The St. Nicholas National Shrine is located within the park, as well as Fritz Koenig's The Sphere, the iconic sculpture salvaged from the World Trade Center site.

[7] It contains 826 panels, upon which are attached "periwinkle, Japanese spurge, winter creeper, sedge and Baltic ivy",[8] A walkway from the pedestrian bridge curves along the park.

There are wood benches and a small amphitheater-like elevated space at the western end of the park, facing West Street.

[12] The Sphere, a large cast bronze sculpture by German artist Fritz Koenig, had stood in Austin J. Tobin Plaza between the World Trade Center towers in Manhattan.

Recovered from the rubble after the September 11 attacks in 2001, whole but visibly damaged, The Sphere was re-erected in Battery Park, near the Hope Garden.

[19] On September 6, 2017, the Sphere was unveiled in its permanent home in Liberty Park, overlooking the World Trade Center site.

[20][21] The America's Response Monument, a life-and-a-half scale bronze statue commemorating the actions of U.S. Special Operations Forces in the first few weeks of the War in Afghanistan, was unveiled to the public during the Veteran's Day Parade in New York City on November 11, 2011.

[23] The inscription at base of the sculpture bears its name, America's Response Monument, and the Latin subtitle De Oppresso Liber.

[28][29] The statue was temporarily located in the West Street Lobby inside One World Financial Center in New York City opposite Ground Zero.

[33] The Archdioceses says that they just wanted the church back, and a third of the building would be a memorial for 9/11, and a place where people of all faiths could pray and remember those who died in the attacks.
