Poledník, Mountain summit in Prášily, Czechia

Poledník is a rounded, elongated ridge on the Kvilda plains of the Šumava, reaching 1,315 m, the fifteenth-highest summit in the Czech part of the range. Its steep eastern slopes were reshaped by glacial action and hold the cirque of Prášilské jezero and the dry cirque Stará jímka. The summit carries a 37-metre tower with three semicircular upper floors.

From the Iron Curtain onward the summit lay in a closed military zone of the Dobrá Voda training area. In the late 1960s the Czechoslovak army built a secret signals-intelligence facility codenamed TOPAS here, watching radio traffic far into West Germany. After 1989 it decayed; the national park administration bought it in 1997, demolished the buildings, kept the tower and opened it in July 1998.

The name Poledník means "noon mountain", also called Polední hora in Czech and Mittagsberg in German. Since 1998 the tower has housed a small museum on its history, especially its military use, and a snack hut stands beside it.

Visitors can reach the summit by following marked trails from Prášily or surrounding areas without special equipment. Most people take a few hours to complete the hike, and the route is accessible during spring through autumn when weather conditions are most stable.

The tower's three semicircular upper floors are the surviving shell of the Cold War listening post TOPAS, built in the 1960s to intercept radio traffic far inside West Germany. The site was so secret it often appeared on no maps, and nearby Prášilské jezero was off-limits. A small museum inside covers this military past.
