St. Mark's Episcopal Church of Warren is the first parish in the Diocese of Rhode Island to bear the name St. Mark and is the 7th oldest Episcopal parish in the State of Rhode Island.

St. Mark's Church was begun on November 10, 1828, by 17 individuals who wished to organize a church following the Episcopal tradition in Warren.  Their early services were held at Cole's Tavern in Warren.   In 1829 the group was strong enough to initiate the construction of a building for worship on their own.  They wanted a beautiful church, for the sum of $4,000 they were able to contract one of the most prominent architects of the times, Dr. Russell Warren, who built the Arcade (the first indoor shopping mall) and the old brick Railroad Station in Providence.  In 1830 the church was completed.  St. Mark's Episcopal Church is currently the oldest standing church building in the Town of Warren.  A year later they installed the first Church organ ever heard in Warren for the cost of $650  The Rev. George W. Hathaway was chosen as the first rector.  He ministered to the flock for 21 years, under his guidance St. Mark's became a firmly established church.

In 1852 a chapel was built, to house the Sunday School which up until then had been meeting in the basement of the church, at a cost of $1200.  The chapel stood in the rear of the church lot at right angles to but not connected to the church, with it's front on School Street.

In 1855 a fire extensively damaged the nave of the church and the design was somewhat altered in its restoration.

In 1858, the lot across School Street was purchased for the sum of $400, and the Chapel was moved to it's present location.  In 1860 an addition was added and the building name changed to parish hall. 

A hurricane on Sept 21, 1938 damaged church.  After the storm three trees were resting on roof causing so much damage the entire roof had to be replaced.

Another hurricane in 1945 weakened the bell tower of the church and it had to be removed.  The bell now stands in the church yard.
