If you mean the Galatia in the Bible, it was in what is now the
country of Turkey. Galatia was an area in the highlands of central
Anatolia (now Turkey). It was bounded on the north by Bithynia and
Paphlagonia, on the east by Pontus, on the south by Lycaonia and
Cappadocia, and on the west by the remainder of Phrygia. Galatia
was originally home of the ancient civilization of the Hittites,
but came to be occupied by Gallic Celts in the 3rd century BC,
hence Galatia, or "Gallia of the East."
