Architecture and Decor

Rosemount House

The mansion, designed by noted Victorian architect Henry Hudson Holly of New York, was built at a cost of $60,750.00. The 24,000 sq. ft. home is constructed in the Richardsonian Romanesque style, of pink volcanic stone, quarried near Castle Rock, Colorado.

Pink Volcanic Stone

Rosemount features beautiful oak, cherry, maple and mahogany woodwork. The home's golden oak entrance hall exhibits a coffered ceiling and the largest of the home's Tiffany chandeliers. The dramatic oak staircase nearby directs you past an exquisite 9 x 13 foot stained glass window, "Kingdoms of Nature," designed by Charles Booth of New York. The Thatcher family dedicated the windows as a memorial to Lenore and Albert, their two children who did not live to see Rosemount completed.
