See if it's possible to attend a worship service at The Synagogue. You'll learn about some of the traditions and practices of the Jewish faith.
The Synagogue has an admission fee and is a popular attraction in Old Town. There are plenty of other things to do and see close by, so why not stick around a while longer? Modena Cathedral, Torre della Ghirlandina and Museo Enzo Ferrari are also on the itineraries of many travelers.
