Start your celebratory spring Saturday early with the grand opening of Richmond’s premiere architectural gem, the Institute for Contemporary Art at VCU. Not only is there a site-wide exhibition, “Declaration,” but it’s a day-long block party featuring artists, makers, interactive activities, music including Chance Fischer and Photosynthesizers, and food trucks, held outdoors on the Markel Center grounds. The party is free. 10 a.m. to 4 p.m. ica.vcu.edu.
