Our Lady of the Rosary Catholic Church was founded in the mid-1800's when a small chapel was built at the juncture of Canal Harang and Bayou Lafourche. In 1873 a second church, which served the surrounding community of Larose and all of South Lafourche, was erected on the present site donated by Octave Harang. Rev. Hyacinthe Brindejone was the pastor. The present structure was erected in 1933 under the leadership of Rev. Charles Tessier. The adjacent cemetery has served the parish for over 100 years.
