Situated away from the sea and well-protected from pirates, this area was inhabited by Illyrians, and from the Roman times, an inscription was found. The XVIth century parish church of Sveti Martin is situated on the hill of Mratinovo; it is a favorite spot for walkers and is known for its church tower surrounded by ancient pine trees. Sveti Roko's Church in Postrana also commands a nice view from its big round stone terrace with very old "kostili" trees. The church of Sveti Vid is the oldest church in Zrnovo and one of the oldest in the region (around 1300).

The traditional, Mostra is performed in front of this church, as are other local festivities. Another item of interest in Zrnovo is the great number of Dalmatian stone boundary-walls "meje" which support the terraced vineyards. One of the bestknown and best-preserved "Kastel" in Zrnovo is in Postrana; it belonged to the respected diplomat Jakov Banicevic (1466-1532), a friend of Erazmus of Rotterdam. Jakov Banicevic (Jacobus de Bannisis) was born on October 15 1466. He was a great European diplomat, counsellor and the envoy of the emperors Maximillian I and Charles V, the friend of Erasmus from Rotterdam, Albrecht Dürer, Pietro Bemba; he died in Trento on December 19 1532. The memorial plaque was put on his native house in 1646. Erasmus from Rotterdam said about this man: "He is the man honoured by numerous various abilities". The best known man from Zrnovo today is the great Croatian writer Petar Segedin, who described his native Zrnovo in numerous pages of his rich work.

The inhabitants of Zrnovo, from ancient times until today, were skilled and talented craftsmen, especially stonecutters and builders. But they never abandoned their fields, on which most of all cultures, they would cultivate vineyards; from them, they would make the intoxicating wine PLAVAC. To the visitor of today, especially interesting are the terracelike stone walls which enclosed the stingy soil that nourished this ancient Mediterranean culture. The cove under these vineyard terraces on the southern side of the Island of Korcula today is available to the more persistent tourists. The Zrnovo inhabitants gave them the mutual name "defora", while in the navigational maps they are recorded as: Orlandusa, Gostinja Vala, Rasohatica, Pavja Luka.

Not far from the Zrnovo hamlet of Brdo above the cove of Vrbovica lies Kocije. an area of chalk dolomites of various forms with a fresh water well. This is a very attractive excursion point and is easily accessible.

Zrnovska banja, Vrbovica, Ostri rat, Tri zala,

A local road leads from Korcula towards the west to the picturesque coves and inlets: Medvinjak, Zrnovska Banja, Vrbovica, Ostri Rat, Tri zala, Kneza. In some of these places, life developed as early as in the classic and Roman times. In the Zrnovska Banja Cove, there are ruins of an elongated and vaulted double building. It was most probably a large cistern for the water supply of the inhabitants and the ships. But, there is a possibility that they were in fact remnants of an ancient bath, built on the basis of medicinal mud springs, which can be found in Korculan coves. Even today, in the Kneza Cove, a Roman mosaic exists; it served as a floor for an existing field cottage. Today, in all of these coves and inlets, modern, comfortable homes are built or are in the process of being built, not only for housing purposes but also for renting to the everchoosy tourists in their search for new locations on this island of variety.
