The marketplace in Acts 28:15. This was the place where Christians met the apostle Paul when he came to appear before Caesar. It was apparently named for Appius Claudius. He was the builder of the Appian Way. The Appian Way was a major highway from southeast Italy running northwest to Rome.
Around the forum was a region of swamp and marsh. It was notorious in the ancient world for bad water, mosquitoes, expensive taverns for travelers, nighttime noisy traffic of cargoes, and passengers on mule-drawn barges along a canal cut through the area. The Appian Way passes through the Appius Forum about 64 kilometers (40 miles) south of Rome.
