Drawing on years of archaeological and historical research, the mission church was the first public building reconstructed on San Luis's central plaza. The church measured 50 feet wide by 110 feet long and was built on an east-west orientation. It was a timberframe construction with a massive thatch roof. The main architectural features were the nave, the sanctuary, and a choir loft. The baptistry was located inside the front door on the left-hand side of the entrance.
