The story

How Leavenworth came to be

From Wikipedia’s history of Leavenworth.

Read it all →

Leavenworth was laid out in 1818 in a horseshoe shaped bend of the Ohio River, directly under a large bluff called Mt. Eden. The bluff forms part of the Indiana Ridge and faces directly across the river toward Kentucky. "Old Leavenworth" (the original town, now practically abandoned) was almost completely wiped out by the huge 1937 Ohio River flood, as it was built directly on the floodplain.

The town was founded by Zebulon Leavenworth and his brother Seth, natives of Connecticut.

In 1824, a wood yard was established in the town to provide fuel to steamboats, and David Lyon had a boatbuilding industry here in 1830. The Whitcomb brickyard was also a flourishing industry.
