The story

How Unionville came to be

From Wikipedia’s history of Unionville.

Read it all →

A Late Woodland village that was occupied between AD 1200 and 1600, now known as the Fisher Farm site, is located along Bald Eagle Creek on Unionville's western edge.

The village was laid out in 1848 at the site of temporary lumber camps in the Bald Eagle Valley. Unionville became the third borough incorporated in Centre County in 1859, and became a station along the Bald Eagle Valley Railroad in 1864.

In the 1860s a pink Methodist church was built in the borough. In 2015 it became an art exhibit known as Marry's Pink Church.

In 2024 Unionville flooded due to heavy rains from Tropical Storm Debby.
