Item#: SCP173 (aka "The Golem")
Special Containment Procedures: Item SPC173 is to be kept in a locked container at all times. When personnel must enter SCP173's container, no fewer than three (3) may enter at any time and the door is to be locked behind them. At all times, two persons must be looking at SCP173 until all personnel have vacated and relocked the container.
Description: Moved to Site 19 in 1993, little is known about item number SPC173's origins. It is constructed from concrete and rebar and was once painted with Krylon brand spray paint.
SCP173, more commonly known as "The Golem", is animate and malevolent, if given the chance it will kill anyone within it's line of sight. However, its weakness is that it does not move while being watched. Despite this paralysis it is still highly dangerous; able to cover at least two (2) meters in the literal blink of an eye. It typically kills by either snapping the victim's neck from behind, or grabbing the victim's throat and strangling them. Whatever animates SCP173 does not give it much force with which to break things, as seen above a large room with unbarred windows is fully capable of containing it. Its grip however is unbreakable, as when it is not moving the statue is as hard and strong as concrete.
While left alone in it's room, one can hear a stone-on-stone scraping from within that is believed to be the sound of the SCP173 moving about.
The reddish brown substance on the floor is a combination of feces and blood. All DNA testing has proved inconclusive thus far. We do not know (nor wish to find out) where it comes from or how it arrives, but SCP173's container will slowly fill with these substances. In order to ensure that bacterial growth within does not begin to damage the building it is contained within, and to maintain some level of sanitation, the enclosure must be cleaned on a bi-weekly basis.
