As of the 2001 India census, Muttuchira had a population of 14,303 with 7,022 males and 7,281 females.^[1] It is a quiet farming village with rubber plantations, coconut plantations, and paddy fields. The landscape is hilly and narrow and is inhabited by Christians and Hindus. Most people are employed in either the farming or service sector.

In ancient records, Muttuchira was recorded as Nayappilli. Muttuchira got its name from a small check dam (chira) constructed in earlier times to irrigate paddy fields. It currently has a hospital (Muttuchira Holy Ghost Mission Hospital), a bank, an ATM, a Village Office, a post office, multiple churches (Holy Ghost Church), Temples (Kunnasheri Kave, Trikke), a Government Polytechnic, a nursing school, a girls high school, boys high school, LP & UP schools, Government Ayurveda dispensary and market. Kaduthuruthy Railway Halt is in the village. The village is part of Kaduthuruthy Gram Panchayat and Kaduthuruthy Assembly constituency. Saint Alphonsa of India was brought up in this village. The majority population are Syro-Malabar Catholics and some protestant Christians, but many Hindus also live in Muttuchira harmoniously.

Holy Ghost Forane church, Muttuchira is one of the oldest churches in India. There is an ancient Pahlavi inscribed granite bas-relief cross found in Muttuchira. According to the local tradition, the Church at Muttuchira was founded in AD 510. It was probably located near the ancient open air rock cross at Kurisum-moodu, a little east of the present church dedicated to Mar Sleeba (syriac:sliba meaning Holy Cross). It is probable that a new Church was built in the present Church compound on the Eastern side in AD 1528 by Mar Denha and Mar Abo ( Mar Jacob Abuna) as narrated on the Muttuchita inscriptions. This Church was dedicated to Ruha D Kudisha- Holy Spirit. The Pahlavi inscribed granite Cross was transferred to this Church from the ancient Mar Sliba Church. Later, this sliba which was placed in the altar was covered by building a wooden raredos rathaal in front of it. In AD 1854-58 period, another Church was built in front the old Church dedicated to Ruha D Kudisha which is the main Church at Muttuchira today. In AD 1923, the old Rooha D Kudhisha Syro-Malabar Catholic Forane Church, Muttuchira on the eastern side of the present Church was renovated to rededicate it to Saint Francis of Assisi. During the renovations, the ancient Pahlavi inscribed Granite Sliva was rediscovered behind the wooden raredos-rathaal of the old church fixed to the eastern wall of the Madbaha. It was again neglected and transferred to the new Ruha D' Qudisha Church in a very unimportant place- back side of the wall of the facade in a corner, probably because of the interests of the Archaeological Department of the then Government of Travancore. Now, this invaluable monument of Saint Thomas Christians of Malabar has been placed in a side altar of the main Church.^[2]

Muttuchira inscriptions are early Malayalam inscriptions- Vattezhuthu- Nanam Monum- on a granite tablet found in Muttuchira. The 'Muttuchira inscriptions' are inscriptions narrating about the installation of the free standing Cross and the Pahlavi inscribed bas relief cross, The 'Muttuchira Sliba'. The inscriptions are on a rectangular granite slab in two sections divided by a vertical line in between. According to Mr. T. K. Joseph, this inscription must be of AD 1581 or later. This tablet has been the subject of extensive research by many scholars. This granite slab was found on the western wall of the ground floor room of the two storey building attached to the northern side of the old Church of the Holy Ghost. The upper story was used as the Priest's Home and the ground floor was used as the sacristy. Muttuchira Sliba, the Pahlavi inscribed Cross is an invaluable monument of the Christian community that was the symbol of veneration of the ancient Christian settlement of Muttuchira. Muttuchira inscription tablet is another landmark monument which narrates installation of the Mar Thoma Sliva in the altar and the open air Rock Cross of Muttuchira Church is historically important.^[2]
