Before European settlement, the area that now includes Lower Macungie Township was inhabited by the Lenape Indian tribe.

They hunted here, and are known to have had a few small seasonal villages and jasper workshops close to streams and springs.

Jasper from their quarries outside present-day Macungie and Vera Cruz was traded throughout North America.

They cleared the scrub and forests, planted crops, raised livestock, and continually expanded their holdings.

Most of what they produced fed their families and their hired and indentured servants, but some crops were grown for their cash value.

Eventually they raised enough money to buy land warrants in Philadelphia from the proprietors, including William Penn's heirs.
