Riverhead Mosaic Street Painting Festival Weekend

East End Arts & Humanities Council staged its 30th annual MOSAIC Festival in Riverhead on Sunday, May 31, turning streets and parking areas around Town Hall into a chalk-art site for the afternoon. The free event ran from noon to 5 p.m. at the Riverhead Town Hall Campus along West Second Street and Railroad Avenue, according to East End Arts and the Town of Riverhead. Organizers billed it as Long Island’s only chalk street art festival and said the event combined large pavement murals with music, food vendors and family activities. Local coverage published before and after the event described artists and visitors filling the site as Riverhead marked the festival’s 30th year. ### Where exactly did the festival take place this year? Riverhead Town Hall Campus was the 2026 site, not Main Street. East End Arts said MOSAIC30 was held between West Second Street and Railroad Avenue, and the Town of Riverhead calendar listed the location as the 4 West Second Street parking lot. RiverheadLOCAL reported after the festival that the event took place on West Second Street and in the parking lot behind Town Hall, off Railroad Avenue. (eastendarts.org) The outlet said the move was tied to ongoing downtown construction, which made a Main Street setup difficult and prevented use of the East End Arts grounds. ### What did visitors actually see on the pavement? (eastendarts.org) Artists created chalk mini-murals across the street, sidewalks and parking lot, according to East End Arts and RiverheadLOCAL. Organizers said the festival centered on community street painting, while local reports described colorful works spread across the site as visitors moved among vendors and activities. (riverheadlocal.com) The festival’s format drew on the Madonnari street-painting tradition, according to Riverhead News-Review and Northforker. Both outlets said artists and amateurs took part in the chalk art portion of the event, which has been running since 1996. ### How large was the event beyond the chalk art? (eastendarts.org) East End Arts listed artisan vendors, food and beer vendors, drum circles, dance, live music and family activities as part of the 2026 program. The organization’s event page also named judges for the chalk competition and published a main-stage schedule that included performances by Jude Roseto, Rally Girls, Retro Crew, Chloe Halpin and Daydream. (riverheadnewsreview.timesreview.com) RiverheadLOCAL said visitors browsed artisan offerings while children and adults joined a drum circle, face-painting and other entertainment. The publication’s account matched the broader program East End Arts posted before the event. ### Who organized it, and how was it described? East End Arts & Humanities Council presented the festival, according to its event materials and local coverage. (eastendarts.org) East End Arts called MOSAIC “The Most Colorful Day of the Year” and said the 2026 edition celebrated 30 years of the festival alongside the 250th anniversary of the United States. Northforker and Riverhead News-Review described the festival as one of the East End’s recurring spring events. (riverheadlocal.com) That characterization was theirs; the core verified facts are that the event was free, family-oriented and built around chalk street art in downtown Riverhead. (eastendarts.org) ### Was there a backup date or next step listed? June 7, 2026 was listed as the rain date on event postings published before the festival. East End LOCAL and RiverheadLOCAL both included that backup date in their notices for MOSAIC30. East End Arts kept festival details, vendor lists and program information on its MOSAIC event page, which remained the main source for lineup and participation information after the May 31 event.
