Located on the corner of Church and Main Street in Layton, this property has stood as one of Layton's most beloved landmarks. It was built in 1890 (6 years before Utah became a state) by Rufus Adams and his wife Sarah Hill and remained in a family blood will until it was purchased in 1995 by Debra Darrington.
At the time of Rufus' death, his daughter Alta inherited the home and continued to live in the home until her death March 22, 1986. Alta married Wallace William Cowley in May 1910 thus informally identifying the property as the Adams-Cowley Mansion. Hal Cowley inherited the home at the death of his mother but the home was greatly in need of modernization and so the property moved on and off the market for a decade until it was purchased by Debra in December of 1995. Finding innovative ways to work around the century old construction, the building was completely renovated to include central air, new plumbing and electrical, and an automatic irrigation system replaced the flood irrigation. It was opened to the public as a wedding venue called The Chantilly Mansion in May 1996. The North Solarium was added in 1998 and the South Conservatory and East commercial kitchen was added in 2008.
Fast-forward to 2020, The Chantilly Mansion was closed due to Covid and remained vacant until 2023, when Debra saw fit to close one chapter and focus on other things. In early December of 2023, the property was sold to a couple of people passionate about preserving history and hosting events. It is currently undergoing a cosmetic update and will host its grand reopening in early 2024 as The Caledonia at the Old Chantilly.
