Conference hall

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. Typically, the facility provides furniture, overhead projectors, stage lighting, and sound system.

Sometimes the term 'conference hall' is used synonymously with 'conference center' as, for example, in 'Bandaranaike Memorial International Conference Hall'.

Typically a medium to large office or post-secondary educational facility has smaller meeting rooms often called a conference room or a huddle room. Possible setups
