    drawings & plans 
    This drawing of the White House groin vaulting was done by artist Dahl Taylor. The groin vaulting and a support system of arches was originally constructed in the old basement of the Executive Mansion by stonemasons under the supervision of Collen Williamson and Jeremiah Kale. The original vaulting survived until the Harry S. Truman renovation from 1948-1952.
