Est. 1861 · U.S. Senatorial Estate · Episcopal Girls School · Wisconsin Heritage Site · Kenosha County Park
The Durkee Mansion was completed in 1861 for Charles Durkee, a Wisconsin pioneer who served one term as a U.S. Senator from 1855 to 1861 and was finishing his Senate service as the building went up. The mansion sits on the Lake Michigan shoreline in Kenosha and was, in its first phase, a private estate.
In 1865 the property was converted into a school. According to Wikipedia, Milwaukee Magazine, and Visit Kenosha materials, Kemper Hall operated as an Episcopal girls school under the Sisters of St. Mary from 1870 until early 1975, when the school accepted its last student. New wings, a chapel, and dormitories were added during the school's century of operation, expanding the original mansion into a larger campus complex.
When the school closed, a preservation coalition raised the funds needed to purchase the buildings and conveyed them to Kenosha County. The complex now operates as the Kemper Center, a 17.5-acre county park on Lake Michigan that includes a conference center, a historic chapel, the Durkee Mansion, and the Anderson Arts Center.
Sources
The folklore associated with Kemper Hall centers on the Sisters of St. Mary, the Episcopal religious order that staffed the girls school for over a century. Milwaukee Magazine's reporting on the campus describes a recurring legend, unverified in surviving school records, concerning a Sister who arrived in 1899. According to the story, the Sister's mental state declined rapidly during her first year of service. She is said to have thrown herself from the rocks at the Lake Michigan shoreline below the campus and was reported missing for several days before her body was recovered.
In the years since, visitors to Kemper Center have reported seeing figures in dark religious habits at the upper-floor windows of the school buildings. The phenomenon is most often described as a still, watching figure rather than a moving one. Reports cluster on the dormitory wing and the chapel.
The Durkee Mansion itself, the older 1861 portion of the complex, is reported less frequently in the paranormal coverage. Where it is mentioned, accounts describe footsteps on the original wood staircases when the mansion is closed. Kemper Center does not market itself as a haunted attraction; the lore surfaces in Milwaukee Magazine and regional travel coverage rather than at the venue itself.

Salem, MA
The Jonathan Corwin House at 310 Essex Street is the only surviving structure in Salem with direct ties to the 1692 Salem witch trials. Built circa 1675 and purchased by Corwin that same year, the house served as the site of pretrial examinations for several of the accused. The property has operated as a museum since 1948 under City of Salem ownership.
