Velký a Malý Polom, Nature reserve in Horní Bradlo, Czech Republic.

Velký a Malý Polom are two separate parts of the Polom nature reserve in the forest complex southeast of Horní Bradlo, in the Chrudim district. They lie at 545–625 m and cover 20.24 ha, protecting fragments of fir-beech old-growth forest, spring ash woods and floodplain alder stands. Trunks of massive trees covered in mosses stand in the reserve.

Polom was declared a nature reserve in 1933 to protect the last preserved fragment of fir-beech old-growth forest on the ridge of the Železné hory. The protected area was enlarged in 1955 and again in 2011, when it reached its present extent. It is divided into two separate parts, Malý Polom and Velký Polom, together sometimes called Prales Polom.

The reserve is split into two separate parts, Malý Polom and Velký Polom, together sometimes called Prales Polom, "the Polom primeval forest". The protected area is managed by the AOPK ČR, specifically the Administration of the Železné hory Protected Landscape Area.

The reserve lies in the forest complex southeast of Horní Bradlo, in the Chrudim district, between 545 and 625 m above sea level. It has two separate parts, Malý Polom and Velký Polom, so plan your route between them in advance. The terrain is forested ridge with spring-fed ash and alder stands, so wear footwear suited to wet, uneven ground.

The reserve's two parts, Malý and Velký Polom, are sometimes called Prales Polom, "the Polom primeval forest". In the protected area stand the torsos of massive trees overgrown with various mosses, a detail to look for along the ridge of the Železné hory.
