The Dwadasalayam refers to the twelve sacred Siva temples in Kanyakumari district, Tamil Nadu, celebrated for symbolizing the rare integration of Saivism and Vaishnavism, the two major sects of Hinduism. These temples, located in Vilavancode and Kalkulam taluks, hold immense spiritual, historical, and architectural significance. The Sivalaya Ottam, a marathon pilgrimage conducted during Sivarathiri, connects these temples, attracting thousands of devotees annually. Each temple possesses unique features, including distinct architectural styles, ancient inscriptions, and mythological associations. The temples at Thirumalai, Thikkuruchi, Thirparappu, Thirunandikkarai, Ponmanai, Pannipaham, Thiruvattaru, Kalkulam, Melancode, Thiruvidaicode, Thiruppantricode, and Thirunattalam reflect a blend of Dravidian and Kerala architectural styles, with rock-cut carvings, copper-plated domes, and intricately sculpted mandapas. The temples also hold historical relevance, with references to Travancore kings, Jain influences, and Muslim invasions, highlighting their enduring legacy. The Sivalaya Ottam, which begins at Thirumalai and concludes at Thirunattalam, symbolizes a spiritual journey of penance and devotion. This abstract explores the historical, religious, and architectural importance of the twelve Siva temples, emphasizing their role in promoting religious harmony and preserving cultural heritage.
