The Church of the Holy Trinity is located in Embleton, Northumberland, England. The church, dedicated to the Holy Trinity, is west of the village. Built in the form of a cross, it consists of a two aisle nave, a clerestory, a chancel, a porch, and a chantry chapel. It has a tower with a small vestry, and a gallery. The vicarage house and garden are on a gradual slope on the south side of the churchyard. Traces of stonework show evidence of a prior church from the 12th century. It is a Grade I listed building.
There is no evidence of a church at Embleton preceding the Conquest. There are, however, some remains which indicate that there was a stone church on this site before the end of the 11th or in the early part of the 12th century consisting of a nave without aisles, a tower and a chancel. Of the tower, the lower portion remains. Light was provided by two windows, which are partly obscured.
The dedication to the Holy Trinity may have been preceded by another, as in Bacon's Liber Regis (1534–5) and in Randall's State of the Churches under the Archdeaconry of Northumberland (c. 1778), there is mention of a dedication to St. Mary. In 1830, when known as St. Mary's, the patron was Merton College, Oxford.
Embleton church's superstructure is similar to others such as those of Yorkshire or the Midlands. The open battlement resembles those found at Coxwold; this pierced battlement is an unusual feature for a country church in northern England.
Most of the Norman era nave no longer exists, except the walls which later included arcades. The subsequent nave has elements that are considered unusual for work done in the north country. It is 53 feet (16 m) long and 16 feet (4.9 m) wide, with two aisles. The chancel is 37 feet (11 m) in length and 18 feet (5.5 m) in width. The arcades have three bays each; their arches are supported by ornamented shafts. The arches have chamfered orders, and the hood-mouldings are also ornamented. In the north aisle, just above the eastern pillar, there is a square-moulded bracket which dates to the time of the aisle widening, about 1330-40; it was probably added to hold a light or image in connection with the adjoining chantry.
