020 Italy - Rome - Ostia Antica Domus del Ninfeo (c. 325-350 AD) House of the Nymphaeum Along the north-west wall of the home's courtyard is a nymphaeum (shrine to the nymphs). It consists of seven rectangular and semicircular niches, in front of which are a podium and a basin. The central niche is larger than the others. Between the niches are brick columns. In the niches are remains of plaster with traces of red and blue paint. The podium and the basin were decorated with marble. On top of the podium are four sets of small steps, over which the water flowed. I liked the little stepped waterfalls.
