For more than a century the Ponale road has enchanted travellers. This route is ideal for all those who want to enjoy a nice cycling trip and a breath-taking view over Lake Garda and the surrounding mountains.
<p>The road overlooks the northernmost part of Lake Garda and the lower Sarca. Mount Brione, between Riva and Torbole, and Mount Baldo can be seen in the distance. The vegetation is sparse and Mediterranean. It consists of cypresses and holm oaks that manage to grow through the rocks.</p>
<p>The Ponale road was paramount to hold Riva and the North Garda Lake, then at the border between the Austro-Hungarian Empire (to which Trentino belonged) and the Kingdom of Italy. Because of its strategical value to Austria-Hungary, it was at the centre of an extensive network of fortifications since 1860. </p>
<p>Fort Teodosio dates back to this period. It owes its name to the finding of some coins from the reign of Emperor Theodosius. The fort was built to close off the road to those coming from Ledro. The port of Riva was defended by the Bellavista battery (or della Madonnina), just a few metres above the lake. The fortifications stopped Garibaldi from invading Trentino through Riva and forced him to go through the Giudicarie and Ledro.</p>
<p> The construction of the Tagliata (barrier) del Ponale began in 1904. It was part of a defensive plan put in action by the Austro-Hungarian Army in the whole of Trentino. The Tagliata is a network of tunnels and passageways excavated in the rock. It starts at the height of the seventh tunnel coming up from Riva (150 m / 500 ft) and reaches down to the lake. From the road, embrasures and doors can still be seen. The Tagliata guaranteed Austria-Hungary the control of Riva throughout the First World War. Excavations did not stop until 1918.</p>
