Dark Star Park Day 2022

Date and Time for this Past Event

  • Monday, Aug 1, 2022  9:15am - 9:45am

  Rosslyn Events


Don't miss the Rosslyn favorite tradition that only comes around once a year! Every Aug. 1 at precisely 9:32 a.m., shadows created by the poles at Dark Star Park align with shadow patterns on the ground.

This year, start your Monday morning with our livestream of the event on Facebook Live to watch the shadow alignment on Aug. 1, beginning at 9:15 a.m. We'll set up a camera at the park so you can watch comfortably from home. Cross your fingers for a sunny day and make sure to "like" our Facebook Page to get a notification when we go live!

If you'd like to watch in person, we'll have our team on-site with the #RosslynTrike during the event to give away free sunglasses and cake pops! This giveaway is limited to the first 50 attendees, so stop by while supplies last.


Unfortunately, the 2021 event was not livestreamed due to poor weather conditions. Get excited for August 1 with this video of Dark Star Park Day in 2020!


Arlington's first major commissioned art project, Dark Star Park, features large spheres designed to resemble fallen, extinguished stars. Each year on August 1, the day that William Henry Ross acquired the land that became Rosslyn in 1860, the actual shadows align with the shadow-images at 9:32 am. Learn more from Arlington Arts.


Dark Star Park is emblematic of Nancy Holt’s commitment to temporal and site-responsive sculpture. Located within a busy traffic intersection on a once-overlooked pocket of land, it features large, gunite spheres resembling fallen, extinguished stars alongside tunnels and vertical poles. Learn more about Nancy Holt and Dark Star Park with this recent article from Angela Anderson Adams for the Holt/Smithson Foundation.
