He was born in Bergen as a son of customs officer Werner Hosewinckel Christie (1785–1872) and Hansine Langsted (1802–1864).
Christie was educated at Polytechnic School of Hannover from 1849 to 1852 and in Karlsruhe from 1852 to 1854,[1] where he was a student of Friedrich Eisenlohr.
He was commissioned by the Society for the Preservation of Ancient Norwegian Monuments, and through his work drawing remnants of medieval architecture, he became intimately familiar with such structures in Norway.
He led restoration and preservation of a number of important medieval structures, including Håkonshallen and St Mary's Church in Bergen.
Christie also chaired the Society for the Preservation of Ancient Norwegian Monuments branch in Trondhjem.
