What is a tholos in terms of architectural structure?

A tholos is defined as a circular building that typically features a dome or a vaulted roof. This architectural form was prominent in ancient Greece, particularly during the Mycenaean period, and is characterized by its unique circular plan. The structure often served significant cultural and ceremonial purposes, such as housing important gatherings, rituals, or offerings.

The design of a tholos allows for a central space that can be used for various activities, making it not only distinct in its shape but also functional. The use of domes or vaulted ceilings in these constructions also demonstrates advanced engineering techniques of the time, showcasing the significance of aesthetics as well as structural integrity in ancient architecture.

This understanding of the tholos highlights its importance in the development of architectural forms and the cultural practices of the societies that employed such designs.
