The tower of Krouna is located approximately 1km outside the village Ierrisos. As with many of the other towers in Halkidiki, this one was also constructed to protect the surrounding metochi. This metochi was named ‘Koroni’ after the area where it was located and was related to the Serbian monastery of Chilandar at Mount Athos. Its purpose was to protect the metochi’s facilities, from the church of Prophet Elias, along the stream until the public road near the sea. Its name "Krouna" is the exact translation from Greek word ‘koroni’ (eng. crown)’ into Serbian and the tower is still known by that name today.
The tower is constructed in a square shape with a diameter of 7 meters. The current height is 12 meters. After the construction was completed, the tower must have been significantly higher. Photos of the early 20th century show the tower with an additional floor.
The building material of the tower of Krouna, like the materials of the other towers in the area, were mainly obtained by the abstraction from buildings of the ancient city of Akanthos and the ancient Ouranoupolis.
The tower was protected by a fortified enclosure which also contained the warehouses, stables and the winery. Parts of the north and east sides of the fortification are preserved, with a total length of about 40 meters and a height of 2.5 meters. Further sections appeared to be deconstructed and removed as materials for newer buildings.
