This little log cabin was built for the Glessner's daughter, Fanny, in 1886. She would have been 8 years old at the time. As a little girl, she would have spent lots of time in her playhouse, baking, jarring jams, and having tea parties. When Fanny grew up and moved to The Cottage, she had the Playhouse brought down from its original location next to the Big House. Neither The Cottage nor the Big House remains standing today.

Fanny was short for Frances. She would eventually grow up to become America's first forensic scientist, made famous for her miniature recreations of homicide crime scenes called, "The Nutshell Studies of Unexplained Death." These tiny recreations were exact dioramas of real crime scenes, down to the exact detail, including work doors and windows. Frances' work earned her a position teaching semi-annual seminars at Harvard University in Boston, and was also made a captain of the New Hampshire State Police in 1943.
