Welsh Congregational United Church of Christ, formerly known as First Welsh Congregational Church, is located in a rural area southwest of Iowa City, Iowa, United States.

Owen Evans led those that advocated for English services to found the Williamsburg congregation around 1860.

[2] For over 50 years it was the location for the annual meeting of the Welsh Congregational Church Association, known as the Gymanfa.

It was also the site for an annual Eisteddfod, a festival of oratory, poetry, and musical contests.

On the roof above the main entrance is a spire that rests on a square base and a hexagonal drum.
