Further refurbishment work was carried out in the 1880s by Sir Herbert, 7th Baronet, who inherited Bodelwyddan Castle from his heirless cousin.
[11] By 1920, the cost of maintaining the castle and estate had grown too burdensome, and the Williams-Wynn family leased Bodelwyddan to Lowther College, a girls' private school.
The historic house and grounds were opened to the public and managed by Bodelwyddan Castle Trust, an independent registered charity.
[14] Partnerships were formed with the National Portrait Gallery and the Royal Academy of Arts, so that the castle could be used to display objects from these collections.
[4] In August 2019, the trustees advised that in addition to the castle, "public access is no longer granted for the woodlands, parklands, play area and trench experience".
[5] In mid-2021, Bourne Leisure Hotels agreed to purchase the remaining part of the Castle from Denbighshire County Council which had bought the lease to the building.
The council would retain the woodland, the meadow, a car park and the agricultural lands as well as the small lodge on the edge of the property.
[23] The castle is set within a large area of parkland, and formal gardens, the most recent of which was originally designed by Thomas Hayton Mawson in 1910.
