Union Square Park opened to the public in 1839, but it wasn’t until it was redesigned some 30 years later, by Frederick Law Olmsted and Calvert Vaux, that it became a public forum and a gathering place in the name of social justice. Last Friday, a crowd gathered again in the park, this time to welcome a trio of sculptures.
