Illés Relief is a 1:500 scale model of the city of Jerusalem, built for the Ottoman Pavilion at the 1873 Vienna World's Fair.
[1][2] It was based on the Ordnance Survey of Jerusalem and research by Conrad Schick.
It was hand-crafted between 1864 and 1873 by Stefan Illés (Hungarian: [ˈilleːʃ], Illés István), a Hungarian Catholic who lived in the city making a living from book binding.
The scale model reflects the city under the later stages of Ottoman rule.
[6] In 1985, then graduate student Moti Yair of the Hebrew University came across a reference to it and tried to track down its location.
