Oldřich Oak, Pedunculate oak in Peruc, Czech Republic

The Oldřich Oak is a solitary oak tree standing in the village of Peruc in the Czech Republic, reaching a height of about 95 feet (29 m). Its trunk is very wide at the base, and the lower branches extend outward in several directions, giving the tree a broad, rounded crown that stands well above everything around it.

The oak appears in the Chronicle of Dalimil, which ties it to Duke Oldřich's meeting with Božena; their son was Bretislaus I. Its age is debated: 500 years in 1872, 1,000 in 1910, and over 800 in 2009. Some experts think the legend was transferred to a younger tree.

The oak's name comes from the 11th-century legend of Duke Oldřich, who is said to have met the peasant girl Božena near a well in sight of the tree; their son was Bretislaus I. The story appears in the Chronicle of Dalimil, and the tree has since been treated in works by František Nepil, Miroslav Horníček, František Ženíšek and Adolf Liebscher.

The tree is easy to reach on foot from the center of Peruc and sits in an open spot with no special equipment or preparation needed. The ground near the trunk can be uneven, so sturdy shoes are a good idea.

The hollow trunk has been set on fire by vandals more than once, in 1993 and again on the night of 13–14 August 1995, and the oak survived both. Its condition was rated 2 in 1988 and 4 in 1998, and experts note it is slowly dying back.
