Blatenský vrch, Mountain and observation tower in Potůčky, Czech Republic.

Blatenský vrch is a granite mountain reaching about 1,043 meters in the Ore Mountains, topped with a television tower and observation platform at its summit. The structure commands views of the surrounding landscape and serves as a key landmark for visitors exploring the region.

Tin and iron mining around the mountain led to the founding of the mining town of Horní Blatná in 1534. The winter sports club had a staffed hut built on the summit in 1906, and a hotel with a 21-metre lookout tower opened on 5 July 1913, named after Archduchess Zita. After 1945 the hotel fell into ruin and was demolished around 1970, leaving only the tower.

The tower's original name reflects the Austro-Hungarian period when the region was part of that empire. Today it draws visitors who appreciate both the views and the local connection to that historical identity.

The summit is about a 20-minute walk from Horní Blatná railway station on the Karlovy Vary–Johanngeorgenstadt line. A narrow access road branches off the Horní Blatná–Boží Dar road and runs about 1 km north to the top. From the red-marked junction Pod Blatenským vrchem the summit lies roughly 700 m to the northwest.

The 21-metre tower was named after Archduchess Zita of Austria when it opened on 5 July 1913. During the Second World War it served as an air-defence observation post for the Wehrmacht, and the adjoining hotel was demolished around 1970.
