When crowds of pro-Trump demonstrators congregated in downtown D.C. this weekend, some of them flocked to Black Lives Matter Plaza, tearing down signs and artwork that hung from the fence surrounding the White House.

Now, a handful of local activist groups have planned two art-making events to replace some of the art taken down over the weekend. The “art builds” are scheduled for Monday and Tuesday evening from 7:00-9:00 p.m. at Black Lives Matter Plaza. Organizers suggest participants bring art supplies, tape, zip ties and poster board.

“We ask you to join us as we go to collect what we can that remains as well as replace the art that’s been taken down,” one group, Good Trouble Co-op, posted on Instagram.

Black Lives Matter Plaza first became an outdoor gallery for a wide array of protest art when the racial justice protests began early this summer. Posters and signs have been removed numerous times before, only to crop up again hours or days later. Various activist groups have worked to ensure the area remains full of handmade art over the past five months.
