The Emperor's Palace in Milan was founded in about 291 AD by emperor Diocletian. Here Constantine and Licinius issued the Edict of Milan in 313 AD.
Residential and ambassadorial sectors, private baths and the circus, where the Emperor appeared solemnly to his subjects, and victory in chariot races became symbolic of Imperial victories, took up an entire sector of the city. The only visible traces of this vast polyfunctional quarter, which stayed in use perhaps up until the tenth century, are the remains of an ambassadorial building which had central heating; many archaeological remains are probably to be found under the buildings around Via Brisa.
Arlington National Cemetery is one of the most famous cemeteries in the world. The United States military cemetery was established during the Civil War on the grounds of Arlington House, which had been the estate of the family of Confederate general Robert E. Lee"s wife Mary Anna Lee. On June 15, 1864, the Arlington House property and 200 acres of surrounding land were designated as a military cemetery as Quartermaster General Montgomery C. Meigs wanted to ensure that Lee could not return to the site.
Today the cemetery is the final resting place for more than 300,000 veterans died in every American conflict, from the Revolutionary War to Iraq and Afghanistan.
The first soldier to be buried in Arlington was Private William Henry Christman of Pennsylvania on May 13, 1864. The most famous people buried to Arlington are Presidents William Howard Taft and John F. Kennedy. Also Kennedy"s two brothers, Senator Robert F. Kennedy and Senator Edward 'Ted' Kennedy, and General of the Armies John J. Pershing are buried there.
