The Bell Caves have a unique sound. What makes the Bell Caves unusual and worth a visit is the acoustic effect created by the connections between the chambers. As the sound moves between the large chambers along the passageways, a very distinctive reverberance is heard, as sound sloshes about from one chamber to another.
The caves were quarries which were excavated at different times in history, but it is claimed some date back to the 4th century B.C. The walls are made of beige coloured limestone.
The Bell Caves are in the Beit Guvrin National Park. The park also contains a Roman amphitheatre.
