who designed the tomb of the unknown soldier
Tomb of the Unknown Soldier (Arlington) Since 1921 the intent was to place a superstructure on top of the Tomb, but it was not until July 3, 1926, that Congress authorized the completion of the Tomb and the expenditure of $50,000 (with a completed cost of $48,000). A design competition was held and won by architect Lorimer Rich[nb 1] and sculptor Thomas Hudson Jones. An appropriation from Congress for the work was secured and on December 21, 1929, a contract for completion of the Tomb itself was entered into. The Tomb would consist of seven pieces of marble in four levels (cap, die, base and sub-base) of which the die is the largest block with the sculpting on all four sides.[4][7]
Tomb of the Unknowns While Arlington National Cemetery is open, during the day in summer months from April 1 to September 30, the guard is changed every half hour. During the winter months, from October 1 to March 31, the guard is changed every hour. After the cemetery closes to the public (7 p.m. to 8 a.m. April through September, and 5 p.m. to 8 a.m. October through March), the guard is changed every 2 hours. The ceremony can be witnessed by the public whenever Arlington National Cemetery is open.[20][21]
