Gustavo Adolfo Wulff Mowle, German saltpeter and coal trader, as well as maritime transporter, migrated to Chile in 1881. In 1904, he bought from Dr. Teodoro Von Schoeders 1,260 square metres (13,600 sq ft) in front of Cerro Castillo (Castle Hill), in Viña del Mar.[1] He built the new house in 1906.[2] By 1917, Wulff hired architect Alberto Cruz Montt to make the house into a castle.[1] Eventually a new tower was added built upon some rocks on the northern side of the castle, and a bridge joined them together.[1]
