The aim of the project is to increase the number of visitors in the border regions of Lithuania and Latvia by using the World War I heritage sites located in Augšdaugavas and Zarasai districts, which are relatively well-preserved on both sides of the border. During World War I, the German army created a unique fortification system that has survived for over a hundred years and is interesting for tourists. The international route is expected to include over one hundred different artifacts and places (dugouts, building and power station remains, shelters, hospitals, soldiers' cemeteries, narrow gauge remains, remain of aerodrome all these artifacts would be extremely attractive for visitors. Infrastructure built by German army brings these regions together with a defense frontline. Without the co-operation of both sides, the heritage of the First World War will not have the same momentum as by uniting and creating a common international route. One of the main tasks of the project is to create a strong e-marketing campaign which will introduce the public with created international route and the First World War exhibition in territory of Lithuania and Latvia. The goal of the project is to increase the number of potential visitors. The World War I expositions in Turmantas (Lithuania) and Medumi (Latvia) will be created within the project. Two info trips for media and tourism professionals will be organized. A website, a mobile application will be created and will be promoted. As the route will be positioned as a car-free route, 20 bicycles (10 for each of Partners) will be purchased for visitors. Each of the exhibition centers will also have 5 electro bicycles suitable for people with different levels of physical state. For convenience of visitors brochures with maps will be created in several languages (LT, LV, RUS, ENG, GER and PL). Trainings for guides will be organized that will provide new job opportunities for local residents. Conference for local residents and potential service providers will be organized to present the project and opportunities from increased tourists flow. A comprehensive research that will investigate The World War I legacy with the purpose to locate artifacts in the territory of Latvia and Lithuania will be carried out. This information will be used as a basis for information stands, guide’s presentation and website content. The sites and surrounding area will be improved by clean up activities and infrustructure, like information stands, road signs and waste bins.
