The island of Tinos is famous for the many intricately designed dovecotes found here. They are fortress like stone structures with two levels of which the lower level is usually used to store utensils and other items. It is decorated with both geometric patterns including triangles and rhomboids and non-geometric patterns including cypress trees and variations of the sun. It is believed that these elaborate patterns are the reason why the pigeons are attracted to these dovecotes. Most of these structures are found in the eastern and central parts of Tinos and the oldest ones are believed to be from the 18th and the 19th Century. It was the Venetians who first started a systematic breeding of pigeons after discovering that their meat was excellent tasting and that pigeon droppings are made for some high quality manure.
