Statement of Significance (as of designation - October 12, 1993):
Dealey Plaza, built 1934-40, serves as Dallas' western gateway and was the focus of civic pride prior to the tragic event that unfolded on November 22, 1963--the assassination of President John F. Kennedy. The Dealey Plaza Historic District is one of only two extant Presidential assassination sites in the United States. Included in the district are the plaza and the Texas School Book Depository, which now serves as the seat of county government. An exhibition on the legacy and assassination of President Kennedy is located on the sixth floor.
