Tentative Excursions and Suggested Sightseeings

1. Elafonisi Excursion: An island protected by NATURA

Elafonisi IMG 7419 Compressed    Elafonisi DSC 0081 Compressed

Elafonisi is one of the most rare and beautiful landscapes in all Europe: an extensive beach of unique beauty that overlooks the Libyan sea and an island that you can even walk to it.The water is not higher than an adult's knee! Here, we can find a kind of cedar tree and sand lilies that grow nowhere else in Europe. An area of about 2,000 acres of the seaside is protected by "NATURA 2000". All facilities are pretty much underdeveloped (parasols and small canteens), so it would be a good idea to bring along supplies (mostly water).

2. Knossos Archeological Excursion

knossos 1024x768

Knossos is the largest Bronze Age archaeological site on Crete and has been called Europe's oldest city. The palace of Knossos was the political center of the Minoan civilization. It is the largest of the preserved Minoan palatial centers. Four wings are arranged around a central courtyard, containing the royal quarters, workshops, shrines, storerooms, repositories, the throne room and banquet halls.

Knossos city was undeniably the capital of Minoan Crete. It is grander, more complex, and more flamboyant than any of the other palaces known to us, and it is located about twenty minutes south of the modern port town of Iraklion City. 

Knossos was inhabited for several thousand years, beginning with a neolithic settlement sometime in the seventh millennium BC, and was abandoned after its destruction in 1375 BC which marked the end of Minoan civilization. It was destroyed for the first time along with the other Protopalatial palaces around Crete at 1700 BC, probably by a large earthquake or foreign invaders. It was immediately rebuilt to an even more elaborate complex and until its abandonment was damaged several times during earthquakes, invasions, and in 1450 BC by the colossal volcanic eruption of Thera, and the invasion of Mycenaeans who used it as their capital as they ruled the island of Crete until 1375 BC. 

Walking through its complex multi-storied buildings one can comprehend why the palace of Knossos was associated with the mythological labyrinth. The Labyrinth was the dwelling of the Minotaur in Greek mythology, and many associate the palace of Knossos with the legend of Theseus killing the Minotaur. 

The Greek myth associated with the palace about Theseus and the Minotaur is fascinating, but walking around the ruins of Knossos today it is hard to imagine it to be a place of torment and death. Instead, the palace radiates with joyous exuberance through the elaborate architectural planes and volumes that were clustered around the central courtyard over time. The elegant wall frescoes which decorated the walls speak of a people who approached the subtleties of life and the splendor of nature with a joyous disposition.

We follow up our tour with a visit to the Archaeological Museum in Heraklion. The most magnificent collection of Minoan art and culture in the world, unique in beauty and completeness is housed in the Museum of Iraklion, a modern building specifically designed for this purpose.

There are twenty rooms- galleries on the ground and first floors and the usual visit takes at least two hours but, of course, several days are necessary for the visitor who wishes to linger and study more carefully the exhibits, which cover a period of 5,000 years, from neolithic era to Graeco Roman period.


 3. Archaeological Museum in Heraklion

The Heraklion Archaeological Museum is one of the oldest and most important museums in Greece, and among the most famous museums in Europe. It houses representative artefacts from all periods of Cretan prehistory and history, covering a chronological span of over 5,500 years from the Neolithic period to Roman times. The Heraklion Archaeological Museum prides itself for its unique Minoan collection, which includes the masterpieces of Minoan art. It is rightly considered as the Museum of Minoan Culture par excellence.

Located in the town center of Heraklion, it was designed by the architect Patroklos Karantinos and was built between 1935 and 1958 on a site previously occupied by the Venetian monastery of Saint-Francis which was destroyed by earthquake in 1856.

The Heraklion Archaeological Museum is a Special Regional Service of the Ministry of Culture. Along with the permanent exhibition, the museum organizes temporary exhibitions in Greece and abroad, creates and implements educational programs, collaborates with scientific and scholarly institutions, and houses a variety of cultural events.

4. Archaeological Museum of Chania

The Museum is located in the historic centre of Chania. The permanent exhibition illustrates, through archaeological testimonies, the cultural history and character of the area through the ages, from the Neolithic period to the Roman era (4th millennium BC - 3rd c. AD). The Museum collections contain finds from the Neolithic sites (mainly caves), settlements and cemeteries of the Minoan and Historic periods found in Chania Prefecture. These include important Minoan finds from the excavations on Kastelli Hill in the city of Chania, which most scholars identify with the Minoan and Classical city of Cydonia, the major centre of power of West Crete in antiquity.

5.  Mountains of Crete

Apart from the unique beaches in Crete, there are also alpine regions engraved by the pure Cretan attribute. Spring is the most ideal season for someone to visit high crowns (for example in White Mountains in Chania or Pseiloritis in Rethimno) offering life-changing emotions, the Omalos plateau in Chania where someone can combine hiking with truly traditional Cretan food and “raki” at the local villages, or even the Samaria Gorge. This unique gorge in Crete is 16km long and leads to a revitalizing beach in Agia Roumeli (Sfakia)

Gastronomy of Crete

Cretan cuisine is based on local products: fruits, vegetables, pulses, and herbs are deliciously combined with goat meat, creating most imaginative dishes that aren’t found anywhere else.

SeRAC: Sentinel-3 Radar Altimeter Calibration Site in Crete

Serac crete eu


FRM4ALT is continued in the Sentinel-3 Radar Altimeter Calibration in Crete (SeRAC) activity with Operational Support, now in place. The objective of this SeRAC project is to ensure the routine operations and maintenance of the CDN1 transponder Cal/Val site for Sentinel-3A but also for Sentinel-3B Commissioning and Routine Operational Phase. The transponder Cal/Val operations shall be further supported by the sea-surface Cal/val sites established at the Permanent Facility for Altimetry Calibration in west Crete, Greece.
