Alabama Had a Capital Before Montgomery — It’s Now a Ghost Town Drowning in Wildflowers

The GPS brings most visitors to a gravel turnaround at the end of County Road 9 in Dallas County, Alabama — and then stops. What stretches beyond the parking area looks, at first glance, like dense riverine forest. Walk fifty feet in any direction, though, and the geometry becomes unmistakable: rectangular depressions where foundation walls once stood, brick rubble arranged in orderly lines, and wide clearings following the path of streets platted nearly 210 years ago. This is Cahaba — Alabama’s first permanent state capital, its most consequential planning failure, and one of the most quietly layered historical sites in the American South.

The town at the confluence of the Cahaba and Alabama Rivers held the state’s seat of government from 1820 to 1826. Today, its permanent population is zero. Its ruins are maintained as Old Cahawba Archaeological Park by the Alabama Historical Commission, and every May and June, the surrounding river shoals erupt in rare aquatic wildflowers that draw visitors who never knew the town existed.

A Capital Built on the Wrong Ground

Alabama achieved statehood in December 1819, and lawmakers needed a permanent capital quickly. The site chosen — a wedge of land between two rivers, roughly 12 miles south of present-day Selma — seemed strategically sound. River access meant commerce. A central location meant political accessibility. The legislature convened at Cahaba in 1820, and the town grew fast, eventually supporting hotels, a newspaper, and brick storefronts along St. Andrews Street.

The rivers that made Cahaba attractive also made it dangerous. Seasonal flooding from both the Cahaba River and the Alabama River turned the capital grounds into wetlands during wet seasons. According to the Encyclopedia of Alabama, floodwaters repeatedly submerged the statehouse and surrounding blocks, making normal governance nearly impossible. By the mid-1820s, legislators were convening in buildings standing in inches of water.

In 1826, the Alabama legislature voted to relocate the capital to Tuscaloosa, citing the chronic flooding. Without state government anchoring it, Cahaba’s commercial infrastructure gradually collapsed. The town persisted as a small agricultural community through the antebellum era, but it never recovered the significance it briefly held.

Castle Morgan: A Civil War Prison at the Bend of the Alabama River

Whatever hope Cahaba had for revival ended in the wreckage of the Civil War. In 1863, Confederate authorities established a prisoner-of-war camp at the town’s old cotton warehouse, designating it Castle Morgan. The facility was designed to hold roughly 500 Union soldiers. At its peak, it held more than 3,000.

Conditions at Castle Morgan were documented in postwar testimonies compiled by Union veterans and Congressional investigators. Overcrowding, inadequate food, and the same flooding that had doomed the capital years earlier combined to make the prison extraordinarily difficult for its occupants. Unlike the more widely documented Andersonville facility in Georgia, Castle Morgan received comparatively limited historical attention in the decades following the war — a gap that historians have since worked to address.

When the war ended in April 1865, Castle Morgan’s prisoners were released and transported north by river. A significant number boarded the steamboat Sultana on the Mississippi River, packed far beyond the vessel’s legal capacity. On April 27, 1865 — just days after the Confederate surrender — the Sultana‘s boilers exploded near Memphis, Tennessee. More than 1,500 people died, making it the deadliest maritime disaster in American history. Many of the dead were former prisoners of Castle Morgan at Cahaba.
