St. Mark Baptist Church was erected in 1877 at Chamberlin. It began as a barge structure that had spent 44 years on the Mississippi River before being pulled from the river and taken by wagons to this site. More than 150 members from Smithfield, Orange Grove, Winterville, and Erwinville Plantations started the church. Its cornerstone contains the names G. McQuillon, J. Tackneau, L. Payne, P. Huntley, C. Payne, E. Savage, and R. Williams. It was the first school for many black people in the area, with Louise Viola Logan as the only teacher for all grades. To date, nine pastors have ministered to members from the northern part of West Baton Rouge Parish. The church serves the community as a voting site, storm shelter, meeting place, and food pantry. The property was originally purchased from the Devall family and paid for by member lease for 100 years. St. Mark has buried many people in its two cemeteries, Ashland and Orange Grove, the latter donated by the Laws family. Ashland Cemetery, located behind the church, was donated by the Henry Devall family, and members of the Devall family are buried there along with black members of the community and St. Mark Baptist Church.
