Est. 1928 · Michigan Historic Site · Comptometer Heritage · Catholic Seminary · Public Restoration Project
Dorr Eugene Felt amassed a fortune in late-Victorian Chicago as the inventor and manufacturer of the Comptometer, a key-driven mechanical calculator that became standard equipment in American business. He purchased a tract of land near Saugatuck in the early 1920s as a summer estate for his family.
The main house was completed in 1928. It is a twelve-thousand-square-foot Renaissance Revival residence with a ballroom on the third floor, a carriage house, and a private chapel added later. Agnes Felt, Dorr's wife, moved into the completed house in the summer of 1928 and died of a stroke six weeks later. Dorr Felt died in 1930.
The property changed hands multiple times after the Felt family departed. From 1949 to 1977, it operated as St. Augustine Seminary, a Catholic boys' school run by the Diocese of Lansing. After the seminary closed, the property was used briefly as a convent, then transferred to the State of Michigan for use as a State Police post and as housing for staff at a nearby state correctional facility.
In 1996, Laketown Township purchased the deteriorated estate. Restoration has been led by the volunteer-driven Felt Estate organization, with public tours funding the ongoing preservation work. The grounds, ballroom, and most main-floor rooms have been returned to their 1928 appearance. Restoration of the upper floors is ongoing.
The Felt Estate is recognized on the State of Michigan's register of historic sites and operates as a nonprofit cultural and event venue.
Sources
Agnes Felt occupied the mansion she had helped design for less than two months. She died of a stroke in 1928 in an upstairs bedroom that has since been restored to her period. Visiting guides routinely identify her as the figure most often associated with reported phenomena.
The third-floor ballroom draws the most consistent reports. Investigators with the West Michigan Ghost Hunters Society have published findings of audio anomalies and photographic orbs centered on the ballroom and an adjoining hallway. Visitors on candlelit Hauntings & History tours describe doors that open and close on their own, particularly between the library and the ballroom.
Guides on the regular daytime tour mention shadow movement in the library, where a photograph of Agnes hangs near the doorway. The library and Agnes's bedroom are the two rooms cited most often in published guest accounts and in the Hotel Saugatuck blog's interview-based reporting.
The mansion's institutional eras add additional layers to the lore. Reports from the seminary period describe footsteps in empty corridors. Anecdotes from the State Police era are circulated by docents but lack archival documentation. The estate's nonprofit operators present these stories as part of the building's cultural history rather than as confirmed claims.
Notable Entities
Walk Dorr Felt's 1928 summer estate, including the ballroom that local investigators identify as the most active room in the building. Self-guided tours run roughly an hour; private guided tours for groups of eight or more last about ninety minutes and cover spaces normally restricted to the public.
An annual October event, typically across three nights, that opens the mansion after dark for candlelit, self-guided exploration. Visitors begin with a presentation on the Felt family and the building's institutional history before exploring the grounds, carriage house, and main house using only candles. Guests may bring personal investigation equipment.
Every HauntBound history is researched from documented sources. We clearly separate verified historical fact from paranormal folklore.

The Quincy Mining Company began extracting copper from the Keweenaw Peninsula in 1846 and operated continuously until 1945, producing nearly a billion pounds of copper. During that period, 253 workers died in documented underground accidents. At its deepest, the mine reached 9,000 feet — the deepest copper mine in the world at the time — and its No. 2 shaft hoist house is a National Historic Landmark.

USS LST-393 is one of only two surviving LSTs from World War II still accessible to the public. Built in 1942 and commissioned in 1943, she participated in the invasion of Sicily, the Normandy landings on D-Day, and operations in the Pacific before being decommissioned and eventually converted to a Great Lakes ferry. Saved from scrapping in 2000, she has been a museum ship on Muskegon Lake since 2005.
Marquette, MI
Marquette Harbor Lighthouse was constructed in 1866 on Lake Superior to guide ore and freight traffic through one of the Upper Peninsula's primary shipping ports. The station operated continuously under a succession of keepers; assistant keeper Adam B. Sayles, whose service records from 1937 to 1940 are preserved in historical archives, died of a heart attack inside the building in 1942. The Marquette Maritime Museum took over operation of the lighthouse and runs daily guided tours.
