Most Holy Trinity Church

Most Holy Trinity Church is a stone building that has stood on Boston Post Road since 1886, featuring high ceilings and large windows that fill the interior with light. The structure displays traditional architectural elements from that era and functions as a place for worship and community gathering.

The first Catholic community in Mamaroneck began with a priest traveling monthly by wagon from New Rochelle to conduct services in homes of the faithful. The stone building that stands today was constructed later as the parish grew and needed a permanent place to worship.

The church serves as a gathering place where the local community comes together for prayer and religious observance throughout the year. The stone building itself expresses the faith and dedication of those who built and maintained it over generations.

The church is open for individual prayer and hosts religious services several times each year for the parish community. Visitors should check ahead for service times and observe respectful behavior when ceremonies are taking place.

The building faced closure in 2018, but parishioners successfully appealed to the Vatican and prevented the permanent shutdown of this historical church. This unexpected reversal shows the power of local advocacy for preserving religious sites with deep community roots.
