The Watermill is built from red Norfolk brick over three storeys in six bays to the west elevation.
 Four of the six bays are recessed within giant enclosing arches.
 The arches are semicircular headed with raised ashlars and a Keystone.
 In the center of the west elevation of the mill there is a timber lucam (covered sack hoist) of shiplap construction.
 In front of the west elevation there is a bridge with a three centered arch through which the mill race flows.
 The bridge has a parapet wall.
 The rear east elevation is constructed with weatherboard cladding with a continuous first floor outshoot which houses machinery of the mill.
 Below this there are sluice gates beneath a three centered archway.
 The ground and first floor of the mill still contains the Mill wheel and the machinery all which are now listed.
 The surviving machinery includes a 13 ft wheel driving pit-wheel and wallower.
 There is a horizontal mainshaft that once drove 6 pairs of stones, although there are only five that now survive.The mill race still flows through under the building.
Goblintown Mill, also known as Turner's Mill, Wood's Mill, Walker's Mill, and Martin's Mill, is a historic grist mill complex located near Stuart, Patrick County, Virginia.
 The mill dates to the 1850s, and is a two-story, timber frame building on a dry stone foundation.
 The mill retains its original mill race and milling machinery.
 Associated with the mill is a 1 1/2-story, frame "storehouse" that housed a general store and dwelling.
 It was built about 1902.
Mill Race was a log flume ride that operated between 1963 and 1993 at the Cedar Point amusement park in Sandusky, Ohio.
 When it opened in 1963, Mill Race was only the second such log flume ride to ever operate in the world (the first being El Aserradero [The Sawmill] at Six Flags Over Texas, which had opened earlier that same year).
 Mill Race was ultimately removed from the park in 1993 to prepare for the opening of Raptor in 1994.
The Valley Falls Mill is an historic textile mill complex on Broad Street in Central Falls, Rhode Island.
 The complex consists of the primary mill building, a large Italianate brick four-story building erected in 1849, several outbuildings.
 a dam across the Blackstone River, and a portion of the original canal system which provided water power to the mill.
 The outbuildings include the gatehouse controlling waterflow into the canals, a small stuccoed office building now serving as a retail establishment, and a brick bath house built c. 1870 that stands just south of the mill race.
 The complex originally had a second mill building and power canal; that building was destroyed by fire, and its canal was filled in.
 The main mill building was developed as housing in the late 1970s, including a sympathetic replacement for the second mill building.
Raptor is a steel inverted roller coaster designed by Bolliger & Mabillard at Cedar Point in Sandusky, Ohio, United States.
 When built in 1994, it broke many records and held many firsts when it opened.
 Instead of having a short layout designed to fit into a compact area like , Raptor was designed with a larger, 3,790-foot (1,160 m) layout, making it the tallest, fastest and longest inverted roller coaster in the world when it opened.
 It features six inversions, including a cobra roll, a first for inverted roller coasters.
 At its opening, it was the largest investment in Cedar Point history.
 The ride is themed as a bird of prey.
The Amos Chase House and Mill are a historic property on New Hampshire Route 114, just south of the Piscataquog River in Weare, New Hampshire.
 The house is a 2-1/2 Greek Revival two-family house built c. 1836.
 It has two similar five-bay facades (southeast and northeast) with central entries framed by pilasters and topped by architraves.
 The adjacent mill building is also a wood-frame structure, built c. 1849.
 Both buildings have seen only modest and superficial alteration since their construction.
 The mill is the only surviving 19th-century mill building in Weare, out of a cottage industry that once saw a dozen or more such buildings.
 This mill was the only one in the town to survive the New England Hurricane of 1938, although its waterwheel was washed away.
 The mill race providing water to the mill from the Piscataquog is still visible on the property, as is a dam built by Chase.
 Chase was a tool manufacturer; his son later used the mill in the manufacture of baskets.
The Island Historic District is a mixed commercial and residential historic district located in Plainwell, Michigan.
 It is roughly bounded by Bannister Street to the north, Hill Street to the south, the Kalamazoo River to the east, and Park Street to the west, as well as including properties along Main Street south of the mill race and along Bridge Street west to the mill race.
 The district was listed on the National Register of Historic Places in 1991.
Trovinger Mill, also known as Rohrer's Mill, is a historic grist mill located in Hagerstown, Washington County, Maryland, United States.
 It was constructed in 1771 of roughly coursed local fieldstone.
 It is five bays in length with the mill race running underneath it about midway along its broad side.
 Nearby is the site of a newer mill, which is said to date later than the grain mill.
 Also present are the abutments of a bridge which crossed the Antietam at the mill as part of an 18th-century road leading from Hagerstown to the Old Forge about one and a half miles upstream.
 The structure contains much of the original woodwork as well as a significant part of the milling machinery.
Reed's Mill is a historic grist mill and national historic district located at Secondcreek, Monroe County, West Virginia.
 The district includes two contributing buildings and eight contributing structures.
 It was one of the original mill complexes of Secondcreek.
 The main mill building was built about 1791, and is a mortise and tenon frame structure held together with wooden pins, and sits atop a raised cut stone basement.
 A tall three-story section with basement was added in 1949.
