With the purpose of collecting all the archaeological findings of the prefecture, the Archaeological Museum of Kilkisoperates since the early 70s and includes findings from: A) the Prehistoric period. Among them, the Neolithic figurines from the village of Colchida and collection of prehistoric tools from the same village; B) the archaeological site of the cemetery of the Iron Age in PalaioGynaikokastro; C) thehistorical times such as sculptures, pottery, jewelry and other objects of everyday life.

Among the impressive sculptures there is also theKouros of Europos, dated at the end of the 6th century BC, the four statues from theHeroonof Palatiano of the 2nd century AC, the statue of the god Dionysus, also from Palatiano and the statues of the gods Apollo and Aphrodite from the region of Mikrodasos and Chorygi respectively.

This old high school was built in the late 19^th century and operated as a Bulgarian primary school. During the battle of 1913 it got nearly destroyed.

The division of its face into three parts, the decorative columns that indicate the entrance and scale, the ornate lintels with decorative wedges that point to forms of late neoclassicism, which is the dominant trend in the architecture of that period. It is currently being renovated for use as a folklore museum.

In the permanent exhibition of Paleontology the rich paleontological treasure of animal fossils and other findings of the Cave in St. George’s hill inKilkisare hosted, as well as other interesting exhibits such as the model of the dotted hyena of the cave, the "caver", the representation of the wild mule, etc. which date back to the last Ice Age.

These bones belonged to animals that have now disappeared from Europe due to the climate change, such as: the spotted hyena cave, the giant weasel, giant deer, primitive ox, wild horse and the wild mule. The fossils tell us a great story about the last 30.000 years in the region of ​​Kilkis, when the hill of St. George was a dangerous den of hyenas. The first findings were discovered in the 60s, when the excavation began in the cave of Kilkis, but the report was only created in 2012. The scientific study, in collaboration with the Department of Geology of the Aristotle University of Thessaloniki, revealed significant results, such as a very high concentration of wild mule bone, Equushydruntinus, which is the largest in the world.

The exhibition of Paleontology is housed on the 2nd floor of the cafeteria on St. George's Hill, about 300 meters from the corresponding cave. It is a bilingual exhibition of modern design and graphics that represents the past with an attractive and understandable manner.

On the interactive table (design of NtikMol) a dummy of a dotted hyena and informational material for the different categories of large carnivores (wolf, hyena, lion, saber) can be found.

The uniqueness of the cave is the number of bones-almost 300- from the wild mule, which have been found inside; a number that is the most populous in the world.

The museum was built in 1966. It belongs to the Ministry of Defense, which is authorized for its operation. The visitor can see in the halls of the museum documents from 1912-1913, as well as personal belongings of the officers who participated in the battle of Kilkis: uniforms, weapons (mortars, grenades, guns, etc.) and regimental flags. 

One of great interest is the relief map and the audio-visual presentation of the battle.There is also a miniature of the battleship Kilkis here.

Just a few kilometers south of Kilkis lies the archaeological site of Colchida, that stretches on the east bank of Gallikos River. Its foundation dates back to the 4^th

AC century and it was probably preserved during the Ottoman rule, since the Turks called the villages of ColchidaAktse-Klise (Asproklissi, i.e.White church).

In the area there are traces of fortification of uncertain chronology, but also ruins of a Christian basilica of the 5^thor early 6^thcentury, that was converted to a Catholic monastery during the 9^th or 10^th century. The complex was destroyed and later rebuilt during the 11^thcentury.The church has some of the best examples of Byzantine painting of the late 12^thcentury.

In order to house the works of important Greek artists, the association M.K.E. "TECHNI" – Annex ofKilkisis building a gallery in the village Metalliko, on land donated by the Municipality of Kilkis and the Agricultural Cooperative. 

These projects, which for many years enriched the collection of "TECHNI" are offered from artists whose exhibitions are occasionally hosted in the association.

Excavations that took place in August 1984 by the XVI Prehistoric and Classical Antiquities Agency of Thessaloniki, on the SE side below the castle revealed interesting archaeological findings. The reason for the excavation was the deep plowing which was the cause for revealing cinerary vases with bronze grave goods, belonging to the residents of the settlement. It was the cemetery of the settlement that had the form of a large mound of stone pile that covered the funerary vases

During excavation of 1984, three sections were made thatrevealed a burial and about 70 pots containing an equal number of cremations.The majority of these were wine amphorae that had smaller vessels as a cover, usually bowls.Their decoration was simple, almost geometric; horizontal grooves on the body or carved triangles in radial arrangement around the neck, but there are many undecorated as well.

The variety of grave goods that accompanied the dead is impressive and perhaps indicative of their sex.One category are the jewelry, such as bronze spiral bracelets, rings with double spiral end, collars of twisted wire and a plethora of gilt bronze items that must have decorated garments. In this category, a unique little gold ring is distinguished.

Another category are the iron weapons, usually swords and knives that obviously belong to men.The bronze double axes found in the excavation are of great interest and reminisce of similar ones found in Minoan Crete.
