Often, you can reach the cupola by climbing a stairway inside the building. This type of cupola is called a belvedere or a widow's walk. Some cupolas, called lanterns, have small windows which illuminate the areas below.

What is a balustrade? A balustrade is a row of repeating balusters -- small posts which support the upper rail of a railing. Staircases and porches often have balustrades.What is a mansard roof?

A mansard roof has two slopes on each of the four sides. The lower slope is steeper than the upper slope. Dormers are often set in the lower slope. The upper slope is usually not visible from the ground.

Illustration from ArtToday.comThe term "mansard" comes from the French architect Franois Mansart (1598-1666) of the Beaux Arts School of Architecture in Paris, France. Mansart revived interest in this roofing style, which had been characteristic of French Renaissance architecture, and was used for portions of the Louvre. Another revival of the mansard roof occurred in the 1850s, when Paris was rebuilt by Napoleon III. The style became associated with this era, and the term Second Empire is often used to describe any building with a mansard roof. Mansard roofs were considered especially practical because they allowed usable living quarters to be placed in the attic. For this reason, older buildings were often remodeled with mansard roofs. In the United States, Second Empire -- or Mansard -- was a Victorian style, popular from the 1860s through the 1880s.What is a battlement?What is a crenellation?What are embrasures?What are merlons?On a castle or fort, a battlement or a crenellation is a parapet with open spaces for shooting. The raised portions of a battlement are called merlons, and the openings are called embrasures. Masonry buildings in the Gothic Revival style may have architectural decoration which resembles battlements.What is a parapet? A parapet is a low wall projecting from the edge of a platform, terrace, or roof. Parapets may rise above the cornice of a building or form the upper portion of a defensive wall on a castle. In Mission style homes, rounded parapets are often used as decorative features.What is a quatrefoil window? A quatrefoil window is a round window which is composed of four equal lobes, like a four-petaled flower. The quatrefoil pattern is common in Moorish and gothic architecture. Also, many Mission style homes have quatrefoil windows.

What is an oriel window?An oriel window projects from the wall and does not extend to the ground. Oriel windows originated as a form of porch. They are often supported by brackets or corbels. Buildings in the Gothic Revival style often have oriel windows.

A column is an upright pillar or post. Columns may support a roof or a beam, or they may be purely decorative. The lower portion of a column is called the base. The upper portion of a column is called the capital. The area which the column supports is called the entablature. Classical columns are built according to the Classic Orders of Architecture as recorded in the late 1500's by the Renaissance architect, Vignola. The classical column designs are:

A combined style, known as Composite, was developed in Ancient Rome.What is stucco? Traditional stucco is a cement mixture used for siding, usually on Mission or other Spanish style homes. The cement is combined with water and inert materials such as sand and lime. Usually, wooden walls are covered with tar paper and chicken wire or galvanized metal screening. This framework is then covered with the stucco mixture. Sometimes, the cement mix is applied directly to specially prepared masonry surfaces.This Spanish style home in Miami Springs, Florida has stucco siding. The homeowner, Kim, sent this photo for our Mystery House series, where you can see more views of the house.Although stucco-sided homes became popular in twentieth century America, the concept of using cement mixtures in architecture goes back to ancient times. Wall frescoes by ancient Greeks and Romans were painted on fine-grained hard plaster surfaces made of gypsum, marble dust and glue. Stucco techniques were elaborated by the Italians during the Renaissance and spread through Europe. This marble dust compound could be molded into decorative shapes, polished to a sheen or painted. Many homes built after the 1950s use a variety of synthetic materials which resemble stucco. Mock stucco siding is often composed of foam insulation board or cement panels secured to the walls. Although synthetic stucco may look authentic, real stucco tends to be heavier. Walls made of genuine stucco sound solid when tapped and will be less likely to suffer damage from a hard blow. Also, genuine stucco holds up well in wet conditions. Although it is porous and will absorb moisture, it will dry easily, without damage to the structure. One type of sythetic stucco, known as EIFS (Exterior Insulation and Finish Systems), has been associated with moisure problems. The underlying wood on EIFS sided homes may suffer rot damage. However, other types of synthetic stucco are quite durable. It's always a wise to have a professional inspection before purchasing a stucco-sided home.For more information about stucco problems, see EIFS Central from your Guide to Home Repair.

