The gem of the domus is the nymphaeum fountain, richly decorated with mosaics and sculptures. It is this fountain that has lent its name to the domus, called the House of the Small Fountain to distinguish it from the House of the Large Fountain.

    The layout of the house follows the typical pattern of homes built in the early 1st century BC, featuring an entrance atrium with an impluvium (the basin used to collect rainwater), and a tablinum. The garden has peristyle walls painted with landscapes and buildings overlooking the sea.
