It is not known exactly when the Tiefburg castle was built or by whom. It is assumed that it was built in the 12th century, possibly by the Abbey of Lorsch or the Count Palatinates of the Rhine (later known as the Prince Electors of the Palatinate), who set up residence in nearby Heidelberg around this time. It is also possible that the castle had its origins in a fortiied estate. The knights of Handschuhsheim who lived in the Tiefburg were initially unfree knights, known as ministeriales, in the service of the Abbey of Lorsch, and later on vassals of the Prince Electors of the Palatinate. The dynasty died out when the last knight of Handschuhsheim, Johannes (Hans) V., died aged 16 on 31st December 1600 from injuries sustained in a duel. Through inheritance, the Tiefburg became the property of the barons of Helmstatt (who became counts of Helmstatt in the 18th century).
Tiefburg was badly damaged in the Thirty Years‘ War. In 1689 it fell victim to the War of the Palatine Succession and became uninhabitable, whereupon the Helmstatts built a new residence in the immediate vicinity. The original gate of this new residence can still be seen to the east of the square in front of the Tiefburg. Count Raban von Helmstatt had the Tiefburg restored in the years 1910 to 1913.References:
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.
