Cahaba is a ghost town in Dallas County, Alabama. The nearest town is Selmont-West Selmont, about 11.2 km (7.0 mi) away (Cahaba lies SW of town). It is listed on the National Register of Historic Places.
Cahaba, also spelled Cahawba, was the first permanent state capital of Alabama, United States, from 1820 to 1825. It was the county seat of Dallas County, Alabama until 1866. Located at the confluence of the Alabama and Cahaba rivers, the town endured regular seasonal flooding. The state legislature moved the capital to Tuscaloosa in 1826. After Cahaba suffered another major flood in 1865, the state legislature moved the county seat northeast to Selma, which was better situated. The former settlement became defunct after it lost the county seat, because it lost associated businesses and jobs. Many of its people moved to the new county seat. Cahaba declined rapidly, although it had been quite wealthy during the antebellum years. It is now a ghost town and is preserved as a state historic site known as the Old Cahawba Archeological Park.

Milky Way & night sky
From Cahaba, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.3 hours on a moonless night), and the core peaks around 29° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), good enough for detailed Milky Way images.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.45 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show October as the clearest month (about 41% average cloud cover) and February as the cloudiest (60%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this ghost town
- Look for details: door hinges, faded signs, square nails and window frames tell the story.
- Leave everything as you found it; removing artifacts from public land is illegal.
- Respect private property and closures: many ghost towns are on private land or protected historic sites — never enter unstable buildings.
- For interiors with windows, blend two exposures (one for inside, one for the view) instead of relying on HDR alone.
- Old buildings under the Milky Way make strong night images in dark rural skies.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: High-elevation mining towns are reachable mostly from June to October; desert ghost towns are best in spring and autumn.
Suggested gear: Wide-angle lens, Tripod, Headlamp, Sturdy boots. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
Private property: Many ghost towns sit on private land or protected historic sites. Respect signs, never enter unstable buildings and leave artifacts in place.
