The treetop trail in the Giant Mountains (Czech: Krkonoše) is the second experience trail created by eak (Erlebnis Akademie AG) in the Czech Republic.
Over a length of 4,922 ft, it twists through the treetops of the mixed mountain forest. It ends at a lookout tower with a height of around 141 ft, and its platform offers a breathtaking view over the Krkonoše National Park.
The St. Josef Church in Holzkirchen project comprises the main church and a chapel, which are connected by a common foyer with the sacristy. The foyer area and the sacristy were built as a reinforced concrete building. The main church and chapel are differently sized timber structures and take the form of inclined truncated cones with an elliptical footprint.
