Recent research has found a plausible position for Raphana at the northeastern-edge of the Decapolis region. This fits also to the history of Flavius Josephus, who describes the forts around a place called Raepta, which is very plausibly the predecessor settlement of Raphana. For the mentioned connection see also the Pleiades Database for "Raphana" at stoa.org.
The research suggests that Raphana may be located near the northeastern edge of the Decapolis region, and this finding supports Josephus' historical account, which describes forts around a place called Raepta, which is believed to be the precursor settlement of Raphana.  This connection is further supported by the Pleiades Database for "Raphana" at stoa.org.
