Giant Glass Plate Negatives of Sydney Harbour

Three giant glass plate negatives – measuring 1.35 x 0.94 meters (53” x 37”) – are understood to be the world’s largest 19th century wet-process negatives. These images record the view of Sydney Harbour in 1875, documenting the future site of the UNESCO world-heritage listed Sydney Opera House. Bernhardt Holterman was determined to promote his adopted home to the world through photography.

With Charles Bayliss they designed a 23-meter (87 foot) high purpose-built tower, turning the 3 meter-square (10 foot) room at the top into a giant camera. There, they created a series of colossal wet-process negatives capturing one of the world’s greatest harbours in photographs bigger than had been ever thought possible, and toured them around the globe.

Semmering Railway

The Semmering Railway is a topographically challenging section of what is known as the Sudbahn or southern railway line. It made it possible to travel in comfort by rail from Vienna and reach the eastern foothills of the Alps in Austria in only two hours.  It’s one of the world's first mountain railways.

Semmering 19UNESCO Memory of the World

The Documents on the Semmering Railway, from 1844-1910, detail the evolution of a major construction site and how the railway line’s, viaducts, and tunnels were built using engineering resources. They show technical innovations in the 19th century and the awareness that technical projects require meticulous documentation.
