Ko te whare rangatira i hokona i te tau 1604 e Henry Hastings, 5th Earl o Huntingdon, nana nei tana ake whare rangatira i Ashby-de-la-Zouch. I whakangaromia te whare o Melbourne, ka whakamahia hei puna mo nga taonga hanga. Ko nga toenga katoa o Melbourne Castle i tenei ra ko te waahanga o te pakitara tata ki te 15 m (50 ft) te roa me te 4 m (13 ft) teitei me etahi turanga; kaore he mea e mohiotia mo te whakatakotoranga o roto o te whare o mua. Ko nga ruinga kua whakarārangihia te reanga II me te waahi kua whakaritea hei tohu whakamaharatanga. Kaore he urunga a te iwi ki te whare rangatira.
