Corinthia in the context of "Megaris"

Corinth (/ˈkɒrɪnθ/ KORR-inth; Greek: Κόρινθος, romanized: Kórinthos, Modern Greek pronunciation: [ˈkorinθos]) is a municipality in Corinthia in Greece. The successor to the ancient city of Corinth, it is a former municipality in Corinthia, Peloponnese, which is located in south-central Greece. Since the 2011 local government reform, it has been part of the municipality of Corinth, of which it is the seat and a municipal unit. It is the capital of Corinthia.

It was founded as Nea Korinthos (Νέα Κόρινθος), or New Corinth, in 1858 after an earthquake destroyed the existing settlement of Corinth, which had developed in and around the site of the ancient city.

The Gulf of Corinth or the Corinthian Gulf (Greek: Κορινθιακός Κόλπος, romanized: Korinthiakós Kólpos, Greek pronunciation: [koɾinθiaˈkos ˈkolpos]) is an inlet of the Ionian Sea, separating the Peloponnese from western mainland Greece. It is bounded in the east by the Isthmus of Corinth which includes the shipping-designed Corinth Canal and in the west by the Rion Strait which widens into the shorter Gulf of Patras (part of the Ionian Sea) and whose narrowest point has been crossed since 2004 by the Rio–Antirrio bridge. The gulf is bordered by the large administrative divisions (regional units): Aetolia-Acarnania and Phocis in the north, Boeotia in the northeast, Attica in the east, Corinthia in the southeast and south and Achaea in the southwest. The tectonic movement across the gulf is comparable to parts of Iceland and Turkey, growing by 10 mm (0.39 in) per year.

In the Middle Ages, the gulf was known as the Gulf of Lepanto (the Italian form of Naupactus).

Argolis or Argolida (Greek: Αργολίδα Argolída [arɣoˈliða]; Ἀργολίς Argolís [arɡolís] in ancient Greek and Katharevousa) is one of the regional units of Greece. It is part of the region of Peloponnese, situated in the eastern part of the Peloponnese peninsula and part of the tripoint area of Argolis, Arcadia and Corinthia. Much of the territory of this region is situated in the Argolid Peninsula.

Geraneia Mountains or Yerania Ori (Greek: Γεράνεια Όρη) are a mountain range in Corinthia and West Attica, Greece. Its highest point is the peak Makryplagi (Greek: Μακρυπλάγι), elevation 1,351 m. It covers the northern part of the isthmus between the Gulf of Corinth and the Saronic Gulf. It spans 5–10 km from north to south and 30 km from east to west.

The geography of Geraneia includes forests in the south, the west and the northern part at an elevation of under 900 to 1,000 m. Barren land is in the central part. The grasslands and some bushes lies to the northwest. Farmlands and some barren land lies to the south.

Sicyon (/ˈsɪʃiˌɒn, ˈsɪs-/; Greek: Σικυών; gen.: Σικυῶνος) or Sikyōn was an ancient Greek city state situated in the northern Peloponnesus between Corinth and Achaea on the territory of the present-day regional unit of Corinthia. The ruins lie just west of the modern village of Sikyona (previously Vasiliko). An ancient monarchy at the times of the Trojan War, the city was ruled by a number of tyrants during the Archaic and Classical period and became a democracy in the 3rd century BC. Sicyon was celebrated for its contributions to ancient Greek art, producing many famous painters and sculptors. In Hellenistic times it was also the home of Aratus of Sicyon, the leader of the Achaean League.

Argolis and Corinthia Prefecture (Greek: Νομός Ἀργολίδος καὶ Κορινθίας), commonly known as Argolidocorinthia (Ἀργολιδοκορινθία), was one of the prefectures of Greece. Its capital was Nafplio. It was one of the first prefectures established, first in 1833–1836 and again from 1845 until 1899, when it was split into Argolis Prefecture and Corinthia Prefecture. The split was reversed in the 1909 administrative reform, and the prefecture existed until split again in 1947.

The northern half became Corinthia with its capital at the city of Corinth, the southern half became Argolis with its capital at Nafplio. The islands Hydra, Spetses, and Kythira in the south became part of the Attica Prefecture.
