The Fortezza castle, at the top of a low hill named "Palaiokastro" dominates the town. It was built in 1590 to protect the city from the pirates raids and the Turks.
The name "Palaiokastro which means 'The old Castle' was in use even by the Venetians which demonstrates the existance of an even older castle at this place. - Probably the acropolis of the ancient town of Rithymna.
The interior of Fortezza accommodated the following basic buildings: the storeroom of the artillery, where canons and weapons were kept, the residence of the Councilors, where one of the city's two Venetian councilors lived, the residence of the Rector, which represented a luxurious, magnificent building in the central square of the fortress.
Today parts of those buildings, as well as of some others built later, can be seen. The view from up there is magnificent, especially at night.
The municipal theatre "Erofili" stands also at Fortezza's premises. It is an outdoor theatre that hosts almost all the performances during the Renaissance Festival.

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.
