Traditional belief of Saint Thomas Christians of Kerala is that Thomas the Apostle landed in or around Kodungallur in the middle of the 1st century and founded Seven Churches, or Ezharapallikal: Kodungallur, Kollam, Niranam, Nilackal (Chayal), Kokkamangalam, Kottakkayal (Paravoor), Palayoor (Chattukulangara) and Thiruvithamcode Arappally – a "half church".
Kottekkavu (N. Parur) and Kokkamangalam / Pallippuram (Cherthala) are two places where St Thomas established churches in the first century.
