Holy Trinity Chapel was built in 1901 on land donated by the Canadian Atlantic Railway. In 1942, the whole village of Madawaska was forced to move when the dam on Bark Lake was erected and the townsite was flooded. The chapel building was moved to the new village and rededicated on January 31, 1943 by the priest and the Rural Dean.
Today Holy Trinity Madawaska is one of three chapels in the Parish of the Valley. A service of worship is held once per year, and the chapel is also available at all times for baptisms, weddings and funerals. Holy Trinity chapel is sponsored by the congregation of St. Anthony's Whitney. The chapel stands in the middle of town with its well-kept and well-used cemetery, reminding passers-by of over a century of Anglican ministry.
