_____ is a row of arches supporting a wall above and being supported by the piers.
🏛️ From a Single Arch to a Series
This question asks for the specific architectural term for a series of arches. While a single arch spans an opening, a row of arches creates a much larger and more complex structural and aesthetic element.
🧩 Identifying the Correct Architectural Term
(B) Arcade: A Row of Arches
An Arcade is the correct answer. It is defined as a succession or row of arches, each counter-thrusting the next, supported by columns or piers. Arcades are used to support a wall or roof, creating a covered but open-sided walkway below. They are a common feature in classical and medieval architecture, seen in everything from Roman aqueducts and the Colosseum to monastery cloisters and Renaissance loggias.
(A) Soffit: The Underside
A Soffit is the exposed undersurface of a single arch or lintel. It is a surface, not a series of structures.
(C) Crown: The Highest Point
The Crown is the highest point of the extrados (the outer curve) of a single arch. It is a specific location on one arch, not a row of them.
(D) Impost: The Supporting Block
An Impost is the block or molding at the very top of a pier or column on which the arch rests (at the springing line). It serves as the transition point between the vertical support and the curve of the arch. It is a component that supports an arch, not the row of arches itself.
🖼️ Famous Examples of Arcades
To better understand the concept, think of these famous structures:
- The Roman Colosseum: The exterior is famously composed of three stories of arcades, one on top of the other.
- Palace of the Doges, Venice: The ground floor features a beautiful arcade that creates a covered public walkway.
- Monastery Cloisters: The covered walkways surrounding the central courtyard of a monastery are almost always formed by an arcade.
In all these cases, the arcade provides strong support for the structure above while creating an open, sheltered space below.
