The history of Kalpathy dates back to the 15th century when Brahmins from Tamil Nadu migrated and settled in this region. The village flourished under the patronage of the local rulers, preserving its unique cultural identity and traditions. The Agraharam houses, built in the traditional Kerala style, reflect the architectural influences of both Kerala and Tamil Nadu. Over the centuries, Kalpathy has remained largely untouched by modernization, retaining its old-world charm. The annual Ratholsavam festival, a centuries-old tradition, continues to be a major cultural event, attracting devotees and tourists alike. Today, Kalpathy stands as a testament to the rich cultural heritage of Kerala.
