A large part of the route takes place on the Mures Promenade and surrounding the Arad Fortress.
The Arad Fortress is one of the most important historical monuments existing at present in the west area of the country and it was built in the second half of the seventeenth century, being considered one of the most impressive military fortification of those times. Arad fortress was built in a Vauban -Tenaille style after the Austrian architect Philip Ferdinand Harsch’s plans at the request of Maria Theresa Empress having the shape of a star with six corners. The work lasted 20 years, with minor interruptions caused mainly by lack of manpower, so the fortress was completed in 1783.
After finishing working, various military units were placed in the fortress and thus Arad became a military-political centre of the Austrian domination in the area. History of the city in its more than 200 years of existence, is linked to important events. During Horea's Revolution in 1784, the city was one of the action centres of the imperial troops against the rebels. During the Napoleonic wars, many French prisoners were kept in the fortress. After the revolution from 1848, in the city pillboxes were imprisoned and condemned many revolutionaries including EftimiÔe Murgu. With the end of the nineteenth century, when the strategic concept had changed, the city lost its importance and became a simple barracks.
