One of the picturesque islands that form a part of Kochi, Vallarpadam is best known for the Vallarpadam Church or the Basilica of Our Lady of Ransom. An ancient church that has been given the status of a basilica, it is one of the most prominent spiritual sites in Ernakulam district. The pristine white structure was built by the Portuguese in 1524 and is dedicated to Holy Mary or Vallarapadath Amma, as she is fondly called here. The church houses an image of the Virgin Mary that is believed to have been brought by the Portuguese. The best time to visit is during the feast of Vallarapadath Amma, a week-long event that is held on September 24.

Initially, the church was called the Church of the Holy Spirit, however, it was destroyed in a flood in the 17th century and a new church was set up at the same spot in the year 1676.
