The less seen northern edge of Roosevelt Island

Most of the standard foot traffic on Roosevelt Island naturally flows south toward the manicured lawns of Four Freedoms Park. It’s a stunning, geometric tribute, to be sure. But on the opposite side, the island rewards you with a completely different kind of energy.

At the northernmost peak sits Lighthouse Park. It is a quiet, windswept three-acre green space where the city’s frantic pace feels strangely distant. Here, the East River fractures into the Hell Gate channel, framing a landscape that holds a massive, striking public art installation, a 19th-century stone lighthouse, and a heavy dose of New York history.

Stepping into the center of the park, you are immediately confronted by a series of monumental, seven-foot-tall metal faces. This is The Girl Puzzle, a powerful permanent installation by sculptor Amanda Matthews dedicated to the legendary investigative journalist Nellie Bly.

Just south of the park stands The Octagon, the remaining entry rotunda of the notorious Blackwell’s Island Insane Asylum. In 1887, a 23-year-old Bly famously feaked insanity to go undercover inside its walls, exposing the horrific, inhumane treatment of marginalized women in her landmark exposé Ten Days in a Mad-House.

Just beyond the gaze of the statues, at the very edge of the stone peninsula, stands the Blackwell Island Light. Built in 1872, this 50-foot gothic revival lighthouse is crafted from gray stone and looks like something pulled from a rugged New England coastline rather than a narrow strip of land sandwiched between Manhattan and Queens.

Legend long held that an asylum patient built the tower to prevent British ships from landing, but it was actually constructed by the city using patient labor. Decommissioned in the 1970s, it now stands as a beautifully weathered landmark, a silent sentinel watching over the turbulent waters where the East River meets the Harlem River.

Lighthouse Park doesn't feel like a typical New York City park. There are no bustling food trucks or crowded paths. Instead, the juxtaposition of the historic stone tower and the modern, fractured bronze faces creates a space that feels deeply reflective. It’s a reminder that New York’s history isn't just written in soaring skyscrapers, but in the places where brave people shone a light into the city's darkest corners.
