Historic American landmark, Washington National Cathedral, the church used for Presidential inauguration services and Presidential funerals since the 1800s, will now perform same-sex weddings. The decision, made by the Episcopal denomination in Washington D.C, reflects the alarming trend of churches that have abandoned Biblical Christianity in favor of person-made doctrines, even if they go against the Word of God. This falling away from sound Christian doctrine, called the Apostasy in the Bible, was prophesied to occur as the end times approached.

I learned that he could read in over six languages. He loved Italy the architecture and the art. He was the ambassador of the United States in France.

The National Museum of Natural History is part of the Smithsonian Institution, the world’s preeminent museum and research complex. The Museum is dedicated to inspiring curiosity, discovery, and learning about the natural world throughout its unparalleled research, collections, exhibitions, and education outreach programs. Opened in 1910, the green-domed museum on the National Mall was among the first Smithsonian building constructed exclusively to house the national collections and research facilities.
Whether looking at the history and cultures of Africa, describing our earliest Mammalian ancestor or primate diversity around the world, examining ancient life forms including the ever popular dinosaurs, or exploring the beauty of rare gemstones such as uniquely colored diamonds, the Museum’s temporary and permanent exhibitions serve to educate, enlighten and entertain millions of visitors each year. The main building on the National Mall contains 1.5 million square feet of space overall and 325,000 square feet of exhibition and public space; altogether the Museum is the size of 18 football fields, and houses over 1,000 employees.

Many of the materials, decorations, and furnishings throughout the building are donations from more than 40 countries.

The National Zoological Park is a part of the Smithsonian Institution, the world’s largest museum and research complex. The Smithsonian includes 18 museums and galleries, as well as the National Zoo.

The Steven F. Udvar-Hazy Center near Washington Dulles International Airport is the companion facility to the Museum on the National Mall.

The Lincoln Memorial, an iconic landmark on the National Mall in Washington, DC, is a tribute to President Abraham Lincoln, who fought to preserve our nation during the Civil War, from 1861-1865. The Memorial has been the site of many famous speeches and events since its dedication in 1922, most notably Dr. Martin Luther King, Jr.’s “I Have a Dream” speech in 1963.

A beautiful structure with seven-foot diameter columns that stretch 44 feet high, architect Henry Bacon designed the Lincoln Memorial in a style similar to a Greek temple. The structure’s 36 columns represent the 36 states in the Union at the time of Lincoln’s death. A 19-foot larger than life-size marble statue of Lincoln sits in the center of the memorial and the words of the Gettysburg Address and the Second Inaugural Address are inscribed on the walls. The Memorial is often less crowded at night and is most impressive when it is illuminated.

One of the oldest tourist attractions in Washington DC is the Washington Monument. Located on National Mall adjacent to Lincoln Memorial, this monument is tribute to one of the greatest legends of America, George Washington. George Washington was the first president of United States and one of the main founders of country. He is described as a great and honorable man in history and therefore it only made sense to honor him in some way after his death and that’s why Washington Monument was constructed in heart of the capital. On Washington’s 100th birthday people started fundraising and collecting donations to build a monument to honor him. Competitions were organized to choose the best design for the monument. The design chosen resembled the Egyptian obelisk. There were several delays in the construction and that’s why same stone could not be used. The stone changes its color from the bottom third of the monument. The materials used were sandstone, marble and granite and the tip was made from cast aluminum which at that time was even more expensive than silver. The construction of the Washington Monument for the first president was completed by Army Corps of Engineers in 1884. The monument is over 555’ in height which makes it the tallest obelisk in the world.

The world's largest museum complex, the Smithsonian Institution houses an impressive medical sciences collection. It dates from 1876, when about 600 crude drug specimens, displayed at the Centennial Exhibition in Philadelphia, were deposited in the U.S. National Museum.

The White House is a grand mansion in the neo-classical Federal style, with details that echo classical Greek Ionic architecture. James Hoban's original design was modeled after the Leinster House in Dublin, Ireland and did not include the north and south porticos. The presidential mansion is situated on the angled Pennsylvania Avenue at the 1600 block, down the street from the Capitol building, and so is given the address 1600 Pennsylvania Avenue NW, Washington, DC.
