The Rev. John Sergeant had the most benevolent, if paternalistic, of intentions: He sought to build a house among the members of the Housatonic tribe, hoping to convert them to "civilized" (that is, English) ways through proximity to his godly self and his small band of settlers. The weathered Mission House, built in 1739, was the site of this Christianizing process. History buffs, in particular, will enjoy the 45-minute guided tour.
