A Nail Can Tell a Tale
Did you know you can date an old building just by looking at the nails?
One of the best ways to get a rough idea of a structure’s age is by examining the hardware—specifically, the humble iron nail. These little slivers of metal have changed a lot over the years, and each style tells a story:
🔨Hand-Wrought Nails (Pre-1790s):
These were forged one by one by blacksmiths. Irregular in shape with square shafts and hammered heads, they’re usually found in the oldest buildings—especially 18th-century log homes, taverns, and early frontier structures.
🪚 Cut Nails (1790s–1890s):
Mass production began in the early 1800s. Cut from flat sheets of iron, these nails are rectangular with flat heads. By the mid-1800s, they were everywhere—from floorboards to clapboard siding. If you see these, you're likely looking at a 19th-century building.
🧱 Wire Nails (1890s–Present):
The modern round wire nail appeared in the late 1800s and took over by the early 20th century. If your old house is full of round nails, chances are it was built—or at least renovated—after 1900.

Whether you’re restoring a cabin or just poking around in your attic, keep an eye on the nails. Sometimes, the smallest details hold the biggest clues.
