There’s many places where I love walking around in Ostia Antica but if I had to mention one I would choose the Domus of the Fortuna Annonaria.
This only site is worth the trip for the quantity and quality of well preserved mosaics and marbles that still decorate part of this important house dating back to the 4th century AD and built readapting a previous costruction.
Off the main road, the Decumanus Maximus, you can only get there if you know the place and for this reason most of the times the Domus is empty and gives its lucky visitors the privilege to enjoy the large spaces uniquely. Fountains and flowers used to decorate the patio as well as statues, including the Fortuna Annonaria’s which names it and represents the patron of the large storages in town. After all, this was an important role of Ostia and the local barns would feed the Capital.
Not to be missed the mosaics of the She-wolf with Romulus and Remus, Atteon turned into a deer for having spied Diana having a bath in a river and a well preserved private latrin in the back of the house!
