Semi-domes

Definition

Semi-domes are architectural features that are half of a dome, typically positioned over an entrance or on the sides of a central dome. They are integral in the design of religious buildings, providing both structural support and aesthetic appeal, particularly in large-scale structures like churches. These elements help to transition between different architectural forms, allowing for a more complex spatial arrangement within a building.
