborhood also sits within easy walking or cycling distance of the B&O Railroad Museum, one of the finest railroad history collections in the United States.
Union Square is a living residential neighborhood rather than a tourist district. Visitors come primarily to see the park, the historic architecture, and nearby cultural attractions. It offers an authentic slice of Baltimore's rowhouse culture away from the Inner Harbor crowds.

Local Culture & Etiquette
Union Square reflects Baltimore's deeply rooted rowhouse culture — a city shaped by waves of working-class immigrant communities, industrial history, and civic neighborhood identity. The square itself is a product of 19th-century urban planning that prioritized small green commons within dense residential grids.
The neighborhood's association with H.L. Mencken gives it a literary and intellectual dimension within Baltimore's cultural history. Mencken's prolific writing about American life, politics, and culture makes Union Square a quiet point of pilgrimage for admirers of his work.
Baltimore's broader culture rewards curious, respectful visitors who engage with the city as a lived-in place rather than a curated attraction. Residents of Union Square are primarily long-term Baltimoreans; visitors should be mindful that this is an active residential community.
