Knoxville (WVLT) -- 1792 was a big year.
The U.S. Postal Service was established, Kentucky became the 15th state, and James White, Knoxville's founder, shaped the city with the help of the turnip.
It was in 1792, four year's before Tennessee became the 16th state, that White helped build First Presbyterian church.
The land it was built on just happened to be his turnip patch.
On Sunday, First Presbyterians congregation remembered the last 215 years during their Turnip Patch Celebration.
The church is Knoxville's oldest.
"We have been here so long that I think people kind of take us for granted," said Doy Barron, who organized the event. "But we have a very young up and coming congregation and we have a wonderful new minister coming in next month, so we are very proud of the church."
The Turnip Patch Celebration started with Sunday morning's worship which featured music from a tenor in the Metropolitan Opera
In the afternoon, there were concerts with bag pipers, horse and buggy rides and guided tours of the church's historic grave yard.
