In older times, the island received frequent attacks by pirates, but also the Turks, the Franks, and the Venetians (in line with most other islands in the Aegean Sea). In order for the inhabitants to protect themselves from the attacks, they built the Medieval Castle, which is preserved in great condition to this day. The initial settlement was inside the Castle, but with the increase of the population it spread outside it.
Like in the rest of the Cyclades islands, the houses have many elements of Cycladic architecture (white houses, colourful doors and windows)
Despite its small size, Kimolos has a large amount of churches, some smaller, some larger, most of them being “private”. Eight churches located at the outskirts of the town are considered to be monuments of particular archaeological and historical value and are protected by the Ministry of Culture.
These are: The Birth of Christ, Chrysostomos, Virgin Mary of Konomos, Taxiarches (The Archangels), Pantokratoras (The Almighty), Sotira (Saviour), Agioi Anargyri (Saints Anargyri), Chrysopigi.
