[14] Browne Hayes reputedly spent significant sums on the interior of the house, including murals and other artworks by artist Nathaniel Grogan (1740–1807).

[15] Following the death of his own wife, Henry Browne Hayes abducted a local heiress named Mary Pike, and in 1797 reputedly forced her into a marriage ceremony at the estate.

[17] Passing through several owners,[12] by the late 20th century the Vernon Mount estate was owned for a period by the Cork and Munster Motorcycle and Car Club.

[8][2] The Irish Georgian Society, World Monuments Fund, An Taisce and other stakeholder groups listed the building as a risk,[23][24] and attempts were made to slow the effects of deterioration, roof damage, water issues and vandalism over a number of decades.

[6][25] Although in private ownership, public funds were allocated by the Department of Arts and Heritage which allowed Cork County Council to undertake roof repairs in 2012.

[26] Despite recommendations for a compulsory purchase order, to bring the building into permanent state ownership and protection,[25] a severe fire in July 2016 reduced the structure to a largely empty shell.
