After many years of renovations, this site is finally accessible again. I first went to Modena in April 2011, only to find the cathedral and the bell tower completely covered in scaffolding - 6 months after the original due date that was still posted on the site. A second visit in October 2013 finally enabled me to see more than just the piazza (a nice one with an impressive Town Hall, but nothing outstanding - not sure why it is specifically mentioned in the WH name). The bell tower is completely renovated and also fully accessible - I did the climb up to the top to enjoy a nice view of the city. Except for a small part of the façade, the cathedral is also fully renovated and can be visited again. I went inside only briefly, as there was a Mass going on, but I'm still glad that I could finally tick off this site. Modena is easily accessible from Bologna and Milan, and the train station is quite close to the city centre. It's not a city where I would spend more than a day, though.
