Chelsea is an unincorporated community in Bethel Township in Delaware County, Pennsylvania, United States.

[3] A blacksmith had operated from that location since the time of the French and Indian War.

The original building was demolished in February 2013 and the operations were moved to a larger facility on Foulk Road.

The blacksmith shop is still run by the same owners since the early 1900s, the McKinleys.

On this land was founded Bethel hamlet, later known as Corner Catch (Ketch) and the village of Chelsea.
