St. Thomas Monastery was founded in 1890, canonically erected in 1895 and raised to the status of a formed house (Priorate) in 1908.
During the schisms of Rockos and Melus a good number of Catholics in the northern parts left the Church and joined the schism. This was considered to be due to the absence of a Religious house in those areas. It was this idea that inspired the foundation of the house at pavaratty.
The high school was started in 1905 under very adverse circumstances, facing strong oppositions from the Basel Mission and Board Schools at Chavakkad. It was due to the influence of Fr.
