452 AMDS Bldg 2300, March Air Reserve Base, California

Short summary

Building 2300 (linked to the 452nd Aerospace Medicine Squadron / medical group) has long been one of the March Field locations singled out for ghost stories and amateur investigations. Reports range from whispered voices and unseen footsteps to night-vision photos that investigators say show shadowy figures — and a persistent rumor that parts of the old medical complex once housed a morgue or “shackles” in a basement that fueled darker tales. 

Origins of the stories

March Field (now March ARB) is one of the oldest continuously operated U.S. airfields (World War I onward). Because the base housed medical facilities for many decades — including wards for infectious disease at various times — it's become the locus for tales connecting tragic medical history (sick children, deceased airmen) with restless spirits. Those historical uses help explain why people associate the medical buildings, including Bldg 2300, with hauntings. 

Notable eyewitness reports and investigations

1. Multiple first-hand anecdotes from current and former staff describe hearing voices, being spoken to by unseen female voices, or feeling watched while working late in Building 2300. A community-submitted page collecting haunt reports includes a detailed first-person account from an employee who said a small female voice called her name in a restroom as she was leaving. 
2. In the 2010s a series of base public-affairs pieces covered investigations by reservists and civilian ghost-hunting groups. Night-vision photos and infrared footage were published by March ARB public affairs showing images some investigators said resembled people or apparitions; base articles present the investigators’ interest while also noting many episodes were never definitively explained.

The “shackles” / morgue rumor

A widely repeated claim held that an old basement near the base hospital or medical buildings contained shackles or restraints (sometimes dramatized as “torture devices”). A March ARB public-affairs story which investigated the rumor found the objects were actually pipe supports and other mundane hardware — but the rumor persisted and was widely retold because it fits the darker, creepier narrative people expect in an old hospital. That mix of plausible history + mundane explanation is a common pattern in base hauntings. 

Media attention

Local news and TV crews covered paranormal teams’ work at March Field: NBC Los Angeles ran a segment about night-vision footage taken inside an old medical building on base that appears to show two figures, and the base’s own public-affairs site posted photos and write-ups about investigations. The March Field Air Museum and local paranormal groups have also hosted or publicized paranormal events and tours at or near the airfield. 

How to read these stories

Two practical points: (1) The base’s public-affairs coverage is unusually candid — it published investigators’ photos and interviews rather than dismissing the stories outright — which helped the tales spread. (2) Many of the most sensational details come from personal testimony on paranormal sites and social posts; those are valuable for documenting folklore but are not the same as verified historical records. Treat the accounts as a mix of oral history, personal experience, and occasional supporting images rather than hard proof of the supernatural.
