Sandwich History

The community of Sandwich was formed in 1834. The Chicago, Burlington & Quincy Railroad surveyed the area in the early 1850s. At that time, the property belonged to Almon Cage. The city was originally known as Almon in his honor, and he donated land for the construction of a depot. Cage donated free lots to people interested in starting a new life in the area. Congressman John Wentworth renamed the town Sandwich after his hometown of Sandwich, New Hampshire. Development of the town was expedited after 1855, and by 1860 there were more than 200 families residing in Sandwich.
