The Monte Cristo Cottage is the home of Eugene O'Neill, the only American playwright who won the Nobel Prize. Named after the character Edmund Dantes (or the Count of Monte Cristo), the popular role that his father James O'Neill often portrayed, the cottage is both a registered national landmark and a museum. It contains the personal belongings of the playwright including his portrait, as well as a display of the life and works of O'Neill. Visitors are given the chance to explore O'Neill's world and understand his oeuvre and philosophy.

The cottage was the playwright's summer abode in his childhood years. It is also the setting for two of his magnum opus, “Ah, Wilderness!” and “Long Day's Journey Into Night.” Its restoration began in 1972 and it was opened finally to the public in 2005. The general admission is $7 and $5 for students and seniors. Members can come and go without any entrance fee.
