Trinity is located in northwest Morgan County in the north-central part of the state, just west of the city of Decatur. It has a mayor/city council form of government.
The Trinity area began to be settled as early as the 1810s as plantation owners built homes on the elevated site to escape the plague of mosquitos in the lowlands where their plantation houses stood. A Methodist church had been established by 1820. Development of schools lagged behind, as most of the large landowners had private tutors for their children. The first public school in Trinity evolved out of one of the planation schools and in 1874 opened as the private Mountain Springs School. It became Lile College in 1900, after the family that started it.
Trinity's first post office was established in 1848 but closed in 1853. The area was known for its rock quarries in its early years and also served as a stagecoach stop. The post office was reopened in 1866, and the town took on the name Trinity Station. Trinity incorporated in 1901 and changed its name back to Trinity in 1903.
