Our Lady Help of Christians Historic District encompasses a complex of Roman Catholic religious buildings in the Nonantum village of Newton, Massachusetts.

It includes four fine examples of brick Gothic Revival architecture: the church, convent, and rectory, as well as Trinity Catholic High School.

[1] Our Lady Help of Christians is located on a large parcel at the northwest corner of Washington and Adams Streets, just north of the Massachusetts Turnpike.

The church was designed by Providence-based ecclesiastical architect James Murphy, and construction took two years (1873–75), hampered by funding difficulties and the death in a fall of its principal brickworker.

Due to defects in the construction, the building underwent a major renovation in 1900 that added further supports to the walls, as well as the facade with three Gothic porches.
