Bartek Oak
Świętokrzyskie
The Bartek Oak, located near Zagnańsk in the Świętokrzyskie Mountains of Poland, is among the country's oldest oak trees. Estimated to be around 686 years old as of 2016, the tree has an impressive height of approximately 28.5 to 33.5 meters and a massive girth exceeding 13 meters at its base. Its crown spreads widely, covering about 40 meters. Historically, it is linked with Polish royalty; legends say King Casimir III held court beneath it, and King Jan III Sobieski rested under its branches after the Battle of Vienna, even hiding a Turkish sabre and wine bottle within its hollow. Despite its age, the oak is still alive but in decline, with a thinning sapwood and a leaning trunk. Conservation efforts have included filling its hollow with resin and installing telescopic supports to sustain its heavy branches. The tree is protected as a natural monument and remains a symbol of Poland's natural heritage and resilience.

History
Bartek Oak's age was once estimated at up to 1200 years but modern ring count methods in 2016 established it to be approximately 686 years old.
In 1829, the oak had 14 main branches, but by 2008 only eight remained due to natural decline and damage.
The tree suffered fire damage in 1906 and was cemented in 1920 to protect its hollow trunk, a treatment later replaced by resin filling in the 1960s.
It was officially declared a natural monument in 1954 and has since undergone various preservation efforts, including lightning protection and structural supports.
In 2025, one of its southeastern branches broke during a storm, highlighting ongoing challenges in its conservation.

Main Trunk and Hollow1920s
The massive hollow trunk is a defining feature of Bartek Oak, historically filled with limestone in the 1920s and later replaced with resin to preserve the tree's structure. Visitors can observe the extensive hollow area that reflects the tree's age and resilience.
Crown and Branches
Bartek's crown spans approximately 40 meters, though the number of main branches has decreased from 14 in 1829 to 8 in recent decades due to natural aging and storm damage. Telescopic supports have been installed to help sustain the heavy branches.
Commemorative Stone1933
Located east of the oak, this stone was unveiled in 1933 to commemorate the 25th anniversary of the ZWC and Związek Strzelecki, local patriotic organizations. It was once overturned for over 30 years before being restored to its current position.
