Poomkavu is situated in the out-skirts of Alapuzha town. It belonged once to the parish Thumpoly. In the parish of Thumpoly there were about 200 families belonging to the community of the seven hundred. On 8th March 1855, 1 acre and 73 cents of land situated in survey No.325/14 B was donated by Mr. Kochako Thomas Valiaveettil for the construction of a Church. Rev. Fr. Jorris Alvarez Alumkal from Chellanam was the parish priest of Thumpoly. With the interest he had shown, the people collaborated and constructed first a thatched shed for devotional gatherings. People generously contributed. The materials for the construction of the Church and the parochial house were carried by the people from 5 km east, from the Vembanad lake-shore. The parochial house was completed first. The Church was completed in 1860. For the blessing of the Church Rev. Bernardine Baccineto of St. Teresa O.C.D., Vicar Apostolic of Verapoly was solemly received from the lake-shore. The Church compound was beautifully adorned with trees. Seeing the natural beauty of the place Bishop Exclaimed, "It is indeed, a Poomkavanam".
