The story
The Aralvaimozhi Pass, called Aramboly during the colonial period, was a strategic gap at the southern end of the Western Ghats, linking Venad and Travancore with the Tamil kingdoms to the east. Many invasions came this way. Around 1750, the Travancore general Eustachius De Lannoy built the fort as part of a defensive system with Udayagiri Fort, Vattakottai and the Travancore Lines. English East India Company forces passed through in the campaign against soldiers loyal to Velu Thampi Dalawa, and the fort was captured; sources give the date as 1809 or 1810. The town's name is sometimes explained as whispering wind, after the sound of this pass.
