Trinity Episcopal Church was founded in 1834 and is the third oldest church in the Diocese of Alabama. The congregation met in homes and a small log building until 1850 when a frame building was constructed on this lot given by the Lyon family.

Federal Troops burned the framed building during the occupation of Demopolis after the Civil War. The Nave of the present was completed in 1870 from plans drawn up by Edward S. Potter, a New York architect who also designed the chapel at West Point and other famous 19th century church buildings. The transepts were added in the 1890's and the bell tower in 1910. Trinity is one of the finest examples of Victorian Gothic Church architecture in the United States.

The Tiles in the Narthex:  These tiles were made in England in the 1830's and were in the old rectory around the fireplace of the living room. They were placed in the narthex when the area was remodeled in 1987. The tiles to the left of the doors are scenes from the Old Testament. The ones on the east wall are from the Parables of Jesus.

The Bishop's Chair:  This chair was made for Leonidas Polk when he became Bishop of Louisiana in the 1840's. Bishop Polk spent much of the War between the States in Demopolis as a Confederate General, and his family gave the chair to Trinity.

The Pipe Organ: Parts of this organ date back to 1870 when the church was built. It was enlarged and restored in the 1960's and again in 1989. In 2003, it was completely restored by Redman Organ Company with the addition of new ranks of pipes. It is now a 17-rank instrument with classical voicing.

The Eagle Lectern:  Hand carved of walnut; William Mecklenburg Polk, the son of Bp. Polk, gave this lectern in memory of his predeceased children: Leonidas and Serena Polk.

The Reredos:  This was hand-carved in England and was gift to Trinity from the Rev. William Stickney of Faunsdale. The dossals in the walnut arches are hand carved and gold leaf, given in memory of Joseph M. Eskridge.

Trinity's Stained Glass Windows:  There are about 80 stained glass windows in Trinity Church and the Parish House. They reflect a wide range of subjects and periods of design. Trinity is a treasure house of stained glass artistry of the 19th and 20th century.

The Floral Cross window is thought to be a work of Tiffany or one of his proteges. Windows of this type are distinctive for their use of opalescent glass, a technique pioneered by Tiffany.
