Červený vrch, Summit in northern Czech Republic

Červený vrch, also called Stříbrník, is a hill in the České středohoří protected landscape area, 3 km north of Louny. Its red subsoil consists of porcelanites formed by the baking of clay from coal seams, and the hilltop holds the wooden Ejemova chata with the Frotzelova rozhledna lookout tower.

In 1910 the Louny branch of the Czech Tourist Club built the wooden Ejemova chata on the summit, with the Frotzelova rozhledna lookout opened on 4 June 1911. The hut was named after club chairman Josef Ejem and the tower after Louny doctor Josef Frotzel. In 1950 local authorities transferred the hut to the Dobroměřice collective farm; tourists only got it back in February 1991.

The wooden Ejemova chata on the summit, built in 1910 with the Frotzelova lookout tower, was opened on 4 June 1911 and named after Josef Ejem, chairman of the Louny branch of the Czech Tourist Club, and the Louny doctor Josef Frotzel. The club holds a New Year's ascent to Červený vrch, and the hut is otherwise open to the public from April to the end of October.

A red-marked circular local trail leads to the summit from road no. 28. The KČT hut on top, owned by the Louny Czech Tourist Club, is generally open to the public in the summer season from April to the end of October, except during special events such as the New Year's ascent to Červený vrch.

The red rock at the summit is porcelainite, formed when clay in coal seams was baked by underground fires; fossils of Tertiary organisms have been found in it. The hill is also called Stříbrník, after the silver mines once worked here.
