Lato (Gr: Λατώ) was an ancient city of Crete, the ruins of which are located approximately 3 km from the small town of Kritsa. The Dorian city-state was built in a defensible position overlooking Mirabello Bay between two peaks, both of which became acropolises to the city. Although the city probably predates the arrival of the Dorians, the ruins date mainly from the Dorian period (fifth and fourth centuries BC). The city was destroyed ca. 200 BCE, but its port (Lato Etera or Lato pros Kamara), located near Agios Nikolaos was in use during Roman rule.
There is some suggestion that the city was named after the goddess Leto (of which Lato is the usual Doric form) and may be mentioned in Linear B tablets as RA-TO. Lato also minted coins in antiquity,[3] bearing the likeness of the goddess Eileithyia who appears to have been the one particularly worshipped at Lato.
Nearchus, admiral of Alexander the Great, was born at Lato.

The first habitation of the site dates from the Neolithic and Early Minoan period (3rd millenium B.C.). In the late Classical period (beginning of the 4th century B.C.) the Gortynians established the sanctuary of Asklepios at the harbour. During the tremendous earthquake of 46 B.C. the city was destroyed and subsequently rebuilt. In the Early Christian and Byzantine periods, a small settlement developed and the basilica was erected. The most important monuments of the site are:
The Temple of Asklepios., the "Treasury"., the Fountain, a large, three-aisled basilica, an Early Minoan settlement (2600-2000 B.C.), the West Stoa, the North Stoa, the Nymphaion and two large, mud-brick cisterns.
