The Parish of St. Mary, Tacarigua, began in 1826 with the formation of a congregation at Tacarigua through the combined effort of the Reverend Gentlemen J. H. Keston and John Pinder who established a small Missionary outpost at the village Police Station. From this outpost, pastoral advice and conversions as well as the sacraments of baptisms, marriages and burials were undertaken.
Plans for building the first parish church started around 1841 with the contributions from ex-slaves and Roman Catholics on six acres of land donated for the mission of the church by a wealthy planter – William H. Burnley, owner of the Orange Grove Estate. The foundation stone was laid in 1842. The church building was constructed in the same year by Reverend I. Hamilton and was consecrated in 1843 by Bishop Parry. The Feast of Title, the Nativity of the Blessed Virgin Mary is observed on September 08.

The Church Building with a seating capacity of three hundred and fifty in the main is still as it was redesigned and rebuilt in 1901 by the Rev. W. M. Springer, making it the second oldest church building in this Diocese. Repairs to the roof were undertaken in 1968 and 2004, the stained glass windows were restored in 1998 and the belfry and steeple were renovated in 2001.

The Children's Home originally called "The Orphan Asylum and Industrial School for Coolie Orphans" was established in 1837 as an Anglican Mission. The wooden Rectory, located on the Eastern Main Road, Tacarigua, was commissioned in 1844.
