The Ospizio di San Michele a Ripa Grande (Hospice of St Michael) or Ospizio Apostolico di San Michele in Rome is represented today by a series of buildings in the south end of the Rione Trastevere, facing the Tiber River and extending from the bank of Ponte Sublicio for nearly 500 meters. It stands across the river from the Rione Ripa and the area known as the Porto di Ripetta, once in the Aventine neighborhood of Rome. The Porto di Ripa Grande was the river port that served those coming up from the Mediterranean port of Ostia. This area was once a main port of Rome. While large seafaring ships could not forge easily up the Tiber river to Rome; smaller boats frequently brought supplies from the coast to the city and offloaded at the Porta.
