Isola Sacra

Tor San Michele, also known as Forte San Michele, is a coastal watchtower in Ostia, a frazione of the Municipality of Rome (Italy), rising near the mouth of the Tiber. Built during the 16th century to remedy the deviation of the river following a disastrous flood, it was first used as a customs office and a lookout and defense station, then as a lighthouse for the Ostia Seaplane Base, until it fell into disuse after the end of World War II.

The Centro Habitat Mediterraneo (CHM; Italian for "Center for Mediterranean Habitat") is an oasis of 20 hectares (49 acres) on the coast near Rome (Italy), included in the Litorale Romano State Nature Reserve and managed by the Italian Bird Protection League (LIPU).

The Marina of Rome (Italian: Porto Turistico di Roma) is a tourist port that rises along the banks of Ostia, in the Municipality of Rome (Italy).

The Tiber ( TY-bər; Italian: Tevere [ˈteːvere]; Latin: Tiberis) is the third-longest river in Italy and the longest in Central Italy, rising in the Apennine Mountains in Emilia-Romagna and flowing 406 km (252 mi) through Tuscany, Umbria, and Lazio, where it is joined by the River Aniene, to the Tyrrhenian Sea, between Ostia and Fiumicino. It drains a basin estimated at 17,375 km2 (6,709 sq mi). The river has achieved lasting fame as the main watercourse of the city of Rome, which was founded on its eastern banks. The river rises at Mount Fumaiolo in central Italy and flows in a generally southerly direction past Perugia and Rome to meet the sea at Ostia. Known in ancient times (in Latin) as flavus ("the blond"), in reference to the yellowish colour of its water, the Tiber has advanced significantly at its mouth, by about 3 km (2 mi), since Roman times, leaving the ancient port of Ostia Antica 6 kilometres (4 miles) inland. However, it does not form a proportional delta, owing to a strong north-flowing sea current close to the shore, to the steep shelving of the coast, and to slow tectonic subsidence.

Giovanni Battista Grassi (27 March 1854 – 4 May 1925) was an Italian physician and zoologist, best known for his pioneering works on parasitology, especially on malariology. He was Professor of Comparative Zoology at the University of Catania from 1883, and Professor of Comparative Anatomy at Sapienza University of Rome from 1895 until his death. His scientific contributions covered embryological development of honey bees, on helminth parasites, the vine parasite phylloxera, on migrations and metamorphosis in eels, and on termites. He was the first to describe and establish the life cycle of the human malarial parasite, Plasmodium falciparum, and discovered that only female anopheline mosquitoes are capable of transmitting the disease. His works in malaria remain a lasting controversy in the history of Nobel Prizes, because a British army surgeon Ronald Ross, who discovered the transmission of malarial parasite in birds was given the 1902 Nobel Prize in Physiology or Medicine. But Grassi, who demonstrated the complete route of transmission of human Plasmodium, and correctly identified the types of malarial parasite as well as the mosquito vector, Anopheles claviger, was denied. Grassi was the first to demonstrate the life cycle of human dwarf tapeworm Taenia nana, and that this tapeworm does not require an intermediate host, contrary to popular belief. He was the first to demonstrate the direct life cycle of the roundworm Ascaris lumbricoides by self-experimentation. He described canine filarial worm Dipetalonema reconditum, and demonstrated the parasite life cycle in fleas, Pulex irritans. He invented the genus of threadworms Strongyloides. He named the spider Koenenia mirabilis in 1885 after his wife, Maria Koenen. He pioneered the foundation of pest control for phylloxera of grapes.

The Isola Sacra Necropolis was the first large-scale pagan cemetery of Roman Imperial times to be excavated. The excavator-in-chief of most of Isola Sacra was Guido Calza. The necropolis was found on the manmade island of Isola Sacra, which lies between the cities of Portus and Ostia Antica, a region just south of Rome. The emperor Trajan was in power when this artificial island was created. Much of the excavated necropolis flanked the Via Severiana, which ran through Isola Sacra and traveled southeast from Ostica to Terracina.The cemetery was extensive, and was comparable to Etruscan cemeteries and Christian catacombs. Although some tombs were constructed for the very poor, the majority of burials were built by the middle class bourgeoisie of the area. Since the burial grounds were constructed during the 2nd century and first half of the 3rd century, a historical transition is seen in the necropolis from the pagan practice of cremation to inhumation.

Santa Monica di Ostia is a 20th-century parochial church in the Lido di Ostia, Rome dedicated to Saint Monica.

Portus was a large artificial harbour of Ancient Rome. Sited on the north bank of the north mouth of the Tiber, on the Tyrrhenian coast, it was established by Claudius and enlarged by Trajan to supplement the nearby port of Ostia.The archaeological remains of the harbour are near the modern-day Italian village of Porto within the Comune of Fiumicino, just south of Rome in Lazio (ancient Latium).

The naval Battle of Ostia took place in 849 in the Tyrrhenian Sea between Muslim army and an Italian league of Papal, Neapolitan, Amalfitan, and Gaetan ships. The battle ended in favor of the Italian league, as they defeated the pirates. It is one of the few events to occur in southern Italy during the ninth century that is still commemorated today, largely through the walls named after Leo and for the Renaissance painting Battaglia di Ostia by Raphael.

Ostia (, Italian: [ˈɔstja]; officially Lido di Ostia) is a large neighbourhood in the X Municipio of the comune of Rome, Italy, near the ancient port of Rome, which is now a major archaeological site known as Ostia Antica. Ostia is also the only municipio or district of Rome on the Tyrrhenian Sea, and many Romans spend the summer holidays there.

Santa Maria Regina Pacis a Ostia Lido is a 20th-century parochial church and titular church in Ostia, southwest of Rome, dedicated to Mary, Queen of Peace.

The Museo Archeologico Ostiense (or Archaeological Museum of Ostia) is an archaeological museum dedicated to the ancient Roman city of Ostia in Rome, Italy. The museum was built by Pope Pius IX, who in 1865 had to readapt a fifteenth-century building used as a store to create a city museum. Contained in the museum are numerous archaeological objects which came to light during a long period of excavations. The collection includes, for example, a collection of portraits of famous people from ancient Ostia, including philosophers and members of the royal family, such as busts depicting Asclepius and Volcacius Myropnous, a portrait of Faustina the Elder and the head of Trajan. The museum also has a large collection of sculptures, including the statue of Perseus holding the head of Medusa, the sculptural group of Mithras slaying the bull, and other works. There are other examples on display of great interest, such as small groups in marble depicting Cupid and Psyche and other subjects, and in another section of the museum, sarcophagi and reliefs. On display are also examples of wall paintings from different burials and emblems of polychrome mosaics, such as the Christ Blessing. These works of great historical and artistic value, are then supported by a collection of minor works such as crafts, glass, and even teaches some at the shop, and some interesting facts, such as the marble slab found in the temple of Bellona, on which are carved two pairs of feet opposite, probably a votive object.
