Groups began gathering early Saturday morning, and police were in position at Emancipation Park and downtown Charlottesville at 6 a.m.
The park used to be named Lee Park, after the Confederate general, but Charlottesville City Council voted to change its name in June. "As long as that expression is peaceful, that is their right".
Right-wing blogger Jason Kessler, the organizer of the rally that is expected to draw "alt-right" activists and white nationalists, filed a lawsuit in federal court Thursday against the city of Charlottesville. President Donald Trump tweeted "There is no place for this kind of violence in America".
Several scuffles broke out at the rally after some of the nationalists swung their torches at people, the paper said, adding that several people were injured at the rally and at least one person was arrested.
But ACLU attorney Victor M. Glasberg said the Emancipation Park location is central to Kessler's rally because of the Lee statue and the controversy that has surrounded the city's decision to remove and rename the park.
The demonstration, which took place ahead of the alt-right Unite The Right event in the city's Emancipation Park on Saturday, led to violent exchanges with counter-protesters on the university grounds.
Organizers say the Unite the Right rally on Saturday aims to "unify the right-wing against a totalitarian Communist crackdown" and to protest "displacement level immigration policies" in the United States and Europe.
A Twitter user also shared a picture of the varsity students protesting against the white nationalists.
