[1] This detached three-storey country house was built 1754 and while the structure has been modified throughout its life, the castle still retains its architectural integrity.

[2] One of the former residents of Ballynahinch Castle was Richard Martin (Humanity Dick, 1754–1834), founder of the Society for the Prevention of Cruelty to Animals and Member of Parliament for County Galway.

[11] Richard Martin, known as "Humanity Dick" because of his commitment to animal welfare, converted the house to a private residence at some point, and lived for a considerable part of his life at the castle.

[14] Irish political leader Daniel O'Connell stayed at the castle as a guest of the Martin family in 1843, while he was attending a meeting nearby.

Ranjitsinhji provided considerable support to the Connemara region, investing in cottage industry and helping local business as well as employing more than fifty people on projects to improve the castle and estate.

[16] After Ranjitsinhji's death, his nephew sold the castle to the Dublin-based McCormack family, and in 1946 it passed into the control of the Irish Tourist Board who converted it into a hotel.
