Sixth Floor Museum History: From Book Depository to Museum

Dallas, Texas · Filed from the source ledger·Filed 2026-11-04

The Sixth Floor Museum at Dealey Plaza sits inside the former Texas School Book Depository at 411 Elm Street in downtown Dallas. It exists because the building's sixth floor is where investigators found key evidence after President Kennedy was shot on November 22, 1963. The county bought the building in 1977, a civic group spent years turning it into an exhibit, and the museum opened on February 20, 1989 (Texas State Historical Association). This guide walks through that history in order: the warehouse, the day itself, the near-demolition, the opening and what the museum has grown into.

A warehouse before it was a landmark

The building most people know as the Book Depository was a working commercial warehouse long before 1963. It was rebuilt by 1903 and housed a plow company, a grocery wholesaler and a textbook distributor over the decades (Texas State Historical Association).

That ordinary past matters for understanding the site. Nothing about the structure was designed to be a memorial. It stood at the edge of Dealey Plaza because that was where Dallas's old downtown warehouse district met the courthouse square. If you want the street's longer story, from cotton market to the most photographed block in Dallas, our piece on Elm Street's history covers it.

By 1963 the building worked as a distribution hub for school textbooks and held offices for education publishers. The assassination happened during that tenancy (Texas State Historical Association). The Warren Commission report describes most employees as working for those publishers, with the balance, including a 15-man warehousing crew, employed by the Texas School Book Depository Company itself (National Archives). In other words, on that Friday it was a busy workplace with people eating lunch and stacking boxes.

What the official record says happened on the sixth floor

The sixth floor became historically significant because of what investigators found there. Here is what the Warren Commission's 1964 report states, kept to the documented claims.

The window. The Commission concluded that the shots that killed President Kennedy and wounded Governor Connally were fired from a sixth-floor window at the southeast corner of the building (National Archives, Chapter 1).

The cartons. Around 1 p.m., Deputy Sheriff Luke Mooney noticed a pile of cartons in front of the southeast corner window (National Archives, Chapter 3).

The rifle. At 1:22 p.m., Deputy Sheriff Eugene Boone and Deputy Constable Seymour Weitzman found a bolt-action rifle with a telescopic sight between rows of boxes in the northwest corner near the staircase. The report says the weapon was left undisturbed until Captain Fritz and Lieutenant Day arrived and it was photographed where it lay (National Archives, Chapter 3).

The cartridge cases. Dallas police found three spent cartridges on the sixth floor, and firearms experts later analyzed them along with a nearly whole bullet and bullet fragments (National Archives, Chapter 3).

The rifle's trail. The report says the FBI traced the rifle to a Chicago mail-order house by 10 p.m. that night, and that it had been ordered in March 1963 and shipped to a post office box in Dallas rented by Oswald (National Archives, Chapter 1).

These are the Commission's findings and descriptions of evidence, and the museum itself takes a careful stance on them, as we explain below. For a minute-by-minute treatment of the day, see our reconstruction of the events of November 22, 1963, and for the plaza's geography, our evidence-first account of Dealey Plaza.

From controversy to county ownership

The Depository Company moved out in 1970. The empty building then became a point of controversy in Dallas, with demolition threatened and an arson attempt in 1972. Dallas County acquired the structure in 1977 as part of a bond package (Texas State Historical Association).

The city's own ambivalence is part of this history. For years, many residents wanted the building gone, and the idea of turning it into a public exhibit was far from obvious. Public ownership is what kept it standing.

The county first used the structure for offices. Its lower five floors became Dallas County government offices in 1981 (Texas State Historical Association). For the broader context of how Dallas absorbed the event in the decades after, our article on Dallas in 1963 and after fills in the city side.

How the museum came together, 1977 to 1989

Creating an exhibit took twelve years. Lindalyn Adams and Conover Hunt led the effort, and the exhibit opened on February 20, 1989 (Texas State Historical Association). That was Presidents Day that year, and the original exhibit was titled John F. Kennedy and the Memory of a Nation.

