A postcard view of St. Mary's Church, Biddeford, around 1909. St. Mary's was one of three large Catholic churches in Biddeford during this time. It catered primarily to the Irish Catholic population.

The church buildings lined the street, and included the rectory, a convent, and a school. This building was eventually demolished and a new, larger church constructed to replace it in the 1920's. The school and convent have since been demolished, and the church and rectory closed in 2009.

This postcard was sent on March 12, 1909 to Mrs. William Gleed of Newton, New Hampshire. It reads: "Dear Mrs. Gleed, I found my sister well and baby quite smart. Having a pleasant time. Lovingly, Alice F."
