Nicholas Snowden's mansion was built early in the 19th century on the present site of Pallotti High School. His daughter Louisa was the wife of Horace Capron, who was important in developing the Laurel Cotton Mill. The mansion was home for succeeding mill superintendents. From 1917 to 1957 it was a convent and school, St. Mildred's Academy. Just north of the Snowden-Capron Mansion, the 1840 Brick Assembly Hall was built by the mill as an auditorium. President Zachary Taylor was entertained there by Horace Capron.
