Roman Catholic Church The cathedral has a temple-like exterior but a conventional church interior. Aspects of traditional Kerala architecture, temple architecture and Eastern (Syrian) Christian tradition were integrated into the design. The exterior design incorporates elements from the architecture of the old cathedral that it replaced. The cathedral’s interior has a depiction of biblical themes in stained glass. Three key premises that are shown through these biblical themes are: God in search of man, man in search of God, and man in search of the other. The stained glass images depict the story of the Good Samaritan, The Prodigal Son, The Parable of the 10 Virgins, Zacchaeus, Parables of the Lost Sheep and Coins, the Rich Man and Lazarus, and the Last Judgment; important incidents in the life of Jesus from birth until the resurrection.
