Private Island for sale in Greece. Luxury real estate.

Trinity Island is located in the southern Gulf of Euboea (Evia). It lies 1,200 metres off the coast near the ancient city of Eretria which is located approximately in the middle of the southwestern shore of Euboea. Eretria is only 3.5 miles to the East of the town of Oropos, which is located on the shore of mainland Greece. Car ferries service the Oropos-Eretria run every 30 minutes, the crossing takes about 20 minutes. Oropos can be reached by car from Athens via the National Highway in approximately one hour. Thus the total time consumed in traveling from Athens to Trinity Island is approximately one and a half hours. Furthermore the ferry can be by-passed by using the Halkis bridge, and by this route Athens-Eretria is 108 kms. This drive also takes about one and a half hours.

Eretria used to be a very important city in ancient times. Today it is a very popular summer resort where every amenity for the daily and technical needs is available such as supermarkets, gas stations, motor repair services, boutiques, hotels, restaurants, bars, discos, including doctors, vets, and daily help for the island.

Trinity Island has roughly the shape of a guitar and covers an area of approximately 12 acres (48,000 sq.m.). Its maximum length is 650 metres and its width 150 metres. Its mean height is between 4 and 6 metres above sea level. There are rocks jutting out of the otherwise flat island.

The vegetation is very thick, consisting of 350 grown olive trees producing very good quality oil, enough per year to supply the family and many friends.
There are also 125 pistachio trees, a variety of fruit trees, among others pomegranates, apricots, peaches, almonds, plums and figs. There are numerous pine and cypress trees around the perimeter of the island, as well as hundreds of ornamental bushes such as oleanders, bougainvilleas, hibiscus, geraniums and various other shrubs which are friendly to the Mediterranean climate. All these are spread evenly along the main paths of the island.

A water well has been drilled on a 700 sq.m. plot close to the shore of Eretria, opposite Trinity Island. This plot is also owned by the family and is included in the sale of the island. A water tower has been erected over the well, at a height of 17.3 metres with a production capacity of 45 m³ of water per hour. An electric pump automatically replenishes the tank whenever the water level drops below a certain point. The said water tank is connected with Trinity Island through pipes of a total length of 1,900 metres, of which 1,200 are laid underwater, attached with chains on cement blocks at the bottom of the sea. The remaining 700 metres of pipes are to be found on the island itself. The water thus reaches Trinity Island through gravitation attained by the height of the water tank.
Caution has been taken in case of malfunction of the electric pump in the form of a reinforced concrete water tank, of a capacity of 150 m³, situated on Trinity Island itself, above the staff house. It is designed to provide the island with water, pending any kind of repair of the Euboean-based water pump.

Furthermore, a full network of plumbing and water pipes exists on the island which provides for numerous water outlets for adequate watering of almost its entire area.
The water is not very pleasant in taste but by no means health hazardous. It is used for all necessities except to drink. Most of the island is automatically watered.

Two Lister Diesel generators, housed in their own small buildings, and two smaller diesel generators close to the main house generate electricity which provides for the lighting and all the household appliances of the main house, the staff house, the beach house, the fortress and the chapel as well as the roads, the paths, and the piers, and most of the vital areas of the island.