The spaces between the wooden timbers are filled with plaster, brick, or stone.Illustration from ArtToday In Medieval times, many European houses were half-timbered. The structural timbers were exposed. In the United States, harsh winters made half-timbered construction impractical. The plaster and masonry filling between the timbers could not keep out cold drafts. Builders began to cover exterior walls with wood or masonry.

In the 19th and 20th centuries, it became fashionable to imitate Medieval building techniques. Many Queen Anne and Stick style houses were given false half-timbering. Timbers were applied to wall surfaces as decoration. Tudor, or Medieval Revival, style houses were often lavishly covered with ornamental half-timbering.

What is a "chimney pot"?

Tudor or Medieval Revival style buildings often have wide, very tall chimneys with round or octagonal "pots" on top of each flue. Multiple chimneys have separate flues, and each flue has its own chimney pot. Some chimney pots are beautifully decorated, like the ones shown here.

What is Beaux Arts?

Pronunciation: bO-zr'; or bO-zar' in FrenchIn French, the term beaux arts means fine arts. Based on ideas taught at the legendary cole des Beaux-Arts in Paris, the Beaux Arts style flourished between 1885 and 1920. Combining ancient Greek and Roman forms with Renaissance ideas, Beaux Arts is an eclectic Neoclassical style. Colossal masonry buildings are highly ornamented with garlands, flowers or shields. Often you'll find a profusion of columns, pilasters, balustrades and window balconies. Because of the size and grandiosity of these buildings, Beaux Arts became the favored style for court houses, museums, railroad terminals and government buildings. The Beaux Arts movement was also concerned with formal design and city planning. In the United States, these ideas inspired planned suburbs with vast parks and wide, manicured boulevards lined with large, showy houses. Beaux Arts architecture fell out of favor by the mid-20th century. The massive, elaborate buildings were considered ostentatious. Frank Lloyd Wright called them "Frenchite pastry" (In the Course of Architecture). However, later in the 20th century some postmodernist theorists awakened a new appreciation for Beaux Arts ideas.What is a bargeboard?What is a vergeboard? Bargeboards -- also called vergeboards -- hang from the projecting end of a roof. Bargeboards are often elaborately carved and ornamented. Homes in the Carpenter Gothic style have highly ornamented bargeboards. Other common terms to describe bargeboards and vergeboards include: fly rafters, gable rafters, gableboards and barge rafters.

A buttress is a support -- usually brick or stone -- built against a wall to support or reinforce it. A flying buttress is a free-standing buttress attached to the main structure by an arch or a half-arch.

Flying ButtressIllustration from ArtToday.comCob Houses

In Old English, cob was a root word which meant lump or rounded mass. Cob houses are made of clay-like lumps of soil, sand and straw. Unlike adobe and straw bale construction, cob does not use bricks or blocks. Instead, wall surfaces can be sculpted into smooth, sinuous forms. A cob home may have sloping walls, arches and lots of wall niches. Cob homes are possibly the most practical form of earth architecture. Because the mud mixture is porous, it withstands long periods of rain without weakening. A plaster made of lime and sand may be used to windproof the exterior walls from wind damage. Cob houses are suitable for the desert or for very cold climates.What is a dentil molding? A dentil is one of a series of a series of closely spaced, rectangular blocks that form a molding. The dentil molding usually projects below the cornice, along the roofline of a building. However, the dentil molding can form a decorative band anywhere on the structure.

The center section is larger than the two side sections, and is usually arched. Renaissance architecture and other buildings in classical styles often have Palladian windows. On Adam or Federal style houses, there is often a Palladian window in the center of the second story.The term "Palladian" comes from Andrea Palladio, a Renaissance architect whose work inspired some of the greatest buildings in Europe and the United States. Modeled after classical Greek and Roman forms, Palladio's buildings often featured arched openings. Shown here is a detail drawing of arched windows in Andrea Palladio's basilica.
