However, besides the protective canopy, the interior contains other modern items such as re-enforcing beams, metal ladders and measuring devices on the walls, all contributing to the slightly unnatural scene.
It was a "grand house", designed by the prominent Brisbane firm of Donoghue, Cusick and Edwards, but reflecting the influence of Kruschnitt's time spent in both Arizona and Mexico.
Kruttschnitt, with a background of developing mines in America for ASARCO's mining department, had taken on the challenge in 1930, of revitalising the ailing Mount Isa Mine at a time when the company was unable to meet outstanding financial commitments.
Casa Grande Ruins National Monument contains an imposing 4-storey building dating from the late Hohokam period, probably 14th century and contemporary with other well preserved ruins in Arizona such as the Tonto and Montezuma Castle monuments.
It is situated in the flat plain of central Arizona in between the Gila and Santa Cruz rivers, just north of Coolidge and about 15 miles from the larger town of Casa Grande.
