Vráteň, Volcanic summit in Kokořínsko Protected Landscape Area, Czech Republic.

Wratner Berg is a neovolcanic hill of 507 m, the highest point of the Mělník district and of the Housecká vrchovina, in the Kokořínsko – Máchův kraj protected landscape area. Its summit carries a three-sided sheeted steel tower 40 m tall, with a viewing platform at 25 m, opened on 28 October 1999.

A wooden tower was built on the summit in 1893 for fire brigade surveillance and stood until strong winds destroyed it in 1916. The steel tower that stands today was constructed later to replace the damaged structure and provide improved access to the views.

The name Vrátenská hora is linked to the nearby village of Vráteň (Libovice cadastre); German sources call the hill Wratener Berg. The 40-metre tower, opened on 28 October 1999, also carries mobile-phone antennas for Eurotel and Radiomobil, so the viewing platform shares the structure with telecommunications equipment.

Cars can drive to a car park in one of the former quarries on the south-west slope, then continue on foot to the tower or the summit. The tower stands on the blue hiking trail between Nosálov and Houska, and a short yellow-marked link path crosses the northern slope. Entry to the viewing platform is charged.

On clear days, visitors from the observation deck can spot multiple castles and mountain ranges simultaneously, including Bezděz Castle and Houska Castle in different directions. These distant views help hikers understand their position within the larger landscape and plan their journeys.
