Sauer Castle is an Italianate villa at 935 Shawnee Road in kansas-city-kansas, built in the early 1870s for German immigrant merchant Anton Sauer and designed by Asa Beebe Cross, the most prominent Kansas City architect of the period. Occupied by five generations of the Sauer family into the 1950s, the house then entered a long decline: decades of vacancy, vandalism, storm damage, and a protracted public dispute with absentee owner Carl Lopp, a Sauer descendant who held the property from 1988 until 2023 while accumulating code-violation fines and back taxes. Its silhouette on the bluff, and its emptiness, made it the metro’s best-known haunted-house legend. The house was listed on the National Register of Historic Places on August 2, 1977. It was acquired in 2023 by Mike Heitmann, who has been restoring it as an event venue; Wyandotte County approved rezoning in 2025 and authorized $11.5 million in industrial revenue bonds for the project on July 1, 2025.

Anton Sauer and the house (1869–1879)

Anton Sauer (1826–1879) was born in Germany — sources place his birth in Hessen, and describe stops in Australia and New York before he settled in the Kansas City area in 1867.1 He built businesses in the city including a grocery, a tannery, and a seed-importing firm.2 After marrying Maria (Mary) Einhellig Messerschmidt in 1868, he assembled a large tract on a bluff overlooking the Kansas River valley — sources give 63 or 75 acres — and commissioned a family house large enough for her two daughters from a previous marriage and the five children they had together.21

The architect was Asa Beebe Cross, whose work defined much of nineteenth-century Kansas City.32 The result is a brick Italianate villa with classical proportions, bracketed eaves, tall narrow windows, and a four-story tower — commonly cited at about 60 feet — that gave the house its castle nickname and a view across the valley.3 Interior finishes included imported marble fireplaces, walnut doors, and a plumbing system fed by water pumped from nearby springs, unusual for its date.2

Construction dates vary by source: the National Register-derived accounts give 1871–1873, while the Kansas City, Kansas Public Library dates the work 1869–1871.31 A frequently repeated local story holds that Sauer chose the site because it reminded him of his birthplace along the Rhine; the library presents this explicitly as legend.1

Sauer died in the house in 1879. His widow Marie remained there until 1919, and Sauer children and their families occupied the house into the 1950s.1

Decline (1950s–2023)

After the family moved out, the property passed through other hands and deteriorated. Wikipedia dates the sharp decline to after the death of owner Paul Berry in 1986.3 In 1988 Carl Lopp, a great-great-grandson of Anton Sauer, bought the house, and it stood essentially vacant under his ownership for the next 35 years.34

The condition documented by the Kansas City Star in 2021 was severe: the front porch had caved in, the four-story tower was at risk of collapse, and the city had boarded the windows. Wyandotte County had posted the house as unfit for habitation. Lopp owed roughly $17,000 in code-violation fines, $7,000 in back taxes and fees on the castle, and $14,000 in overdue taxes on nearby parcels; he disputed the county’s actions, calling the effort “a scam” aimed at taking his property.4 In a Star reader survey that year, 83 percent of respondents supported using eminent domain to take the house if that was what preservation required.4 The property was listed for sale at $10 million in 2022, a figure well above any credible market value.3

The ghost legend

Sauer Castle has been the subject of persistent local ghost stories for decades, and the Kansas City Star has described it as the city’s “designated haunted mansion.”5 Reporting consistently treats the legend as folklore attached to a large, conspicuous, long-empty house rather than as documented event, and ties it to the practical problem of trespassing: the stories drew intruders and ghost hunters onto the grounds, contributing to the vandalism that accelerated the building’s decay.26 No specific verified incident underlies the legend; accounts of its origin are.

National Register listing (1977)

Sauer Castle was entered on the Register of Historic Kansas Places on July 1, 1977, and added to the National Register of Historic Places on August 2, 1977 (NRHP reference number 77000600).3 It was also placed on the Kansas City, Kansas historic landmarks registry on January 29, 1987.3 A Kansas City, Kansas Public Library historian has called it “without a doubt, the most famous residence in Kansas City, Kansas.”13

Sale and restoration (2023–present)

In 2023 the property was acquired by Mike Heitmann, an engineer and historic-home renovator, through Sauer Castle, LLC.56 Accounts of the mechanism differ: the Kansas City Star reported a purchase from Carl Lopp, while KC Studio described the acquisition as coming through a Wyandotte County tax sale.56 The exact conveyance is.

Restoration began in late 2023 with architects from STRATA Architecture + Preservation, working to National Register standards. Early phases addressed structural stabilization, the brick facade, the four-story tower and its winding staircase, the roof and guttering, and the fireplaces.6 The Star has reported a restoration budget of roughly $8 million.5

The intended use is a private event and wedding venue rather than a daily-admission attraction, with reported plans for bar service, overnight lodging, and capacity for about 180 guests, and a longer-term ambition for a museum, coffee shop, and gift shop.5 Wyandotte County commissioners approved the necessary zoning change and special-use permits in June 2025, and on July 1, 2025 the Unified Government’s full commission authorized $11.5 million in industrial revenue bonds covering three parcels — 911, 935, and 945 Shawnee — for interior and exterior renovation plus event lawn and parking.7

Published timelines have slipped repeatedly: a 2024 account projected completion in fall 2025; mid-2025 reporting pointed to completion in 2026; the bond coverage indicated operations commencing in 2027.657 The current construction status and an opening date as of August 2026 are.

Significance to Kansas City

Sauer Castle is the best-preserved surviving domestic work of Asa Beebe Cross on the Kansas side of the state line and one of the metro’s clearest examples of high Italianate residential architecture. Its position on the bluff above the Kansas River valley, at the edge of the strawberry-hill area, made it a landmark visible far beyond its own block — which is much of why its neglect became a civic argument rather than a private one. The thirty-five-year standoff over the house is a compact case study in the limits of historic designation: National Register listing conferred prestige but no power to compel maintenance, and preservation ultimately depended on a change of ownership.
