That is where the counting will take place in the nation's first statewide election using ranked-choice voting.
The counting is expected to get underway Friday and last into next week.
Mainers voted for Shawn Moody as the Republican nominee for governor, but it was a much closer vote for the Democrats.
Attorney General Janet Mills and Adam Cote are separated by a few thousand votes and the counting could have an impact on the outcome of that race.
Maine residents also voted Tuesday to use ranked-choice voting in future elections.
