About Portland Exposition Building

Portland Exposition Building, also known as The Expo or Portland Expo, is a city-owned municipal arena located at 239 Park Avenue in Portland, Maine. Opened in 1915, it has operated continuously for more than a century and is cited as the oldest continually used multi-purpose arena in the United States. The venue seats approximately 3,000 guests, while its floor offers roughly 24,190 square feet of obstruction-free space that can be configured for sports, trade shows, expos, and other events.

The Expo’s event calendar reflects its flexible indoor setup. It hosts Maine Celtics games, minor-league professional basketball, high school and collegiate sports, volleyball, cheerleading and dance competitions, trade shows, expos, and community events. Its compact seating bowl surrounds the central event floor, creating a close-to-the-action atmosphere that feels different from modern large-scale arenas.

Portland Exposition Building is one of Portland’s most iconic and historic venues, known for its longevity, intimate arena scale, and role as the home of the Maine Celtics.

Location & Transportation

Portland Exposition Building is located at 239 Park Avenue, Portland, ME 04102 — near Hadlock Field and the surrounding Park Avenue sports complex.

Driving and Parking: Most visitors arrive by car. Parking is available on-street and in nearby lots in the Park Avenue area, but spaces around the sports complex can fill on busier event dates. Arriving early is the best way to give yourself time to park, walk to the arena, and enter without rushing.

Transit: Greater Portland METRO bus routes serve the area around Park Avenue. Transit is an option for getting to the Expo, though the venue is especially practical for guests driving from around Portland and nearby communities.

Rideshare: Uber and Lyft operate throughout Portland, and drop-off and pickup are straightforward along the Park Avenue frontage. After larger events, building in a little extra time for pickup can make the end of the night smoother.

Nearby Accommodation: Lodging is available throughout Portland, with the greatest concentration in and around downtown and the Old Port. Those areas are a short drive from the Expo and offer convenient access to restaurants, nightlife, and other city attractions.

Venue Navigation

Portland Exposition Building has a compact indoor layout built around a single-level seating bowl and central event floor. Understanding that simple setup in advance helps you move from the main entrance to your section quickly, especially on busier sports and competition dates.

Entrances and Access: The main entrance is on Park Avenue and leads guests into the arena concourse and seating bowl. From there, the compact footprint keeps the path to most sections direct.

Seating Levels: Seating is organized as a single-level bowl surrounding the floor. With approximately 3,000 seats, the arena keeps fans close to the action whether the floor is set for basketball, volleyball, competitions, or another event layout.

Getting to Your Section: The single-bowl design makes sections easy to locate from the main concourse. Standard stair access leads into the seating bowl, and staff and signage help guide guests to their rows.

How Much Do Tickets to Portland Exposition Building Cost?

Portland Exposition Building ticket prices vary significantly depending on the type of event, the team or participating groups, seating section, and demand — which is what you'd expect from a venue that hosts everything from community events and expos to Maine Celtics games.

For minor-league basketball, including Maine Celtics games, tickets are approximately $15–$50, with premium or courtside seating priced higher. Seat proximity to the floor, opponent, and overall demand can all influence where prices land for a specific game.

For tournaments, expos, and community events, pricing is typically lower, often starting around $10–$25. These events can be a strong value for guests who want access to the Expo’s flexible event floor and compact indoor setting.

Buying earlier generally provides better seat selection and pricing for higher-demand dates. As inventory shrinks and the event date gets closer, the best remaining sections can become more expensive, especially for popular games and busier competition dates.

Portland Exposition Building Seating Guide

Portland Exposition Building offers an intimate single-level seating bowl wrapped around the central event floor. Because the venue holds approximately 3,000 seats, even value sections keep fans connected to the atmosphere, while lower rows put guests especially close to the floor.

Best Seats at Portland Exposition Building

• Best value: Upper rows and corner or end sections typically offer the most affordable seating while still keeping the floor within clear view in the compact arena.
• Closest to the action: Lower rows nearest the floor place fans directly on the action, an especially strong fit for Maine Celtics games and court-based events.
• Best overall experience: Center-court or midline sections provide the best balance of sightline, proximity, and atmosphere in the single-level bowl.
• For groups: For games, tournaments, and community events with higher demand, coordinating seats early makes it easier to keep everyone together in the same section or row area.

Getting Ready for Your Portland Exposition Building Event

Once your tickets are confirmed, a few practical preparations make your visit run significantly smoother — especially at a compact indoor arena where parking around the Park Avenue sports complex can fill on busier dates.

• Download your tickets before you leave. Save your tickets to your phone's wallet or screenshot them before departing so you're ready at the arena entrance without needing a signal.
• Charge your phone fully. Digital ticketing is standard, and your phone is your entry. A portable battery pack is worth having for a full evening.
• Arrive early. On busier event dates, parking in the Park Avenue sports complex area can fill, so give yourself extra time to park, walk to the entrance, and get through the arena.
• Wear the right footwear. Portland Exposition Building is a compact single-level indoor arena with standard stair access to bowl seating, so comfortable shoes make it easier to move between the concourse and your row.
• Dress for indoor conditions. The venue is indoors and climate-controlled regardless of outside conditions.
• Check the bag policy in advance. Reviewing the venue's guidelines before packing prevents delays at security.
