The Washington Monument is an obelisk on the National Mall in Washington, D.C., Constructed to commemorate George Washington, once commander-in-chief of the Continental Army (1775--1784) in the American Revolutionary War and the first President of the United States (1789--1797).
Located almost due east of the Reflecting Pool and the Lincoln Memorial, the monument, made of marble, granite, and bluestone gneiss, is both the world's tallest predominantly stone structure and the world's tallest obelisk, standing 554 ft 7 11?32 inches (169.046 m) tall according to the U.S. National Geodetic Survey (measured 2013--14) or 555 ft 5 1?8 inches (169.294 m) tall according to the National Park Service (measured 1884). It's the tallest monumental column in the world if all are measured above their pedestrian entrances. Overtaking the Cologne Cathedral, it was the tallest structure in the world between 1884 and 1889, and it had been overtaken by the Eiffel Tower in Paris. Construction of the monument began in 1848 and was stopped for a period of 23 years, from 1854 to 1877 because of a lack of capital, a battle for control within the Washington National Monument Society, and the American Civil War. Although the stone structure was completed in 1884, inner ironwork, the knoll, and installation of memorial stones weren't completed until 1888. A difference in shading of the marble, visible approximately 150 ft (46 m) or 27% up, shows where construction was halted and later resumed with marble from a different source. The original design was by Robert Mills (1781--1855) of South Carolina, but he did not include his proposed colonnade because of a lack of funds, proceeding only with a bare obelisk. The cornerstone was laid on July 4, 1848; the first stone was set atop the unfinished stump on August 7, 1880; the capstone was set on December 6, 1884; the completed monument was dedicated on February 21, 1885; and officially opened October 9, 1888. The Washington Monument is a hollow Egyptian style stone obelisk with a 500-foot (152.4 m) tall column surmounted by a 55-foot (16.8 m) tall pyramidion. Its walls are 15 feet (4.6 m) thick at its base and 1 1?2 ft (0.46 m) thick at their top. The marble pyramidion has thin walls only 7 inches (18 cm) thick supported by six arches, two between opposite walls which cross at the center of the pyramidion and four smaller corner arches.Ryugyong Hotel | |

The Ryugyong Hotel (Korean: ????; sometimes called Ryu-Gyong Hotel), or Yu-Kyung Hotel, is an unfinished 105-story, 330-metre-tall (1,080 ft) pyramid-shaped skyscraper in Pyongyang, North Korea. Its name ('funds of willows') is also one of the historic names for Pyongyang. The building is also known as the 105 Building, a reference to its number of floors. The building was planned as a mixed-use development, which would include a hotel. The building is currently listed by Guinness World Records as being the tallest unoccupied building in the world.Construction began in 1987 but was stopped in 1992 as North Korea entered a period of financial crisis after the dissolution of the Soviet Union. After 1992, the building stood topped out, but without any windows or interior fittings. In 2008, construction resumed, and the exterior was completed in 2011. It had been intended to open the hotel in 2012, the centenary of Kim Il-sung's birth. A partial opening was announced for 2013, but this was cancelled. In 2018, an LED screen was fitted to a side, which was used to show animation and movie scenes.
