Kokino is an ancient observatory located on a plateau in northern Macedonia. It is believed to be one of the oldest observatories in the world, dating back to the Bronze Age, around 1800 BCE.

The site was discovered in 2001 and has since been studied by archaeologists and astronomers. The observatory consists of a complex of stone circles and markers that were used to track the movement of the sun, moon, and stars. The markers were aligned with the solstices and equinoxes, and may have been used for religious and agricultural purposes.

One of the most remarkable features of Kokino is a stone throne that has been carved into the rock. The throne faces east, and is believed to have been used by a priest or astronomer to observe the rising sun on the summer solstice.

Kokino was added to the UNESCO World Heritage List in 2016, and is open to visitors who wish to explore the site and learn about its history and significance.
