Selçuk in the context of "Council of Ephesus"

The Library of Celsus (Greek: Βιβλιοθήκη του Κέλσου) is an ancient Roman building in Ephesus, Anatolia, located near the modern town of Selçuk, in the İzmir Province of western Turkey. The building was commissioned in the years 110s CE by a consul of the Roman Empire, Tiberius Julius Aquila Polemaeanus, as a funerary monument for his father Tiberius Julius Celsus Polemaeanus, former proconsul of Asia, and completed during the reign of the Roman Emperor Hadrian, sometime after Aquila's death.

The Library of Celsus is considered an architectural marvel, and is one of the few remaining examples of great libraries of the ancient world located in the Roman Empire. It was the third-largest library in the Greco-Roman world behind only those of Alexandria and Pergamum, and is believed to have held around 12,000 scrolls. Celsus is buried in a crypt beneath the library in a decorated marble sarcophagus. The interior measured roughly 180 square metres (2,000 square feet).

Ephesus (/ˈɛfɪsəs/; Ancient Greek: Ἔφεσος, romanized: Éphesos; Turkish: Efes; may ultimately derive from Hittite: 𒀀𒉺𒀀𒊭, romanized: Apāša) was an ancient Greek city on the coast of Ionia, in present-day Selçuk in İzmir Province, Turkey. It was built in the 10th century BC on the site of Apasa, the former Arzawan capital, by Attic and Ionian Greek colonists. During the Classical Greek era, it was one of twelve cities that were members of the Ionian League. The city came under the control of the Roman Republic in 129 BC.

The city was famous in its day for the nearby Temple of Artemis (completed around 550 BC), which has been designated one of the Seven Wonders of the Ancient World. Its many monumental buildings included the Library of Celsus and a theatre capable of holding 24,000 spectators.

The Temple of Artemis or Artemision (Greek: Ἀρτεμίσιον; Turkish: Artemis Tapınağı), also known as the Temple of Diana, was a Greek temple dedicated to a localised form of the goddess Artemis (equated with the Roman goddess Diana). It was located in Ephesus, near modern day Selçuk in Turkey). While it had been destroyed and rebuilt many times in ancient history, the last incarnation of the temple was destroyed in 401 CE. Only foundations and fragments of the last temple remain in the present day.

The beginning of the history of the temple is unclear. It is known, however, that the earliest version of the temple was destroyed by a flood in the 7th century BCE. A more elaborate reconstruction of the temple began around 550 BCE under the leadership of the Greek architect from Crete Chersiphron, funded by Croesus of Lydia. This version of the temple lasted until 356 BCE, when it was burned down by an arsonist, popularly identified as Herostratus.

Küçük Menderes ("Little Meander"), Cayster River, Caystrus River or Kaystros River (Ancient Greek: Κάϋστρος, romanized: Káÿstros) is a river south of İzmir, Turkey. It generally flows westward and arrives at the Aegean Sea at Pamucak beach, near Selçuk, İzmir.

The ancient city of Ephesus was once an important port on the river, but over the centuries, sedimentation gradually filled in the inlet around the city. The ancient port of Panormus was near its mouth. The coastlines moved seaward, and the ruins of Ephesus are now some 8 km (5.0 mi) inland from the coast.

The Church of Mary (Turkish: Meryem Kilisesi) was an ancient Christian cathedral dedicated to the Theotokos ("Mother of God", i.e., the Virgin Mary), located in Ephesus (near present-day Selçuk in Turkey). It is also known as the Church of the Councils because two councils of importance to the history of Early Christianity (the Council of Ephesus and Second Council of Ephesus) are assumed to have been held within. The church is located in the south stoa of the Olympieion (Temple of Hadrian Olympios) next to the harbor of Ephesus.
