Mr. Gustavo Wulff, 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 where he had a house built and ready in 1908.
By 1917, Mr. Wulff hired architect Alberto Cruz Montt to make the house into a castle. Eventually a new tower was added built upon some rocks on the northern side of the castle, and a bridge joined them together.
The City bought the castle in 1959. From 1960 until 1988, it housed the Museo Naval de la Armada de Chile (Chilean Navy Forces Museum). Between 1990 and 1999, it lodged the collection of the writer Salvador Reyes Figueroa. In 1995, it was pronounced a National Historical Monument by Chilean Law.
