The Auschwitz-Birkenau State Museum was created by an act of the Polish parliament on July 2, 1947, and includes the grounds of two extant parts of the Auschwitz I and Auschwitz II-Birkenau concentration camps. The Museum grounds cover 191 hectares, of which 20 are at Auschwitz I and 171 at Auschwitz II-Birkenau. On the museum grounds stand several hundred camp buildings and ruins, including the ruins of the gas chambers and crematoria, over a dozen kilometers of camp fence, camp roads, and the railroad spur ("ramp") at Birkenau.
