St. Mary's Orthodox Syrian Church (കല്ലൂപ്പാറ പള്ളി), situated at the heart of a small village called Kallooppara (on the banks of the river Manimalayar), Pathanamthitta District, Kerala, India is a prized possession of Malankara Sabha. The church has a legacy of around seven centuries, keeping its tradition and culture intact without compromising on its religious values. The church is an elegant representation of the beautiful shingled roof tops in the early Travancore style. The church is a perfect example of the ancient temple architecture and is a mystery the way it has overcome all the challenges of time. The sanctorium that is abstract in all aspects is a mystifying beauty of the ancient architecture, which has a keen and splendid blend of beauty and science in it.
