Visitors to Historical Park can always tour the grounds and read the information signs attached to most buildings. The park is located in the Prospect Hill Settlement District that includes the former Freewill Baptist Church building, the Alice Weston Memorial Garden, and the Weston Antique Orchard. Images of both the buildings and information signs are shown below.

The New Berlin Historical Society was chartered in 1965, and is an affiliate of the Wisconsin Historical Society. Its first home was the Miller farmhouse on Cleveland Avenue. In 1970 the City of New Berlin purchased the 3.5 acre Sprengel property, now known as Historical Park, in the Prospect Hill Settlement District. The Society has since Restored the house to its early 1900's period, Recreated a Country Store in the Carriage Building, Moved and Restored a local Log House, and Rescued and Restored the1863 One Room School House. The Society also Rescued and Restored Theodora Winton Youmans' childhood home. Ms. Youmans was Wisconsin's nationally famous suffragist and is credited with leading the Wisconsin legislators to a speedy vote and become the first state to approve the United States 19th Amendment granting women the right to vote.

A  major project of the society has been the transformation of the former fire station at 19885 National Ave. to a museum/office complex. In 2020  the existing building was renovated and a major addition was completed. The west bay of the station houses displays featuring the former volunteer fire department, The remaining exhibit space is devoted to showing the life and times of New Berlin's past through exhibits that include a country store, police and military history and  agricultural history told through the extensive Cornfalfa Farms collection of artifacts and images. These exhibits, and others under consideration, are works in progress as this is written (November 2021). The museum also houses office space, a conference room/library and a gift shop.
