Yanam is having 300 years of History which is being well known as a 'French yanam' This region was ruled by French People for 300 years. The monument of the Catholic Church' French rulers is the 'The rememberance of the French Rulers is linked with this church. This church was built under Eeroupian style.There is is none other church available like this church. The furniture,decoration articles were imported from France.  This church was built in the year 1846 by the Franch missionarie.The  foundation stone was laid down by Father Michel Lecnam and he was died in the year 1836 April 30th without completion of  the church work. For his rememberance a culvert was fixed in this church.The church work was completed in the year 1846. There is another special attraction in this church is that a hill temple was built in this premises of the church by the french rulers,and there is another hill temple behind the church which was built by the English engineers.

There was an history 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 invain. 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 worshipped 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 history can also be seen now in the hill temple behind this church.

From then, every year in March, a major festival is being celebrated. Devotees from various neighbouring places used to come here and worship the Lord Mary Maa. The very remarkable thing is that the devotees are not only from the Christians but also Muslims, Hindua and other religions.
