El Qasriga Hillsborough Waa guri ay daganyihiin saraakiisha dowlada Waqooyiga Ireland sida Xoghayaha Gobolka ee Waqooyiga Ireland, iyo guriga rasmiga ah ee Waqooyiga Ireland ee HM Queen Elizabeth II iyo xubnaha kale ee qoyska boqortooyada Ingiriiska markay booqdaan gobolka, iyo waliba guriga martida ee martida caalamiga ah ee caanka ah.
Laga soo bilaabo 1922 ilaa 1972 waxay ahayd hoyga Badhasaabka Waqooyiga Ireland. Jagada Guddoomiyaha, oo ahaa wakiilka waqooyiga Ireland, waxaa la baabi'iyay 1973.
Castill Hillsborough, oo ku taal magaalada Hillsborough, County Down, maahan qalcad run ah. Waa daar reer Georgia ah, oo loo dhisay qarnigii 18-aad qoyskii Hill, Marquesses of Downshire, oo iyadu lahayd ilaa 1922, markii Marquis-kii XNUMXaad uu daartii iyo garoonkeedii ka iibiyay dawladda Ingiriiska.
Iibsashadii dowladdu waxay ku xallisay dhibaato la taaban karo. Marka loo eego Sharciga Dowlada Ireland ee 1920 dowlad cusub oo la yiraahdo Northern Ireland ayaa la abuuray. Awoodda fulinta waxaa loo xilsaaray Waqooyiga Ayrland iyo Koonfurta Ireland ee Lord Lieutenant of Ireland, taas oo loo maleynayay inay ka mid tahay labada astaamood ee dhammaan Ireland (oo ay weheliso Golaha Ireland) ee qaab dhismeedka sharciga guriga cusub.
Si kastaba ha noqotee eedeyntaas waxaa laga saaray isbeddelka sharciga ka dib Heshiiskii Anglo-Irish ee 1921, kaas oo ka saaray Koonfurta Ireland (oo dhab ahaantii kaliya ku jirtay warqad) oo lagu beddelay Irish Free State. Xafiis cusub oo loo sameeyay Waqooyiga Ireland ayaa kaliya loo sameeyay in lagu buuxiyo booska, kaas oo ah Guddoomiyaha Waqooyiga Ireland.
Qalcadda Hillsborough, in kasta oo ay ka baxsan tahay caasimadda, Belfast, waxaa loo tixgeliyey inay tahay meel ku habboon. Dayactirka kadib, gudoomiyihii ugu horeeyey, James Albert Edward Hamilton, Duke-ka 3aad ee Abercorn, wuxuu guurey sanadkii 1925.
