Although founded in 1841, Dallas did not experience significant growth until 1873 when the Texas and Pacific (T&P) Railroad crossed the Houston and Texas Central Railroad (H&TC) near downtown. Securing these railroads led to a prolific building boom that has never fully ended, even during the Great Depression and subsequent world wars. Dallas's ability to sustain growth and development as a banking and commercial center led to the demolition of much of the early built environment, a trend that continues even today. Lost Dallas explores and documents those buildings, neighborhoods, and places that have been lost and even forgotten since the city's modest antebellum beginning.
