An arch is a curved structure that spans a space and may or may not support weight above it. Arch may be synonymous with vault but vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture and their systematic use started with the Ancient Romans who were the first to apply the technique to a wide range of structures.
An altar is any structure upon which offerings such as sacrifices are made for religious purposes, and by extension the 'Holy table' of post-reformation Anglican churches. Altars are usually found at shrines, and they can be located in temples, churches and other places of worship. Today they are used particularly in Christianity, Buddhism, Hinduism, Shinto, Taoism, as well as in Freemasonry. Also seen in Neopaganism and Ceremonial Magic. Judaism used such a structure until the destruction of the Second Temple. Many historical faiths also made use of them, including Greek and Norse religion.
In architecture, an atrium (plural: atria or atriums) is a large open space located within a building. Atria were a common feature in Ancient Roman dwellings, providing light and ventilation to the interior. Modern atria, as developed in the late 19th and 20th centuries, are often several stories high and having a glazed roof and/or large windows, and often located immediately beyond the main entrance doors (in the lobby). Atria are a popular design feature because they give their buildings a "feeling of space and light".[quote without source] The atrium has become a key feature of many buildings in recent years. Atria are popular with building users, building designers and building developers. Users like atria because they create a dynamic and stimulating interior that provides shelter from the external environment while maintaining a visual link with that environment. Designers enjoy the opportunity to create new types of spaces in buildings, and developers see atria as prestigious amenities that can increase commercial value and appeal. Fire control is an important aspect of contemporary atrium design due to criticism that poorly designed atria could allow fire to spread to a building's upper stories more quickly.
