1. Century Plaza Hotel, Los Angeles, California
Designed by Minoru Yamasaki, the architect who later designed the Twin Towers in New York City, this bow-shaped hotel opened in Los Angeles in 1966. The Century Plaza Hotel is in excellent condition after undergoing $36 million in renovations. According to the National Trust, the energy represented in the Century Plaza equals 167,000 barrels of oil. Those resources could be totally wasted if this landmark is razed by its new owners, who plan to replace it with two “environmentally sensitive” towers.
2. Miami Marine Stadium, Miami, Florida
Miami Marine Stadium, a landmark in southern Florida, has been an object of desire for many developers since 1992 when it closed due to damage from Hurricane Andrew. Over the past 17 years, Miami Marine Stadium has deteriorated due to vandalism and neglect. Completed in 1963, the 6,566-seat stadium, which was designed by Hilario Candela and built entirely of concrete, is an icon of modern design.

Located in southeastern Massachusetts, the Ames Shovel Shops compound is a 19th century industrial village. The site is an important piece of America’s industrial history; the iron shovels produced there were fundamental in events such as the California Gold Rush, the Civil War, and the building of the Transatlantic Railroad. Numerous buildings in the historic village are now threatened by development plans to build a new affordable housing complex on site.
7. Memorial Bridge, Portsmouth, New Hampshire and Kittery, Maine
Spanning the Piscataqua River, Memorial Bridge was the first major vertical lift bridge built in the eastern United States. Connecting the two coastal towns of Kittery, Maine and Portsmouth, New Hampshire, its twin towers and wood-floored pedestrian walkway has been a national landmark for more than 85 years. However, deterioration from postponed maintenance and budget issues has endangered Memorial Bridge and may result in its removal.
8. Mount Taylor, Grants, New Mexico
Visible from 100 miles away, Mount Taylor’s beautiful 12,000-foot peak is a sacred pilgrimage destination for over 30 Native American tribes. Mount Taylor was originally named by the Acoma people as Kaweshtima, or “place of snow.” Mount Taylor is a significant part of Acoma culture and a National Trust Historic Site, and sits on top of large uranium reserves. Today, potential mining exploration threatens its future existence and by extension, the survival of the Acoma people.

An important collection of buildings in the history South Dakota, the Human Services Center in Yankton, is the oldest public institution in the state. Originally a hospital for the insane, it was built by Dr. Leonard Mead.

Today, the 11 historic buildings that comprise the campus are uninhabited and in danger of being demolished by the state.
10. Cast-Iron Architecture of Galveston, Texas
In Sept. 2008, the town of Galveston, Texas was hit by Hurricane Ike and the ensuing floods caused extensive damage to its cast-iron architecture. The town’s 12-block center is one of the country’s largest collections of historic commercial buildings in the country and a National Historic Landmark District. The buildings and storefronts were constructed in the late 19th century with elaborate Greek revival and Italianate designs. The water from Hurricane Ike destroyed many of the buildings, however, and without flood insurance many storeowners cannot complete necessary repairs.
11. The Manhattan Project’s Enola Gay Hangar, Utah
Located 100 miles west of Salt Lake City, the Wendover Air Force Base played an important part in the Manhattan Project. The Wendover hangar was once home to the Enola Gay, the B-29 airplane that carried the first atomic bomb to Hiroshima, Japan. Although the Enola Gay was fully restored for the National Air and Space Museum, the Wendover hangar suffered severe deterioration after the Air Force base closed in 1969.
