Founded in the 1860s, Granbury started as a square and log cabin court house. Many of the buildings on the square are now
registered historic landmarks, including the Granbury Opera House, which still hosts Broadway productions. The city name originated
from the Confederate General Hiram B. Granberry. Some scholars believe his name was misread as Granbury on a document, thus the city name is spelled differently, but recent
findings have concluded that Granberry chose to spell his name Granbury. Recent expansion of the city was possible from the damming of the Brazos River in 1969, which formed Lake Granbury, a long, narrow lake which flows through the city.
Granbury and Hood County are rich in Texas history. David (Davy) Crockett's wife, Elizabeth, settled in Hood County following the Texas Revolution against Mexico. Crockett, as well as other Alamo
participants, received land grants. The Crockett family received land in what is now Hood County. Elizabeth Crockett is buried
in Acton State Historic Site, the smallest state park in Texas. A large statue of Elizabeth Crockett marks her grave site. Several of Crockett's descendants
still reside in Hood County.
John Wilkes Booth, according to Granbury legend, moved to Hood County and assumed the name of John St. Helen. There is
a store on the historic town square that is still called St. Helen's.
