The John Andrew and Sara Macumber Ice House is a historic building located on a farmstead southwest of Winterset, Iowa, United States.
 The Macumbers were natives of Gallia County, Ohio, and settled in Madison County in 1853.
 This building is a fine example of a vernacular limestone farm outbuilding.
 The single-story, one-room structure is composed of coursed rough cut stone on the main facade, and uncoursed rubble is used on the other elevations.
 It features quoins and jambs of roughly squared quarry faced stones on the main facade.
 There is a door on the south gable end, two metal ventilation pipes on the ridge of the roof, and no windows.
 Built sometime between 1875 and 1885, it is the only stone ice house known to exist in Madison County, and it is one of the few outbuildings built of stone.
 The ice house is located next to the garage, behind the house.
 It was listed on the National Register of Historic Places in 1993.
Laurel is a city in northern Prince George's County, Maryland, in the United States, located almost midway between Washington, D.C., and Baltimore on the banks of the Patuxent River.
 Founded as a mill town in the early 19th century, the arrival of the Baltimore & Ohio Railroad in 1835 expanded local industry and later enabled the city to become an early commuter town for Washington and Baltimore workers.
 Largely residential today, the city maintains a historic district centered on its Main Street, highlighting its industrial past.
The Ice House is a historic commercial building in Moulton, Alabama.
 It was built in 1946 at the beginning of Moulton's post-World War II boom period.
 After the town's previous ice house on the courthouse square was demolished to make way for new construction, R. W. Carter built a new ice house one block from the square with state-of-the-art ice making equipment.
 The ice house operated until 1977, serving homes and businesses in and around Moulton, as well as customers including Legion Field in Birmingham and the Browns Ferry Nuclear Power Plant across the Tennessee River.
 Today, the building houses an antique store, but the icemaking equipment is still intact.
 The building is a one-story, concrete block structure with a parapet roof.
 The façade has three original wood doors which originally enclosed the ice storage rooms, an entry door, and a window, all under a flat canopy.
 An office with two windows also projects from the façade.
 A concrete block residence constructed at the same time as the ice house sits behind the structure.
 The building was listed on the National Register of Historic Places in 2000.
The Forest City Velodrome is an indoor cycling facility in London, Ontario, Canada.
 The building was constructed in 1963 as the London Gardens, home to the London Knights ice hockey team.

 It was originally built in 1963 and was home to the London Knights ice hockey team from 1965 to 2002.
 The arena had a capacity of approximately 5,000 and was designed as a one level Boston Garden.
 The arena was originally named Treasure Island Gardens as the building was a part of the Treasure Island Plaza mall complex located in south London.
 The arena also included a second ice pad but was eventually closed.

The Cedar Falls Ice House is an historic structure located in Cedar Falls, Iowa, United States.
 It was built in 1921 and has been listed on the National Register of Historic Places since 1977.

Seminole Valley Farmstead is a collection of historic farm buildings located in Seminole Valley Park on the west side of Cedar Rapids, Iowa, United States.
 The historic designation includes the farm house (c. 1902-1903), summer kitchen, livestock barn, tool shed, ice house, chicken house, and smoke house.
 There is also a small orchard and a garden.
 The complex is located near a bend in the Cedar River.
 The farm represents a transitional period between Iowa's austere pioneer farms and the mechanized farms that developed later in the 20th century.
 The nearby timber was a source of raw materials for the farm, the fertile bottomland on which it is located provided rich soil for grazing and cultivation, and the smoke house and ice house were used to preserve agricultural products for later consumption.
 At the same time the barn and the chicken house were more substantial than those from earlier times.
 It was listed on the National Register of Historic Places in 1976.
The Potomac Curling Club is a curling club started in 1961 and currently curling in Laurel, Maryland.

 The club operates during the main curling season (October to April), although social events for the membership occur during the summer.
