"fan vault" の定義と意味

What is a "fan vault"?

A fan vault is an intricate architectural feature characterized by a series of curved, spreading ribs that resemble the shape of a fan. This type of vault creates a visually striking ceiling, often seen in the interiors of Gothic churches and cathedrals. The ribs extend from a central point, spreading outwards to form a series of inward-curving surfaces that are often elaborately decorated. Fan vaults not only enhance the aesthetic appeal of a space but also provide structural support, allowing for the construction of grand and open interiors. Their unique design adds a sense of elegance and complexity to Gothic architecture.
