5th Century? Roman’s? I don’t think so.
5th Century means the 400s. The Western Roman Empire fell in 476 AD, the Eastern Roman Empire fell in 1462.

The Western empire collapsed in the 5th century - around the time of this church and the eastern empire ruled an additional 300 years give or take in the middle east before Islam came and 1,100 years out of Constantinople and Antolia/Balkans.
