Host Your Event At Downtown Portsmouth's Unique Waterfront Venue

Savor a new vantage point for experiencing Portsmouth's waterfront during meetings and social gatherings. Offering dramatic views of Portsmouth's Piscataqua River and bridges, The Envio is the newest, most unique event venue in the downtown area. This luxuriously designed third-floor venue is connected to the new AC Hotel Portsmouth Downtown Waterfront and can host up to 300 guests in a 4,390-square-foot ballroom that can be divided into three smaller spaces for more intimate events. Guests will be greeted by a pre-function area boasting floor-to-ceiling windows and a terrace offering sweeping views of the Portsmouth seaport and the Piscataqua River. Watch the bridges rise as the ships come and go while your guests marvel at the stylish space. Perched above The Envio you will find Rooftop at The Envio, Portsmouth’s newest restaurant and bar offering stunning waterfront views. At this casually sophisticated indoor/outdoor restaurant, guests enjoy signature cocktails, craft beers and eclectic seasonal cuisine crafted with locally sourced ingredients fresh from the farm and sea.
