Artifacts from the original tavern - particularly the over 5,000 nails and the bricks - provided a great deal of information about how the tavern was constructed.
Researchers sorted the nails by size. Most were relatively short, which suggested that the building had a wooden shake roof. The large number of medium-sized nails indicated that the building had a wood floor and siding. Few large nails were recovered. This indicated that large timbers held together with mortise and tenon (tab and slot) joints, a common early 1800s building technique, constituted the building's framing.
The tavern's foundation bricks had a slight “frog” or indention on one side. They are identical to the bricks used in buildings along Center Street in Bowling Green, which is located about 30 miles to the south. Perhaps bricks used in Bell's Tavern were made in Bowling Green, and then brought to the tavern site.
