If you’re driving down I-77 near Wytheville, Virginia, you might spot a strange, tall stone square poking out of the trees near the New River. It looks like a medieval watchtower. Honestly, it looks like something out of a fantasy novel, not a 19th-century manufacturing plant. But that’s exactly what the Jackson Ferry Shot Tower is. It wasn't built for knights; it was built for lead. Specifically, for dropping molten lead hundreds of feet to make perfectly round bullets. It’s a marvel of frontier engineering that basically turned gravity into a factory tool.
Most people just pull over, snap a photo, and leave. They’re missing the point. The tower represents a time when Southwest Virginia was the industrial heartbeat of the American frontier. It’s one of only a handful of shot towers left in the entire country, and unlike the fancy brick ones you see in cities like Baltimore or Philadelphia, this one is rugged. It’s built from massive limestone blocks, some two-and-a-half feet thick. It was built to last, and it has.
The Physics of Falling Lead
The whole concept of a shot tower is sort of brilliant in its simplicity. Before this, people made "swan shot" or bullets by pouring lead into handheld molds. It was slow. The results were often lopsided. In 1782, an English plumber named William Watts realized that if you drop molten lead from a high enough point, surface tension pulls it into a perfect sphere as it falls. Think about a raindrop.
At the Jackson Ferry Shot Tower, they took this science and scaled it up. Thomas Jackson, an English immigrant, started the project around 1807. It took him five years to finish. Why so long? Because he didn't just build a tower; he dug a hole.

The tower itself is 75 feet tall. But that wasn't enough distance for the lead to cool and harden before hitting the bottom. If it hits the water while it’s still soft, it flattens out like a pancake. To get the necessary 150-foot drop, Jackson had his crew hand-drill a 75-foot shaft directly down into the solid limestone bedrock beneath the tower. Then, they dug a horizontal adit—basically a tunnel—from the banks of the New River to the bottom of that shaft.
So, a worker at the top would melt lead in a furnace, mix it with a bit of arsenic (to make it harder and rounder), and pour it through a sieve. The lead droplets would fall 75 feet through the air inside the stone tower, then another 75 feet through the dark shaft in the earth, finally splashing into a large kettle of water at the very bottom. A worker would then paddle a boat through the tunnel from the river to collect the finished shot. It’s wild to think about someone sitting in a dark, damp tunnel under the earth, waiting for a rain of boiling metal to stop so they could go to work.
A Mountain of Lead
You might wonder why Jackson built this thing in the middle of nowhere. It wasn't the middle of nowhere to him. The tower is located just a few miles from the Austinville lead mines. Those mines were some of the most important mineral deposits in the young United States. During the American Revolution, the lead from these mountains was used to supply the Continental Army.

Stephen F. Austin—yes, the "Father of Texas"—was actually born right near here because his father, Moses Austin, owned the mines for a while. The location was strategic. By building the Jackson Ferry Shot Tower right on the banks of the New River, Jackson could easily transport his heavy product by water or along the nearby Great Wagon Road.
The tower operated for about 70 years. It survived the Civil War, though it didn't play a massive role in it since newer manufacturing methods were starting to take over. By 1839, the Wythe Union Lead Mine Company took over operations. They eventually shut it down in 1876. After that, it just sat there. It became a relic. A very heavy, very tall relic that nobody knew what to do with until the local community and the state stepped in to preserve it.
Why it Still Stands Today
Stone doesn't rot. That’s the short answer. But the longer answer involves a lot of local pride. In the 1920s, the Daughters of the American Revolution took an interest in the site. Eventually, it became a centerpiece of the New River Trail State Park.

When you visit today, you can't go to the very top—safety regulations and the sheer age of the internal wooden stairs make that a no-go for the general public—but you can see the furnace area and peer into the depths. The craftsmanship is staggering. Those limestone blocks were hauled from nearby quarries and set without the help of modern cranes. It’s a testament to the grit of the Scotch-Irish and English settlers who populated this part of the Appalachian Mountains.
Modern Day Visiting Tips
The Jackson Ferry Shot Tower isn't just a monument; it's part of a massive recreational area. The New River Trail is a 57-mile "rail-to-trail" park that is incredibly popular for biking and hiking.
- Timing: The tower grounds are open year-round, but the interior is usually only open for tours during the summer months and on specific weekends in the spring and fall. Check the Virginia State Parks website before you make the drive specifically for a tour.
- The View: Even if the tower is locked, the view of the New River from the base of the tower is one of the best in the region.
- Accessibility: The walk from the parking lot to the tower is short but uphill. It’s paved, so it’s manageable, but it’ll get your heart rate up.
- The Tunnel: You can see where the horizontal tunnel meets the river. It’s often overgrown, but it’s cool to imagine the boats coming and going out of the base of the cliff.
What Most People Get Wrong
People often assume the tower was a fort. It’s an easy mistake. It has that "keep" look to it, and the small windows look like arrow slits. But those windows were actually for ventilation. Melting lead creates toxic fumes. You need a lot of airflow if you don't want your workers dropping dead before the lead does.
Another misconception is that the shot was used for muskets. While you could use it for that, the small, uniform pellets produced here were primarily "birdshot" for hunting. It was a commercial enterprise aimed at frontiersmen and farmers who needed to put food on the table.
The Jackson Ferry Shot Tower is a rare survivor. Most shot towers in the 1800s were built of wood and brick and burned down or were demolished as cities expanded. This one, tucked away in the Virginia highlands, survived because it was built into the very bones of the earth.
Practical Next Steps for Your Visit
- Check the Tour Schedule: Visit the Virginia State Parks official page for New River Trail State Park to see when rangers are on-site for interior demonstrations.
- Pack a Bike: Since the tower is at a major trailhead, the best way to see the area is to park at the Shot Tower lot and bike south toward Foster Falls. It’s a flat, easy ride with killer river views.
- Visit Austinville: Drive the five minutes down the road to Austinville to see the monuments dedicated to the lead mines and the Austin family. It completes the story.
- Photography: The best light for the tower is late afternoon. The sun hits the western face of the limestone and makes the whole structure glow against the green of the trees.
