The next time you visit the New Hampshire State House it will be 200 years old. The current State House opened its doors on June 2, 1819. There will be commemorative events all week, including opening ceremonies and tours this Sunday afternoon. On Thursday, there is a joint session and picnic honoring all legislators, current and former. If you plan on attending Thursday and you are not a current representative, please consider parking at the Everett Arena and take a shuttle bus to the State House. Also, there are some very interesting original documents on display such as an 1789 copy of the bill of rights (with all 12 of the articles!).
