Sparta’s geography made it susceptible to invasion. true or false

It would be true.

Sparta is located in the region of Laconia and was built on the banks of the Eurotas River. The valley of the Eurotas is a natural fortress, bounded to the west by Mt. Taygetus (2407 m) and to the east by Mt. Parnon (1935 m). To the north, Laconia is separated from Arcadia by hilly uplands reaching 1000 m in altitude. These natural defenses worked to Sparta's advantage and contributed to Sparta never having been sacked.
