The Old State House was built in the early 1700s and is the oldest public building in Boston. It was originally used for the royal government in the New World and was the location of many historical events. It was the location of The Boston Massacre, as well as the first reading to the public of the Declaration of Independence in the entire state. It is open daily year-round from 9 am until 5 pm, although this changes to 4 pm throughout January. There is a small admission charge, except Boston children and the elderly can get in for free. However, they offer self-guided tours that are free, as well as guided towards (which may cost a small fee).
