In a recent blog post Ferrell Jenkins wondered if anyone had photos of the rebuilt bema at Corinth. Since he covered the data and the significance of the bema I will just post the images here.
In looking south at the north side of the bema—little has changed. However, around the back, on the south side, there is a metal ramp that leads up to the top of the bema.
Above are the remains of a double apse Byzantine Church that was built on top of the bema. The two apses of the church face east—as is typical.
So indeed, it is possible to stand on the top of the bema — on which Gallio the proconsul sat in judgment of the apostle Paul (Acts 18:12–17).
