Per 
Object class: Euclid. (Building SCP)
Special containment procedures:
SCPxxxx is to be surveyed 24/7 by at least 20 Foundation personnel from a confirmed, safe distance of 1 kilometre and 17 motion sensitive cameras are to be placed in a circular shape around SCPXXXX in a radius of 15 meters. No unauthorised personnel may approach SCPxxxx at any time. Satellite images of SCPXXXX are to be blurred out. Testing has been discontinued.
Description:
SCPXXXX is a single room building in [REDACTED], Norway. SCPxxxx consists of a small brick building with a flat roof and only one known entrance: a dark pinewood door. SCPXXXX also contains a small window, wich does not reveal the interior of the building, because the window itself seems to absorb all light. Lastly, SCPXXXX consists of a chimney, located on the left side of the building. Anyone that enters within 700 meters of SCPXXXX will either be attracted or repelled by a smell that is created by chimney smoke coming from SCPXXXX. It is currently unknown why individuals do not get the same reaction. When a person who gets repelled by the smoke approaches SCPXXXX anyway, repulsion increases until toxicity. Any person that enters SCPXXXX, seems to vanish. No person is known to have ever left SCPXXXX. All radio contact is lost immediately. Any technical equipment endures distubances when close to SCPXXXX. Connections to SCP 3008 were assumed at first, but this idea has been discredited due to lack of evidence.
Addendum:1
Test with 5 D-class personnel
5 individuals who felt attracted to SCPXXXX were ordered to enter the building with a small sidearm and be ready to fire at any and all movement.
*D-XXXX opened front door
-" sh#t this is just as dark as that f#cking window."
~"Are you scared? Wow, I guess I'm going first then"
*All D-class personnel enter quickly after one another. All radio contact lost.
