Visit Arlington National Cemetary

Arlington National Cemetery is part of a tract of land with a history of ownership dating to 1669. In that year the royal governor of Virginia, Sir William Berkeley, awarded a grant of 6,000 acres to Captain Robert Howsing in recognition of Howsing's bringing settlers from England to the colony aboard his ship. Howsing apparently preferred the life of a seaman to that of landowner, however, and sold the tract to John Alexander in exchange for six hogsheads of tobacco.
In 1778, the 1,100 acre tract which today contains the Fort Meyer Military Reservation and Arlington Cemetery was purchased by John Parke Custis who was Martha Washington's son by her first husband, Daniel Parke Custis. John Custis was an aide-de-camp to General George Washington and died in the battle of Yorktown in 1781. Two of his four children, George Washington Parke Custis and Eleanor Parke Custis, were adopted by George and Martha Washington following his death. It was young George who brought the name "Arlington" to the property.
George Custis inherited Martha Washington's property upon her death in 1802 and came into possession of his step-grandfather's memorabilia. In 1804, he built a Greek Revival-style house on the Custis estate overlooking the Potomac River to store the memorabilia and named it Arlington House; "Arlington" comes from the name of the original Custis estate on the Virginia coast, granted to the family by the Earl of Arlington.
Two of the leading families of this nation's history were linked by Mary Ann Randolph Custis, daughter of George Washington Parke Custis and Mary Fitzhugh. In 1831, Mary Custis married Lieutenant Robert E. Lee thus joining the Washington and Lee families as well as setting the stage for the appropriation of land which once belonged to George Washington (through marriage) for use as a national burial ground.

For two hundred years, the White House has stood as a symbol of the Presidency, the United States government, and the American people. Its history, and the history of the nation’s capital, began when President George Washington signed an Act of Congress in December of 1790 declaring that the federal government would reside in a district "not exceeding ten miles square…on the river Potomac." President Washington, together with city planner Pierre L’Enfant, chose the site for the new residence, which is now 1600 Pennsylvania Avenue. As preparations began for the new federal city, a competition was held to find a builder of the "President’s House." Nine proposals were submitted, and Irish-born architect James Hoban won a gold medal for his practical and handsome design.

The National Aquarium in Baltimore seeks to stimulate interest in, develop knowledge about, and inspire stewardship of aquatic environments.

Exhibits are designed to replicate natural environments and avoid the unnatural mixing of species. Specimens are chosen to give the best examples of biological concepts in an interesting and accurate way. The collections embrace diverse world-wide habitats.

The ultimate goal is for the exhibits and programs to spark

The United States Capitol is among the most symbolically important and architecturally impressive buildings in the nation. It has housed the meeting chambers of the House of Representatives and the Senate for two centuries. The Capitol, which was started in 1793, has been through many construction phases. It stands today as a monument to the American people and their government.

 Visit the Holocaust Museum

The Holocaust was the systematic, bureaucratic, state-sponsored persecution and murder of approximately six million Jews by the Nazi regime and its collaborators. "Holocaust" is a word of Greek origin meaning "sacrifice by fire." The Nazis, who came to power in Germany in January 1933, believed that Germans were "racially superior" and that the Jews, deemed "inferior," were "life unworthy of life." During the era of the Holocaust, the Nazis also targeted other groups because of their perceived "racial inferiority": Roma (Gypsies), the handicapped, and some of the Slavic peoples ( Poles , Russians, and others).

The Museum's Permanent Exhibition The Holocaust spans three floors of the Museum building. It presents a narrative history using more than 900 artifacts, 70 video monitors, and four theaters that include historic film footage and eyewitness testimonies. The exhibition is divided into three parts: "Nazi Assault," "Final Solution," and "Last Chapter." The narrative begins with images of death and destruction as witnessed by American soldiers during the liberation of Nazi concentration camps in 1945. Most first-time visitors spend an average of two to three hours in this self-guided exhibition. Recommended for visitors 11 years of age and older.
