About Mariga Guinness
Lived 1932 – 1989 (aged 56). Mariga Guinness was a German preservationist and architectural conservationist.
Mariga Guinness (born Hermione Maria-Gabrielle von Urach; 21 September 1932 – 8 May 1989) was an architectural conservationist and socialite, and co-founder of the Irish Georgian Society.
Life Early life and family Mariga Guinness was born Hermione Maria-Gabrielle von Urach in London on 21 September 1932. She was the only child of the marriage of Prince Albrecht von Urach, from Lichtenstein Castle, a member of the House of Urach, a morganatic branch of the royal House of Württemberg, and his first wife, Rosemary Blackadder (1901–1975) from Berwickshire in Scotland, a journalist and artist, who were married in Oslo in 1931. She was a princess from birth. For the first few months of her life she was very ill.
In 1934, her parents, both working as journalists, moved the family to Venice. They later moved again, to Japan. Her mother developed depression, and in 1937 tried to gain uninvited access to Emperor Hirohito's palace with her daughter. This resulted in her mother being arrested, sedated, and deported, which was the beginning of a decline in her mental health which culminated in a lobotomy in 1941 and spending the rest of her life in private mental institutions. Urach was returned to Europe, where she was brought up by her godmother, Hermione Ramsden, in Surrey and Norway, and educated by as many as seventeen governesses, with brief spells in boarding schools. Until the age of eighteen she was known as Gabrielle.
Life in Ireland The couple moved to Ireland in 1955 where they rented Carton House, County Kildare. They shared a love of Georgian architecture which resulted in them buying Leixlip Castle in 1958, and establishing the Irish Georgian Society on 21 February the same year. Through the society they campaigned for the restoration and protection of architectural sites such as Mountjoy Square, the gateway to the Dromana estate in County Waterford, the Tailors' Hall in Dublin, and Conolly's Folly in County Kildare. In 1967 they bought Castletown House, also in County Kildare, with a plan to restore it, and make it a base for the Irish Georgian Society. Through Patrick, Mariga became grandmother of the fashion model Jasmine Guinness.
Popular culture In 2020, a new film on Guinness's life and work, entitled Memory of Mariga, received its US premiere as part of the Elizabethtown Film Festival on Saturday 19 September, at the Crowne Pointe Theatre in Elizabethtown, Kentucky. In 2021, the same film received its Irish premiere at the Fastnet Film Festival.
