The isle of Tinos is dotted with these intricate constructions, known as peristerona (meaning “pigeon house”). Adorned with elaborate geometrical patterns to attract pigeons, the oldest of these structures are believed to be from the 18th and 19th century. The Venetians first started the breeding of pigeons for their meat but also because the pigeon droppings made for some good quality manure. The exact number of peristerona on Tinos is unknown, but it is believed to be in the hundreds.
