Domformen

Domformen is a German term used in architectural history and related disciplines to describe the typology and morphology of domes, i.e., the shapes, construction methods, and symbolic meanings of domed ceilings. The word combines Dom (cathedral, dome) and Formen (forms). In scholarly contexts, Domformen covers a range of dome types, grouped by geometry, supporting structures, and cultural context.

Common dome forms include hemispherical domes (Kuppeln mit Halbkuppel); polygonal domes (polygonale Kuppeln); ribbed or modular domes; onion or bulbous domes (Zwiebelkuppeln); and modern geodesic or lattice domes used in contemporary architecture. Structural strategies to support domes are central to Domformen. Pendentives and squinches describe how a circular or polygonal dome is transitioned from a square or rectangular base to a circular plan. Different shell constructions (single-shell, double-shell) and materials (stone, brick, metal) influence form.

Historically, Domformen traces its development from ancient Roman and Byzantine rotundas to Renaissance and Baroque innovations, including Brunelleschi’s octagonal dome over Santa Maria del Fiore and later church domes. In the 19th and 20th centuries, innovations in engineering and new materials broadened possibilities, culminating in modern domes and geodesic designs.

In modern architectural scholarship, Domformen serves as a framework to analyze how domes convey spatial scale, weather protection, acoustics, liturgical function, and symbolic meaning. See also domes, pendentives, squinches.
