Following is the excerpt from the American Guide Series book,
Maine, a guide 'down east,' which relates to the monastery, which had opened as a monastery not long before the book was written. The monastery is number 30 on the book's list of points of interest in Portland.
30. The Mellen-Fessenden House (1807), now the Monastery of the
Precious Blood (public chapel), 166 State St., its former post-Colonial charm considerably altered, was built by Prentiss Mellen (1764-1840), statesman, U.S. Senator, and Chief Justice of Maine. In 1848, the house came into the possession of the Hon. William Pitt Fessenden (1806-69), lawyer, politician, and financier, godson of Daniel Webster and brother-in-law of Henry W. Longfellow. He served in the House of Representatives and Senate, and in 1864, was appointed Secretary of the Treasury by President Lincoln. Lincoln called him a radical without the petulant and vicious fretfulness of most radicals. In 1934 the house was made the cloister of the Catholic Monastery of the Precious Blood, and seven Sister Adorers entered the building at the time, not to emerge until death. An eighth has since joined them.
At one time cloistered in at least twelve monasteries, the Sisters Adorers of the Precious Blood are now housed in seven, this being one of the seven. The order was founded in 1861 by Catherine Aurelia Caouette in Saint-Hyacinthe, Quebec, Canada.
At one time their monasteries could be found from one end of the continent to the other, from Portland, Oregon in the west to Charlottetown, Prince Edward Island in the east.
This monastery, built in 1807 as a private residence, remained a private resident, passing through several hands, until being purchased by Bishop Louis S. Walsh of the Catholic Church in 1918. On January 6, 1919, the building was dedicated as a girls' school called King's Academy, remaining open until 1926, at which time the students were transferred to St. Joseph's Academy in Deering. In October of 1934, ownership of the property was transferred to the Sister Adorers of the Precious Blood, who remain there still.
Within is a chapel which one may visit daily while a local priest holds mass once a week.
