Taken as a whole, Globočnik's camps at Bełżec, Sobibór, and Treblinka had almost identical design, including staff members transferring between locations. The camps were situated within wooded areas well away from population centres. All were constructed near branch lines that linked to the Ostbahn. Each camp had an unloading ramp at a fake railway station, as well as a reception area that contained undressing barracks, barber shops, and money depositories. Beyond the receiving zone, at each camp was a narrow, camouflaged path known as the "Road to Heaven" (called "Himmelfahrtsstraße" or "der Schlauch" by the SS), which led to the extermination zone consisting of gas chambers, and the burial pits, up to deep, later replaced by cremation pyres with rails laid across the pits on concrete blocks; refuelled continuously by the "Totenjuden". Both Treblinka and Bełżec were equipped with powerful crawler excavators from Polish construction sites in the vicinity, capable of most digging tasks without disrupting surfaces. At each camp, the "SS" guards and Ukrainian Trawnikis lived in a separate area from the Jewish work units. Wooden watchtowers and barbed-wire fences camouflaged with pine branches surrounded all camps.
