Clay Hall is a mid-twentieth century women’s dormitory located on the campus of Northern Oklahoma College in Enid, Oklahoma that has been listed on the National Register of Historic Places since 2012.
 Architect Roy W. Shaw designed it for Phillips University in 1941.
 The building was named after Robert Henry Clay, the husband of Sadie Clay, who had given a $25,000 donation to the project.
 A cornerstone ceremony was held on October 9, 1941.
 Mefford construction had completed the exterior by 1942, and the interior was completed in 1946, having been delayed by the onset of World War II.
 The dormitory cost $175,000 to build, and the University held a dedication ceremony on October 11, 1946.
 In 1951 and 1959, a north and a south wing were added to the building in order to accommodate an expanding student population.
 These additional wings increased Clay Hall's residential space from 150 women to 258, and its building size to 59,000 square feet.
 Phillips University's enrollment peaked in the 1970s, and the dormitory closed briefly in 1985, was reopened in 1986, and then permanently shut down in 1987.
 Clay Hall is the oldest dormitory on the campus.
 Its predecessor, Athenian Hall, was demolished in 1952, and a men's dormitory, Earl Butts Hall, was completed in 1955.

Bermuda Hundred was the first incorporated town in the English colony of Virginia.
 It was founded by Sir Thomas Dale in 1613, six years after Jamestown.
 At the southwestern edge of the confluence of the Appomattox and James Rivers opposite City Point, annexed to Hopewell, Virginia in 1923, Bermuda Hundred was a port town for many years.
 The terminology "Bermuda Hundred" also included a large area adjacent to the town.
 In the colonial era, "hundreds" were large developments of many acres, arising from the English term to define an area which would support one hundred homesteads.
 The port at the town of Bermuda Hundred was intended to serve other "hundreds" in addition to Bermuda Hundred.
The Preserve at Sharp Mountain (also called The Sharp Mountain Preserve) is a nature-based community located near Jasper, Georgia in Pickens County.
 It is one of three mountain communities in Pickens County, and the only one dedicated to maintaining its natural amenities.
 There are 12 mi of paved roads running through the community, but the population density is intentionally low (approximately 300 lots over 1600 acre ranging in size from a minimum of 3 acre to a maximum of 37 acres.)
 The Preserve at Sharp Mountain was named the "Best Community for Outdoor Lovers" by Pinnacle Living magazine, Unlike many planned communities, the Preserve at Sharp Mountain does not have swimming pools and tennis courts with club houses or golf courses.
 Instead, the Preserve at Sharp Mountain offers many acres of green space, hiking and nature trails, a nature pavilion, waterfalls, a bird sanctuary, a butterfly garden and various nature parks.
 The community is gated to restrict use of its 12 mi of privately owned roads to those living in the community.
 The Preserve at Sharp Mountain was developed by Four Seasons originally, which later became Naterra Land.
 Naterra's stated goal in all of its projects is "to better connect people with nature."
 Naterra Land sold out all of its inventory in the Preserve, and control of the community is now governed by a Property Owners' Association (POA).
 In 2011, the Preserve Association switched from being an HOA (Home Owners' Association) to being a POA (Property Owners' Association), each being viewed differently under Georgia law.
 In 2008 the Preserve became a recognized member of the national Firewise communities program and is one of the 13 in Georgia.

Elliott and Stoddard Halls are the two oldest remaining buildings on Miami University's Oxford Ohio campus today.
 Built in 1828 (Elliott) and 1835 (Stoddard), they were designed in the Federal style and modeled after Connecticut Hall at Yale University.
 They continue to be used as dormitory buildings, making them the two oldest college dormitories still in use in Ohio.
 They were the original dormitories on the campus and were built to house students who attended classes at Miami’s campus.
 They have both been through a number of renovations, most recently in 2011.
 The dorms are located in between the two academic quads located in the center of Miami's campus.
 They face another landmark on the campus, the Miami University seal.
 Over time they have become landmarks on the campus and are considered two of the most prestigious dorms to live in.
 They are also listed on the National Register of Historic Places.
 Currently they are the two oldest dormitory buildings in use today in the state of Ohio.
 Today, they house students in the Scholar Leaders program.
 The buildings are named for early Miami professors Charles Elliott and Orange Nash Stoddard.
