Bible Geography · Asia Minor (modern Turkey) · c. 189 BC – AD 1390
Philadelphia (Asia Minor)
Description
Philadelphia was founded around 189 BC by Attalus II of Pergamum, who named it for his brotherly love for his predecessor. It sat on the eastern edge of a fertile plain and served as a gateway city into the highlands of Phrygia, giving it a strategic role as a 'door' to the East.
Significance
Christ's letter to Philadelphia in Revelation 3 is entirely encouraging, recognizing a church of little worldly power yet great faithfulness. The 'open door' imagery speaks to missionary opportunity, while the promise of the 'new Jerusalem' and God's name written on the faithful connects personal endurance to eternal glory.
Key Events
The destructive earthquake of AD 17 that devastated the city, from which it was rebuilt; Christ's promise of an open door and protection from the hour of trial (Revelation 3:7–13); the city's resistance and final fall to Ottoman forces in AD 1390, long after other Asia Minor cities fell.
Modern Context
Philadelphia survives as the modern Turkish city of Alaşehir in Manisa Province. A Byzantine-era church column still stands in the town center as a visible reminder of the ancient church. The city is surrounded by vineyards and remains agriculturally productive.
