The All Hallows Guild Carousel, or simply the Traveling Carousel, is a historic carousel housed at the National Cathedral in Washington, D.C. since 1963. Previously, it operated as a "county fair" carousel under Clifford Sandretzky as part of a traveling carnival based in the northern Virginia area. The carousel, constructed primarily of wood, is a rare piece believed to have been built by the Merry-Go-Round Company of Cincinnati in the 1890s. It features a unique caliola with brass pipes that was built by the Rudolph Wurlitzer Company of North Tonawanda, New York in 1937.

Number One Observatory Circle, often referred to as the Naval Observatory, is the official residence of the vice president of the United States. Located on the northeast grounds of the U.S. Naval Observatory in Washington, D.C., the house was built in 1893 for the observatory superintendent. The chief of naval operations (CNO) liked the house so much that in 1923 he took over the house for himself. It remained the residence of the CNO until 1974, when Congress determined that it would be easier and less expensive to provide security in a government-provided residence, and authorized its transformation to the first official residence for the vice president, though a temporary one. It is still the "official temporary residence of the vice president of the United States" by law. The 1974 congressional authorization covered the cost of refurbishment and furnishing the house.
