More than 600 people gathered for Sunday's ceremonies.
The founder of the Black AIDS Institute, Phill Wilson, said those who succumbed to the disease should not have died in vain.
"We owe it to every name that's in that circle, for every person who is named or not named who has been lost to this disease, we owe it to them to bring about the end of this epidemic," he said.
Wilson was referring to the grove's Circle of Friends.
The ceremonies concluded with supporters gathering for the reading of the names of those engraved into the circle.
