Aged trees are considered as a valuable source of information on the past ecological conditions and social life where they are found, and their documentation and preservation are vital for the continuity of benefits they provide. Nineteen Castanea sativa Mill. individuals on abandoned agricultural plots near Artvin city center (Turkey) were measured for diameter at breast height (DBH), circumference at breast height (CBH) and height. DBH and CBH ranged between 72 cm and 186 cm, and between 231 cm and 615 cm, respectively. The highest tree is 22.20 m tall and the shortest is 13.65 m. Estimated ages of the trees ranged from 135 to 342 years. With their size and age, these trees can be designated as monumental trees. Protection of these trees will help in conserving C. sativa genetic resources and in passing the information they hold in their annual rings to future generations
