The Domus is a very different experience of Rome compared to everything else. The guided tour takes you through a series of chambers under a government building where you walk on glass over the excavated remains of ancient Roman baths, houses, and ruins.
The use of multimedia helps one to better understand how the ruins used to look and functioned, which can really brings them to life.
Some of the ruins are very well preserved and really make you gape in wonder.
The tour takes about an hour and a half and we highly recommend it. It's good value and the groups are quite controlled so you get a chance to look at the ruins, although in some of the smaller chambers you sometimes have to peer through people and their legs to get a better view.
We recommend booking online at least a week in advance. The booking website can be quite confusing. It rejected our application a few times saying we had missed certain boxes even though we had already filled them in. We had to try a few times for it to finally work, so keep trying!
