It took until 1964 before Treblinka became a national monument. Because little remains of the original extermination camp, an attempt was made to let the camp relive in granite. A symbolic railway was laid with sleepers of granite. The fences and the watchtowers are also depicted in granite.
A large column now stands on the spot where the gas chambers used to be. It rises up from the center of a symbolic burial site containing 17,000 stones with the names of villages, cities and countries engraved on them whose Jewish inhabitants have been murdered in Treblinka. The pits in which the corpses were cremated are depicted by a material that resembles solidified tar.