The first exhibit was developed with the design firm Staples and Charles. It included recreated evidentiary areas: the so-called "sniper's perch" and the location where the rifle was found (Texas State Historical Association). The museum built these recreations from crime-scene photographs, which is why they look the way they do rather than as dramatic reinterpretations.

The museum's stated approach

The exhibit explores Kennedy's life, times, death and legacy, including assassination evidence and eyewitness testimony. It does so without drawing conclusions about the Warren Commission's findings or the possibility of a conspiracy (Texas State Historical Association). That restraint is a defining feature of the place. Visitors are given documents, photographs, film and testimony and left to weigh them.

Growth since opening

The museum did not stay a single exhibit. In the mid-1990s it moved toward extensive archival collections and oral history projects, and it later expanded to occupy the seventh floor, which opened in 2002, and ground-floor facilities in 2010 (Texas State Historical Association). County offices moved out of the building in 2021 and 2022 (same source).

The collection now includes more than 90,000 artifacts, images, documents, audio and visual recordings and other documentation of the assassination and President Kennedy's legacy (Portal to Texas History). Its materials also reach beyond Dallas. The National Archives holds donated Sixth Floor Museum materials that include Parkland Memorial Hospital records and correspondence, plus records concerning John F. Kennedy, Lee Harvey Oswald and Jack Ruby (National Archives).

The building on screen

The site has also shaped popular memory through film. According to the building's Wikipedia entry, Oliver Stone's 1991 film JFK was allowed to film there only after five months of negotiation, with strict limits on how many people could be in the sniper's perch area. That detail is a reminder that the room has been treated as a protected historical space for decades, not a backdrop.

Visiting the museum with the history in mind

When you walk the exhibit, it helps to know that the floors you pass through belonged to a workaday warehouse before they became a gallery. Read the building first, then the exhibit. Look at the window corner with the recreated perch and compare it to the Commission's description of the cartons and the rifle's location in the northwest corner.

A few ways to get more from the trip:

Walk the plaza outside before you go in, so you know where the building sits relative to Elm Street. Our Dealey Plaza field guide and JFK sites walk are built for that.

Confirm current hours, ticket prices and timed-entry rules on the museum's official site before you go, since these change.

If you travel often and plan around museum admission, guides to free museum days in other cities show how reservations commonly work for popular venues.

Perspective

We built our room around a simple conviction: the Sixth Floor's history is strongest when you handle the evidence yourself. The building's story, from warehouse to crime scene to county property to museum, is a story of documents, photographs and testimony, and that is exactly the material our puzzles use.

Most escape rooms ask you to suspend disbelief. We ask the opposite. Every puzzle in Escape from the Sixth Floor is anchored to public records such as Warren Commission findings, archival scans and period artifacts, and we work to separate documented fact from unverified theory. When you reconstruct the timeline of November 22 in sixty minutes, you are doing a small version of what the investigators, and later the museum's curators, had to do: decide what a source actually supports.

That is why we think a visit to the museum and a session in our room complement each other. The museum gives you the long view and the collection. We give you a team, a clock and a stack of primary documents, and ask what you can prove.

Is the Sixth Floor Museum where Kennedy was shot from?

The museum is inside the former Texas School Book Depository at 411 Elm Street. The Warren Commission concluded the shots were fired from a sixth-floor window at the building's southeast corner (National Archives). The museum itself presents the evidence without drawing conclusions about the Commission's findings or about a conspiracy.

When did the Sixth Floor Museum open?

It opened on February 20, 1989, after a twelve-year effort led by Lindalyn Adams and Conover Hunt (Texas State Historical Association). Dallas County had bought the building in 1977. The original exhibit was titled John F. Kennedy and the Memory of a Nation.

What was the building used for before the museum?

It was rebuilt by 1903 and housed a plow company, a grocery wholesaler and a textbook distributor. In 1963 it served as a school-textbook distribution hub and held publishers' offices (Texas State Historical Association). Dallas County later used the lower five floors for government offices starting in 1981.

What does the museum's collection include?

The collection holds more than 90,000 artifacts, images, documents and audio and visual recordings about the assassination and Kennedy's legacy (Portal to Texas History). Some donated materials, including Parkland Memorial Hospital records, are also held by the National Archives.
