It is more than 90 years since a young boy named Cornelius Warmerdam started pole vault at home on the site in Hanford, California.
He used a tree branch as a pole and landed in a mound of earth.
Jumped with bamboo pole
Warmerdam would eventually dominate pole vault in the world for many years.
He jumped with a bamboo pole and he improved the world record by 23 centimeters to 4.77.
He was completely superior for a long time and it was not until 1957 - when metal rods began to be used - that his record was broken.
Warmerdam never got the chance to win any major international titles.
World War II raged during his career and the 1940 and 1944 Olympics were canceled and the World Athletics Championships did not yet exist.
Promising 19-year-old from the Soviet Union
The first World Cup was held in 1983. The venue was Helsinki.
A promising 19-year-old from the Soviet Union named Sergei Bubka came to the pole vault competition.
He went home with the gold medal - he would do so in another five straight World Cups, the last in 1997!
During his career, he set world records 35 times, when separate records were set indoors and outdoors.
He raised the record by an unimaginably 32 centimeters - from 5.83 to 6.15.
His eyes watered
Now his record is history.
When Armand Duplantis in a wonderfully timed jump sailed over 6.15 in Rome yesterday, it was such a beautiful sight that his eyes watered.
The highest jump ever outdoors seemed to be the simplest thing in the world.
This is what it looks like when virtuosos appear!
History's foremost pole vaulter is still named Sergej Bubka but Armand Duplantis seems to have everything it takes to eventually take over.
New breathtaking levels
He has many years to win the big titles required.
And as he jumps, he looks set to move the world record to new breathtaking levels - just as his predecessors Warmerdam and Bubka did.
And just like for Warmerdam in the 1920s, it was at home on the site that it all began.
