The Sunday festivities at Pencader Presbyterian Church are slated to begin at 2 p.m.
The church was founded in 1710 by Welsh immigrants; the original meeting house burned and a second building was erected in 1782. The current building has been in place since 1852.
The church was once used as a hospital after a Revolutionary War battle.
People who attend the celebration can attend a 4 p.m. worship service, followed by a supper at 5:15 p.m. All events are free.
