What is the definition of a balustrade?

1. A railing without any columns

2. A row of small columns topped by a rail

3. A solid wooden fence

4. A type of staircase

The correct answer is: A row of small columns topped by a rail

The definition of a balustrade is accurately captured by the choice that describes it as a row of small columns topped by a rail. In architectural terms, a balustrade serves both a functional and aesthetic purpose. Functionally, it acts as a protective barrier along the edges of stairs, balconies, and decks, ensuring safety by preventing falls. Aesthetically, balustrades enhance the visual appeal of structures, contributing to the overall design and style. The key components of a balustrade are the balusters, which are the individual small columns typically spaced evenly along the length of the railing. These are topped with a handrail, forming a complete protective structure. This definition emphasizes the combination of both the vertical elements (the balusters) and the horizontal element (the rail) which work together to form the balustrade, distinguishing it from simple railings or other structures.
