Current Status: The Tomb is unoccupied at all times
The Tomb of the Unknown Soldier, located at Arlington National Cemetery, is an empty marble structure. It houses no remains, no casket, and no person at any time. The crypt is sealed, and the space is maintained as a memorial rather than an occupied grave. There is no schedule placing anyone inside; the Guard is posted outside the Tomb during public hours as a ceremonial sentinel, not as an occupant or caretaker within it.
What the Tomb actually contains
Across the memorial plaza, the crypts hold the unidentified remains of service members from World War II, Korea, and Vietnam, interred with full honors. Each crypt sits empty of remains except at the precise moments when remains believed to be unidentifiable are transferred for permanent entombment. Once a new unknown service member is selected and interred, the previous set of remains is respectfully reinterred in a separate cemetery or cremated per family preference. The Tomb structure itself therefore remains empty, housing only the memorial slab and symbolic materials placed during ceremonies.
How the Guard rotation works
The 3rd U.S. Infantry Regiment (The Old Guard) operates the Tomb Guard Identification Program. Sentinels serve a voluntary tour, living in barracks adjacent to Arlington House and performing meticulous drills that number in the precise, numbered steps of the Changing of the Guard. A Relief Commander oversees each watch, coordinating 24/7 coverage with no exceptions. Known details include:
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Guard posting schedule | Continuous, 24/7/365; watches are typically 30 minutes in summer, 60 minutes in winter | Official Arlington National Cemetery and The Old Guard documentation |
| Eligibility and training | Volunteer soldiers from the 3rd U.S. Infantry Regiment must meet height, weight, uniform standards, and pass tests on Guard history and protocol | Military unit SOP and ceremonial unit records |
| Interment events at the crypts | Remains are placed into crypts during a private ceremony; the Tomb is physically empty during and between ceremonies | Ceremonial protocols and Arlington National Cemetery public guidance |
Addressing common questions and misconceptions
Misunderstandings arise because the Tomb is often described as housing unknown soldiers while the structure itself remains empty. A brief comparison clarifies typical confusion points:
- Casket present vs. memorial-only: The Tomb is a marble memorial with a marble slab; no casket is placed inside during normal operations.
- Sentinel inside vs. posted outside: Guards stand watch outside the Tomb, facing the Unknowns, and execute precise turning and marching rituals as observers of the memorial, not occupants of it.
- Temporary occupancy during ceremonies: During an Unknown Soldier interment, the Tomb area may host the ceremony at the slab, but the crypt is prepared and remains empty until remains are formally committed.
Historical context and continuity
Since the Tomb was first dedicated, the intent has been to honor unidentified service members without implying that the structure itself serves as a permanent resting place. Ceremonial interments have taken place at varying intervals, with gaps during periods of identifiable recovery or when remains are repatriated. Empty crypts alongside occupied ones reflect ongoing practices that prioritize dignity, identification advances, and family wishes. Military policy maintains that the Tomb memorializes unknowns regardless of whether physical remains are present, reinforcing the symbolic nature of the site.
Visiting and respectful observation
Visitors observe the Tomb from perimeter walkways and viewing areas. Photography, silence, and formation conduct are expected to preserve the solemn atmosphere. Because the Tomb is unoccupied, there is no opportunity to see anyone inside; the ritual lies in the Guard’s precise conduct and the memorial’s enduring presence. For planners, understanding timing around ceremonies and changing the Guard improves respectful engagement and avoids disruptions during private interments.
