Mount Saint Bernard Seminary and Barn are historic buildings located south of Dubuque, Iowa, United States.

[2] The Brothers of Christian Instruction, a French teaching order recruited to the diocese of Loras, contributed their services to the seminary.

[3] The school was expanded in 1850 when he began the construction of three new buildings on Table Mound that he named Mount St. Bernard College and Seminary.

Andrew Trevis, who was later influential in the development of Sacred Heart Cathedral in Davenport, was the rector at the time the building was constructed.

A number of factors conspired to close Mount Saint Bernard, including economic conditions and a lack of clergy.
