Church Katopoliani is one of the key remains in the Cyclades. The name probably derives from the name of the town Katapola (a household name on other islands in the Aegean Sea). The name Ekatontapyliani associated contrast to the legend of the 100 ports (ekaton Pyles), which is probably a ordvariant of the place name. According to tradition linked the rising of Panagia temple to saint Eleni (see above).
This is a cruciform basilica with colonnades that shape the aisles and originally had a ceiling of wood. During the reign of Justinian (527-565) were replaced the roof and installed arches and a dome with skylights. The building is complemented by a narthex, a baptismal font and the chapel of Agios Nikolaos, whose architectural elements almost exclusively from ancient buildings. During the post-Byzantine years built Agia Theodosias Temple (1619) on the north outside of the big church and the chapel of Agios Dimitrios on the eastern side of the southern colonnade, and cells.
Ancient Architectural Elements
It was very common to use the ancient architectural elements in the building of Christian temples.
According to estimates, they used more than 2,500 antique architectural elements during erection of Panagias temples, the baptismal font and the chapel of Agios Nikolaos. Marmorpilastrarna available to the right and left of the entrance of the main temple Panagias comes from a neoclassical altar is decorated with triglyphs dedicated to Zeus Eleftherios as stated in the inscription carved into the triglyferna.

All arches above the line of the square pillars from archaic temples, which was at the castle while the architrave of the great temple derives from a temple dated to the Hellenistic period. Parts of the architraves of the temple (40 pieces) was used as a building material in the construction of the Venetian castle (see above). The columns and their foundations from buildings that were erected during the Hellenistic period, which has undergone various modifications and changes during the Byzantine period to be used for the large Christian church. When they built the temple used to ionic festoons from buildings that primarily had been built during the classical period. On the east wall, to the right of the temple, there is a marble slab inscribed with Lord Hari Serapis that probably comes from the island’s Serapeum. The altar was made of a large part of an archaic festoon and four columns dated to the Hellenistic period.
The Archaic Period
At Agios Nikolaos temples have been built in seven Doric capitals and two architrave taken from the temple of the archaic period.
After studies by Professor Gruben considered that an architectural complex used in the construction of a Byzantine church seems to have originated in ancient times. This consisted of a colonnade of Ionic order which shaped at least two corners and surrounding an interior space. The identification of other architectural elements such as structures, apse and the altar led to the hypothesis that the architectural elements belonging to Hestia and Prytaneions shrine. Two inscriptions which can be related to the temple of Hestia strengthens this view.
The baptistery is nine parts of the old architraves used as beams above the side once DEVICES columns. Other parts are built at the middle entrance of the baptistery, on the patio and in the Agios Nikolaos church. On the floor of the nave of the church of Panagia in front of the iconostasis, at 1, 50 meters are preserved two large Ionic columns with foundations built on top of a mosaic floor in high school from the 200-century AD Part of this mosaic floor where the great deeds of Hercules are depicted on display at the museum’s patio.
