The Church of St. Michael and All Angels was originally a wooden chapel constructed in 1858 in Greenhill Village, Diego Martin.  However, when it began showing signs of decay and inadequacy for the growing population it was replaced by a stone structure which was consecrated in 1875.  Sometime between 1915 and 1923 the Parish was without clergy, it was then put under the care of All Saints Parish by Archbishop Parry of Guyana, acting on behalf of Bishop Richard Rawle, the first Bishop of Trinidad and Tobago.  When St. Agnes separated from All Saints in 1923, St. Michael was placed with St. Agnes under Rev. E.O. Buxo, Rector (1923-1956).  Bishop Arthur Anstey also looked after the Parish when he resided at the Boys Industrial School (now St. Michael School for Boys).

With the influx of the new residents of Diamond Vale, in addition to the parishioners from Bagatelle, Patna, Four Roads and Carenage, the Church had again become inadequate for the growing population.  Sometime in 1967 the Church through the Incorporated Trustees swapped a considerable portion of its lands at Greenhill Village with Government in exchange for approximately 53,000 square feet of land at Diamond Boulevard. Plans to rebuild were accelerated when an earthquake in September 1968 made the Church unusable and services had to be conducted in the adjacent Parish Hall.  The foundation stone was laid in April 1969 by the late Sir Solomon Hochoy, Governor-General of Trinidad and Tobago.  The building was completed in 1970 and dedicated in September 1971 by the Rt. Revd. Clive O. Abdulah, first local Bishop of Trinidad and Tobago.  It is interesting to note that this building was judged the best design for 1970 – a great credit to the Architect, Mr. John Gillespie.
