As of August 2023 when we visited you were able to book a free 15 minute time slot on their rooftop…read moreviewing terrace which I highly recommend. Know that you will need to book about 3 weeks in advance, because it seems like all the spots go pretty quickly so you much plan ahead! But it is worth it because it is a cool place!
The rooftop viewing terrace is definitely worth it, what a great view of the entirety of Venice, including the Rialto Bridge which you can see well from the top. The time slots are kind of nice as it limits the number of people out there, giving enough room for getting pictures and enjoying the view.
The department store itself is also really cool. An awesome space, the big central indoor area was just a cool place to take in, and if you are looking for some typical Italian clothing, or perfume they have a lot of good options for you. In the summer it is also a nice place to beat the heat!
If you can, book in advance and check out this great view of Venice!
