Central Prison, Viyyur, is situated in Thrissur in Kerala state of India and is authorised to accommodate 520 prisoners. It is one of the four central prisons other than Poojappura, Kannur and Tavanur, situated in Kerala state. It is one of the most important correctional and detention centers in the state. As per Kerala Prison Rules, the prison is meant to detain convicted habitual prisoners on a long-term basis. The prison has separate buildings designated as special jail and sub-jail meant for short-term convicts and people on trial, respectively. History Thrissur was the capital of the Kochi Kingdom for a long time hence the State Prison was located here. The original Thrissur Prison existed in front of Sri Vadakkumnathan Temple around 300 years ago. At the request of the prisoners, "Kudamattom" was conducted at the prison during the festival of Thrissur Pooram during the reign of H.H. Sakthan Thampuran, the Maharaja of Kochi. In 1914 the temple authority requested to shift the prison and consequently it was demolished and shifted to Viyyur. Almost 1,000 acres of land from the property of H.H. Parukutty Nethyaramma Consort Queen of Kochi and Wife of Maharaja Rama Varma were handed over to establish the new prison at Viyyur. Later much of this original land went into use for other state purposes such as All-India Radio, Television, a police training facility, Fire Force center etc. After independence, the Government of Kerala, took over the facility and converted to a Central Prison intended to detain long term prisoners. Property The prison originally had almost 1000 acres of land; however, several state establishments were subsequently established on its premises. This reduced the land available for exclusive use by the prison to 147 acres. Out of which, the Central Jail occupies a space of 17 acres. The remaining land is used for other prison facilities and buildings. Central Jail The Central Jail is located in the center of the entire prison property, separated from the rest of the area via a circular perimeter wall almost high, with a central watch tower at its center. There are six blocks for confining prisoners situated as the petals of a flower pointing towards the office block. Among the blocks A, B, C and D are made for cellular confinement having 44 cells each. F and E blocks are dormitory type having four compartments and the latter is used for female prisoners
