Created to mark the renovation and beautification of Downtown Portsmouth – and in particular Market Square – the Festival continues to grow in popularity and is often referred to as the unofficial start of Summer on the Seacoast, enticing an estimated 80,000 to enjoy this destination festival in Downtown Portsmouth. The event features regional artists, music and dance, the history of the City andthe members of the business community. The downtown area is transformed into a pedestrian-friendlyspace as streets are closed from 9:00am through 5:00pm.

The day begins with the Market Square Day 10K Road Race, which winds its way through the streets of Portsmouth.
