Myrtoan Sea in the context of "Argolis"

The Sea of Crete (Greek: Κρητικό Πέλαγος, Kritiko Pelagos), or Cretan Sea, is a sea, part of the Aegean Sea, located in its southern extremity, with a total surface area of 45,000 km (17,000 sq mi). The sea stretches to the north of the island of Crete, east of the islands of Kythera and Antikythera, south of the Cyclades, and west of the Dodecanese islands of Rhodes, Karpathos and Kassos. The bounding sea to the west is the Ionian Sea. To the northwest is the Myrtoan Sea, a subdivision of the Mediterranean Sea that lies between the Cyclades and Peloponnese. To the east-southeast is the rest of the Mediterranean Sea, sometimes credited as the Levantine Sea. Across the island of Crete, to the opposite shore of it begins the Libyan Sea. Ferry routes to and from Piraeus and Heraklion, as well as the southern islands of the Aegean and the Dodecanese, run in this area.

Just off the coastline of Northeastern Crete, the sea reaches a maximum depth of near 3,293 m (10,000 ft). Other sources (maps) show a maximum depth of 2,591 m (8,500 ft).

Hydra, or Ydra or Idra (EE-dra; Greek: Ύδρα, romanized: Ýdra, pronounced [ˈiðra] in Modern Greek), and in antiquity Hydrea, is one of the Saronic Islands of Greece, located in the Aegean Sea between the Myrtoan Sea and the Argolic Gulf. It is separated from the Peloponnese by a narrow strip of water. In ancient times, the island was known as Hydrea (Ὑδρέα, derived from the Greek word for "water"), a reference to the natural springs on the island.

The municipality of Hydra consists of the islands Hydra (area 49.6 km (19.2 sq mi)), Dokos (area 13.5 km (5.2 sq mi)), and a few uninhabited islets, with a total area of 64.443 km (24.9 sq mi). The province of Hydra (Greek: Επαρχία Ύδρας) was one of the provinces of the Argolis and Corinthia Prefecture from 1833 to 1942, of Attica prefecture from 1942 to 1964, of Piraeus prefecture from 1964 to 1972, and of Attica again as part of the newly established Piraeus prefecture of Attica. Its territory corresponded with that of the current municipality. It was abolished in 2006. Today the municipality of Hydra is part of the Islands regional unit of Attica region.

In Greek mythology, the name Myrto (Ancient Greek: Μυρτώ, romanized: Murtṓ, lit. 'myrtle') may refer to one of the following characters:

• Myrto, a possible eponym for the Myrtoan Sea.
• Myrto, one of the Maenads who followed Dionysus in the Indian War.
• Myrto, an Amazon and one of the possible mothers of Myrtilus by Hermes.
• Myrto, daughter of Menoetius of Opus, sister to Patroclus. She had a daughter Eucleia by Heracles.

Monemvasia (Greek: Μονεμβασιά, Μονεμβασία, or Μονεμβάσια) is a town and municipality in Laconia, Greece. The town is located in mainland Greece on a tied island off the east coast of the Peloponnese, surrounded by the Myrtoan Sea. Monemvasia is connected to the rest of the mainland by a tombolo (sandy isthmus) 400 metres (1,300 ft) in length.

In 1890, a small part of the natural tombolo was cut to create an artificial bridge for ships and boats. Its area consists mostly of a large plateau some 100 m (330 ft) above sea level, up to 300 m (980 ft) wide and 1 kilometre (0.62 mi) long.
