Organs can tell you more about the history of the city or the village. Especially old organs have interesting decorations. You will see carvings, statues and decorations. You can often read the names and dates of the organ builder and sometimes also of the people who paid for the organ. Over time, an old organ has sometimes been expanded with new stops. Each part tells something about how the organ was used in different times. For congregational singing or for concerts. Or as a precious jewel to impress visitors with.
