A country house in Sussex designed by this architect was owned by Led Zeppelin from 1973 to 1982 and was called Hammerwood Park.  This man created a panopticon-inspired semicircular three-story design for the Virginia State Penitentiary. This man is often credited with introducing the Greek Revival style to the United States with his the Bank of Pennsylvania. John Carroll commissioned this man to design the first Roman Catholic Cathedral in the United States, which is located in Baltimore.  In this artist's most famous assignment, he constructed the South Wing and rebuilt the North Wing, but he resented using the plans of William Thornton for that building, and he was succeeded as architect of that building by Charles Bulfinch.
