The first pipe organs were built in the 3rd century BC in Greece. These early organs were very simple, with only a few pipes. Over time, organs became more complex, and they began to be used in churches and cathedrals. By the 16th century, organs were some of the most complex and sophisticated instruments in the world.
Today, pipe organs are still used in churches and cathedrals, as well as concert halls and other venues. They are considered to be one of the most beautiful and majestic instruments in the world.
