A unique technical monument - a full metal, riveted observation tower at the top of Studenec (736.5 metres above sea level), erected in 1888. It is situated approx. 5 km to the north-east of Česká Kamenice, between the hamlets of Líska and Studený. There used to be a wooden observation tower on this site as early as in 1854 - 1865. Due to its bad technical condition it was pulled down in 1868. When a carriage road was made to the top of the Studence Hill in 1988, the Mountain Rescue for Czech Switzerland initiated the construction of a new metal observation tower. The construction lasted only three months and it was led by the builder Gustav Dittrich. The construction parts were made by Pražská strojírenská a.s. Ruston & Son following the latest technology and in accordance with modern construction trends. The iron edifice is 16.2 m high and it consists of subtle profiles connected with rivets. In the middle there is a spiral cast iron staircase with 92 steps and several resting places, and at the top there is an observation platform for 25 people maximum. After 1848 nobody was looking after the edifice. In 1995 the Amici Decini Society initiated negotiations about how to save the observation tower and on 28 March 1997 this second oldest metal observation tower was declared a national technical heritage site and became listed. This stopped the tower from being destroyed at the very last moment. After long and fairly complex negotiations, the town of Česká Kamenice with the support of the Citizens' Association of Studený and Lipnice started to repair this unique landmark in 2007. The metal construction of the observation tower was divided into three parts and taken off Studenec Hill by a helicopter. On 14 March 2009 the repaired parts were transported back by helicopter onto the peak and anchored in new foundation footings. 21 June 2009 the observation tower was officially opened to the public. The observation tower is open all year round and it offers beautiful views over the wide surroundings.
