Sivritos (GR: Σίβρυτος) was an important and autonomous city of the ancient Crete. The city was built in the location that today is the village of Thronos. It was located on a hill dominating the valley of Amari. The name Sivritos is derived from the words si, that in the ancient eastern languages meant water, and the word vriti, that is of prehistoric origin and meant sweet. Therefore, Sivritos in the Minoan period meant sweet water. The derivation is also verified by the fact that near the hill where the city was located there are numerous sweet water springs.
The village of Apodoulou is located 55 km from Rethimno at an altitude of 450m. Remains of an extensive centre of the Old Palace period (1950-1700 B.C.) have been uncovered.at the site called Gournes, near the village of Apodoulou, at the west foot of Psiloreitis. The site dominates the Amari valley and controls the main route to the Messara plain. Excavations have brought to light three building complexes while tholos tombs of the Postpalatial period (1380-1200 B.C.) have also been located in the adjacent area. The first excavations on the site were carried out by S. Marinatos in the 1930's. During World War II it was excavated by the German Archaeological Institute, under the direction of E. Kirsten. Since 1985, systematic excavations have been carried out by the Greek Ministry of Culture in collaboration with the University of Naples.
The most important monuments on the site are: Building A. It lies on the east side of the hill, to the south of the massive retaining wall. It had two storeys, as is indicated by the two preserved steps of a staircase. Decades of pithoi and other vases found on the ground floor suggest that it was used for storage. The house was destroyed by fire which followed an earthquake.
Building B, located to the north of the retaining wall. It is a complex of rooms which originally communicated with Building A.
Building C. It lies to the east of house A and belongs to a later phase of the settlement.
Tholos tomb at Sopatakia. Tholos tomb with dromos, lying to the east of the road that leads from Apodoulou to Nithavris. The dromos is 7 m. long and the chamber has a diameter of 3.10 m. Three larnakes were found inside the burial chamber. Dated to 1380-1200 B.C.
Monastiraki lies in the valley of Amari, on the natural route leading from northern Crete to the Messara plain. Excavations have brought to light a centre of the Old Palace period (1950-1700 B.C.). which was destroyed by fire following an earthquake. The large number of storerooms and the existence of two archive rooms with many clay sealings indicate a palatial character for the site. Other finds on the top of a neighbouring hill suggest there must have been a religious centre in the area, as well.
