There was an interesting story behind this chruch that in the year 1943 a Ship named Villiam B. Augustus, was thrown to a sand island due to heavy cyclone. Though they tried hard to rescue the ship consisting of 1000 tonnes by using all manpower, it was in-vain. The ship stayed for one year in the same place without an inch of moment. At that time, one engineer by name E.H.Swini was deputed from America for this purpose. He also tried and came to a conclusion that this task would not be possible with manpower. And he worshiped the Lord ‘ Mary Maa’ and all of sudden the ship moved from the sand island. In tribute of the Lord Mary Maa, the engineer and his wife constructed this church in yanam. This festivals can also be seen now in the hill temple behind this church.
