Item #: E-408, SCP-XXXX

Object Class: Extra-Dimensional

Containment Class: Varied

Special Containment Procedures: Effective containment of E-408 can be accomplished by containing SCP-XXXX. Respectively:

The property housing SCP-XXXX-1 has been purchased by the Foundation and converted into a covert research center for E-408 . Trespassers are to be turned away.

Due to failures to negotiate with the owners of the property containing SCP-XXXX-2 , it has been destroyed by covert agents and is considered potentially neutralized. It is to be monitored in order to detect potential future anomalous effects.

It is to be monitored in order to detect potential future anomalous effects. Covert agents have been embedded into the clergy at the San Sebastiano fuori le mura basilica in order to watch for users of SCP-XXXX-3 .

. The original entrance to SCP-XXXX-4 has been filled with concrete.

Monthly incursions into E-408 are to be conducted in order to monitor for the appearance of new phenomena. Evidence of any sufficiently advanced life within E-408 is considered an Alpha-Level Containment Threat and must be contained if possible.

Description: E-408 is the designation given to a large space measured to be at least 17 million kilometers squared in area. The atmosphere, gravity, and geographical features match those of the eastern Mediterranean. Several notable artificial landmarks exist within E-408; see exploration logs below.

There are several known methods of access to E-408, classified collectively as SCP-XXXX. As of the time of writing, there are five SCP-XXXX instances known to the Foundation.

SCP-XXXX-1 refers to a door found in the basement of an Istanbul household. It acts as a two-way portal to the ruins of a large city within E-408 .

Each instance of SCP-XXXX was discovered independently, and were eventually determined to lead to the same space. Personnel with appropriate clearance may see the exploration logs listed below for more information on discovery and access.

It has been noted that there are sentient animals such as birds and fish within E-408, as well as significant plant life. The ruins within E-408 imply that there was once sapient life within E-408; this has yet to be encountered by incursion teams.

Addendum XXXX-1: Associated Document

Note: Recovered from the Vatican archives, dating back to the 2nd century C.E. Originally written in Latin. Author unknown.

Our researchers have located a room buried beneath the dirt and grime of Byzantium. It was reinforced with stone and iron, and took quite an effort from our construction teams to excavate. We only knew about it due to the tales of one of the old Egyptian hermits that lived here; otherwise, it would have been lost to time. It appeared to house some kind of facility, all appearing to maintain some kind of doorway. When one of my associated stepped through, he saw an endless landscape of forest for as far as the eye can see. Perhaps it could be the work of some demon or god? We have yet to see anything of note, from the soldiers we've already sent in. If it truly is the realm of some extranormal creature, it is quite a plain one. If I may suggest, it could be converted into some kind of shelter that could be evacuated into in the event of an attack. I've taken the liberty of ordering construction over the bunker, and its disguise as a basement. I'd recommend sending more [illegible]—
