Oldest vine

The Old Vine, in Maribor, Slovenia, is nearly 400 years old.  A scientific measurement of the vine carried out in 1972 established that the vine was then at least 350 years old and may have been up to 400 years in age.  (It was impossible to establish a more precise age because the central plinth was rotten.)   An illustration from 1681 shows the vine, the grapes of which are ceremonially picked in October each year.  The vine has been declared a Slovene national monument.
