Hoboken is a city in Hudson County, New Jersey, sitting on the Hudson River directly across from Manhattan's West Side. Known as the Mile Square City for its compact footprint, it packs roughly 60,000 residents into about 1.25 square miles, making it one of the densest cities in the United States. The city rose as a 19th-century port, shipbuilding, and manufacturing center, and much of that era survives in the brownstones and brick row houses that line its streets. The city's waterfront was long dominated by piers, docks, and industry before a decades-long transformation opened the riverfront to parks and recreation. Today the Hudson River Waterfront Walkway threads through a string of parks from the terminal north to the Weehawken line, and the skyline across the river provides a constant backdrop to daily life. Transportation defines the city. Hoboken Terminal, a historic Beaux-Arts landmark at the southern edge of the city, brings together PATH rapid transit, eight NJ Transit commuter rail lines, the Hudson-Bergen Light Rail, NY Waterway ferries, and numerous bus routes. That abundance of transit options makes a Manhattan commute measured in minutes rather than hours and is one of the principal reasons people choose Hoboken. The city is home to Stevens Institute of Technology, a research university whose campus crowns Castle Point overlooking the river. Frank Sinatra was born in Hoboken, and the city honors its native son with Sinatra Park along the waterfront. The population skews young and professional, drawn by walkability, transit access, and a dense concentration of restaurants, bars, and shops, particularly along Washington Street. That blend of old-world streets, a rebuilt riverfront, and immediate proximity to New York gives Hoboken its distinctive, energetic character.
