Petrohradský dub, Remarkable tree in Háj Petra Bezruče, Petrohrad, Czech Republic

Petrohradský dub is a summer oak at the edge of Háj Petra Bezruče near Petrohrad, with a trunk circumference of 900 cm (2001), a height of 27–28 m and a crown 20 m high and 19 m wide. Its hollow trunk forks at 8 m, and it stands on the left of the road to Stebno, about 280 m past the cemetery.

The oak is about 900 years old and is also called Selský dub or dub Petra Bezruče. According to legend, during the peasant uprising of 1680 the reeves of nineteen villages met beneath it and, after their defeat, predicted injustice would last as long as the tree stayed green. Háj Petra Bezruče was declared a natural monument on 15 September 1957, the poet's 90th birthday.

The oak is also called Selský dub (Peasant Oak) and Dub Petra Bezruče, after the poet whose name the surrounding grove bears; the grove was declared a natural monument on 15 September 1957, the poet's 90th birthday. A legend ties the tree to the peasant uprising of 1680, when reeves of nineteen villages met beneath it and, after their defeat, foretold that injustice would last as long as the oak stayed green.

The oak stands on the left side of the road from Petrohrad towards Stebno, about 280 m past the cemetery, with benches beside it. The trunk is hollow and forks at 8 m, so keep to the road and do not climb it. The granite bedrock of Háj Petra Bezruče brings boulders to the surface, some shaped like faces.

The oak's trunk is hollow and forks at a height of eight metres. Its girth reached 900 cm in 2001, surpassed among Czech memorial oaks only by Žižek's oak in Náměšť. Benches stand beside the tree on the road from Petrohrad towards Stebno, about 280 m past the cemetery.
