Thrikkannamangal has its own Kathakali Museum, which is situated in Thottam Junction. Kathakali is a dance form that originated in Kerala ^{[citation needed]}.

One of the unique points of modern history tied to Thrikkannamangal is that it served as the launching pad for the Pentecostal movement that has now spread throughout India. American independent missionary George E. Berg received baptism of Spirit at Azusa street mission in 1908. He came to Thrikkannamangal along with other missionaries during 1909 and proclaimed the first Pentecostal message in the 20th century. Due to the objection of co-missionaries he came during the year 1910 and 1911 along with native missionary Cummins of an Anglo Indian and preached petecoatal message. All these conventions are facilitated by Kalloor family especially Kalloor Chacko one of the patriarches of the family. George E. Berg brought Robert Cook to Bangalore during 1913. The American missionary, Robert F. Cook, was received into Kottarakara by the late Kalloor Chacko, the patriarchs of the Kalloor family in Kottarakara during 1921. The name of the first Pentecostal church established by Cook at Thrikkannamangal was named as Malankara poorna suveseha Sabha and now it is known as Malankara Church of God, Thrikkannamngal. This is the first Pentecostal Church in Thrikkannamngal. Beginning his work in Thrikkannamangal, Cook later moved to Mulakuzha and established the headquarters of the Indian Pentecostal Church of God there. The founders of the India Pentecostal Church as well as many other Pentecostal organizations were co-workers with Cook in the early days, parted him and formed separate Churches for political or doctrinal reasons. The oldest registered Pentecostal church in India is located in Thrikkannamangal. Gandhinagar is a part of Thrikkannamangal which is a beautiful agricultural place ^{[citation needed]}..

Bethel AG CHURCH:

Thrikannamangal is one of the earliest places where the true Pentecostal experience as a result of the overflowing power of Holy Spirit that was spreading all over the world was proclaimed.

Rev. George Berg  accompanied some foreign missionaries to the 1909 conventions and preached about the power of the Holy Spirit which he had received at United States.

Fascinated by the Pentecostal truths, Pallikkizhakkethil Luckose ,  Anazhikath Mathaichan ,  Kochukkizhakkethil Kuttiyachan,  Ammankotte Chacko Yohannan , and  Kizhakevila Panavela House  Chackochan bought some land and built a small shed for worship.
