A
conference hall or
conference room is a
room provided for singular events such as
business conferences and
meetings. It is commonly found at large
hotels and
convention centers though many other establishments, including even hospitals, have one. Sometimes other rooms are modified for large conferences such as
arenas or
concert halls.
Aircraft have been fitted out with conference rooms. Conference rooms can be windowless for security purposes. An example of one such room is in the
Pentagon, known as the
Tank.
