The sanctuary of the Egyptian deities (1st-2nd centuries A.D.) is the only one, in the whole island, which is dedicated to the Egyptian gods Isis, Serapis and Anubis - Hermes although it is known that those gods are worshiped in other cities.
The sanctuary consists of quadrilateral nave, arcade on the west, underground crypt in the south and a cistern outside east of nave. In the central alcove stood the statue of Serapis and the side statues of Isis and Hermes - Anubis. In the southern part of the temple was oblong space, underground crypt purification and a small cictern. The final construction phase of the temple dates to the 1st / 2nd century. AD, in accordance with dedicatory inscription.

The Temple of Apollo Pythios (Pythian Apollo) located in the center of the ancient Agora, was excavated in 1887 and was the largest temple and the religious center of ancient Gortyn until the introduction of Christianity and the founding of the basilica of St. Titus around 500 AD.
The first building of the seventh century. BC was a four-sided enclosure with four wooden pillars in the center to support the roof. The exterior walls and stairs of the crepis were covered with archaic inscriptions. In the Hellenistic period a monumental anteroom was added while columns with inscriptions were placed between the pillars. Alterations and additions were made during the Roman period. Outside the temple was built a magnificent altar on a stepped base while in the west of the temple was built a small theatre.
In the middle Byzantine period in the vicinity of the temple, which had been abandoned, were built houses and aqueducts.
Many finds have been made in the temple among which the colossal statue of Apollo Pythios and many inscriptions with administrative and law content of the Archaic and Hellenistic period. Dates: 7th c BC; Hellenistic; 2nd c AD.

The Praetorium was the seat and residence of the proconsul of Crete. It is divided into two parts: the administrative section, in which the central building is the basilica, and the more "private" sector. The preserved ruins are dated to the 2nd century A.D. and seem to have been repaired in the 4th century A.D.
This totally excavated building is the largest in the whole City of Gortyn. The earliest constructions have suffered successive alterations in a long period of eight centuries. New structures were erected on the ruins of the earlier sometimes incorporating parts of them. In the 1st c AD the Praetorium consisted of a peristyle court 1000 sq.m. and large halls to the north and west. This first Praetorium was destroyed by an earthquake in the time of the Emperor Trajan (early 2nd c AD). It was reconstructed and a large Thermai complex was built at its east side. Some years later a large temple dedicated to the Augusts was built further at the east part. To the west of the Thermai the juridical basilica continued to function under a judge’s responsibility according to the inscriptions found there, and statues of the emperors and other officers were still standing there. All these famous buildings were destroyed by the large earthquake in 365 AD. In 383 the consul Oecumenius Asclepiodotus Dositheus, agreeing with the capital of the empire, took care of the construction of the new Praetorium.

The Great Nymphaeum (Nymphaion GR: Νυμφαίον), located to the north of Praetorium, was a marble construction with a covered cistern and fountains. Statues of Nymphs stood in the niches. The area of the remains is closed to the public but visitors can see it from a distance.

This unique monument has been excavated in the last thirty years. It is located on the road between the Saint Titos Church and the village Mitropolis. It is the largest early Byzantine basilica in Crete and among the largest in whole Greece. In early Byzantine period it was the cathedral of the city. The first five-aisled basilica was erected here in the early 6th c., in the years of the Emperor Justinian and stood for about 70 years. The central aisle had a mosaic pavement decorated in geometric patterns and animals. It is believed that there were mosaics of stone and glass tesserae on the walls, too. The other aisle had pavements of limestone slabs. The columns were made of white and gray white marble. Of great importance is the pulpit, which resembles that of Saint Sophia in Constantinople. It was a high exedra on low columns and two stairs for ascent and decent. The choirs stood under the exedra. After the destruction of the first basilica in 620 AD, a new basilica was built over its ruins in the time of the Emperor Heraclios. This basilica, following the fortune of the whole city, was destroyed after the strong earthquake of 670 AD.

It lies at the south eastern part of the city and it is considered to be largest of all theaters in Gortyna. Although it is not yet excavated, it is believed that it had a two storeyed stage and its cavea was supported by 56 arches. The statue of the seated philosopher that we see next to the exhibition hall of the archaeological site was found here.
