Acrocorinth (Greek: Ακροκόρινθος, lit. 'Upper Corinth' or 'the acropolis of ancient Corinth') is a monolithic rock overseeing the ancient city of Corinth, Greece. In the estimation of George Forrest, "It is the most impressive of the acropolis of mainland Greece." With its secure water supply, Acrocorinth's fortress was repeatedly used as a last line of defense in southern Greece because it commanded the Isthmus of Corinth, repelling foes from entry by land into the Peloponnese peninsula. The Acrocorinth was continuously occupied from archaic times to the early 19th century. Along with Demetrias and Chalcis, the Acrocorinth during the Hellenistic period formed one of the so-called “Fetters of Greece” – three fortresses garrisoned by the Macedonians to secure their control of the Greek city-states. The city's archaic acropolis was already an easily defensible position due to its geomorphology; it was further heavily fortified during the Byzantine Empire as it became the seat of the strategos of the thema of Hellas and later of the Peloponnese. It was defended against the Crusaders for three years by Leo Sgouros. Afterwards it became a fortress of the Frankish Principality of Achaea, the Venetians, and the Ottoman Turks. Three circuit walls formed the man-made defense of the hill. The highest peak on the site was home to a temple to Aphrodite. The temple was converted to a church, which in turn was converted to a mosque. The American School's Corinth Excavations began excavations on the Acrocorinth in 1929. Currently, it is one of the most important medieval castle sites of Greece.

The Archaeological Museum of Ancient Corinth is located within the archaeological site of Ancient Corinth and is dedicated to displaying the numerous findings from the surrounding excavations. It is a small but rich museum, established in 1931 to host the findings of the American School of Classical Studies at Athens, and it is housed in a modern building that was renovated in 2004. The museum's collection includes exhibits that showcase the rich cultural heritage of Ancient Corinth from prehistoric times to the Roman era. It features a wide range of artifacts, including pottery, sculptures, coins, jewelry, and other objects that provide insight into the daily life, religious practices, and artistic achievements of ancient Greece. Some of the most notable exhibits in the museum include the terracotta figurines from the Sanctuary of Demeter and Kore, which depict the goddess Demeter and her daughter Persephone, and the impressive statues of Roman emperors and members of the imperial family. The museum also houses multimedia exhibits and interactive displays that help visitors gain a deeper understanding of the artifacts and their historical context. Overall, the Museum of Ancient Corinth is an important cultural attraction that provides visitors with a glimpse into the rich history and culture of Ancient Corinth.

The Archaeological Site of Ancient Corinth is an important historical site in Greece located about 78 km southwest of Athens. Corinth was one of the major cities of ancient Greece, and its ruins provide valuable insights into the ancient Greek civilization and the daily life of its people. The archaeological site of Ancient Corinth covers a large area and includes several notable ruins, such as the Temple of Apollo, the Agora (marketplace), the Peirene Fountain, and the Bema (judgment seat). The temple of Apollo was one of the most important sanctuaries in Ancient Corinth and was built in the 6th century BCE. It was dedicated to Apollo, the god of light, music, and poetry, and was a center for religious and cultural activities. The Agora was the center of commerce and civic life in Ancient Corinth and was surrounded by important buildings such as the courthouse, the prison, and the mint. The Peirene Fountain was the main source of water for the city and was a popular spot for social gatherings. The Bema, or judgment seat, was a raised platform where the city officials and judges would make their decisions. Visitors to the Archaeological Site of Ancient Corinth can explore the ruins of these and other important buildings, as well as see artifacts that have been excavated from the site. The site also provides stunning views of the surrounding countryside and the Gulf of Corinth.
