The House of the Trifolium is the largest of the surviving private dwellings at Dougga, named for the three-lobed trifolium-shaped basin in its central court. The mosaic floors and the basic spatial logic of the house — an open peristyle court with rooms arranged around it — are intact, and you can wander into and out of the individual rooms freely.
The house gives a sense of upper-class urban life in Roman Africa that the public monuments cannot: how the rooms connected, where the slaves slept, where the diners reclined. Walk slowly and let your eye adjust to the scale. Several adjacent houses are also open and free to explore.
