This project utilizes ICT for the provision of useful services for cultural heritage tourists. The main goal is the creation of a digital repository of cultural and religious artifacts and the design and provision of mobile applications and services for citizens with religious interests and for religious heritage tourists in the cross border area of Kilkis and Krusevo. In the area of Kilkis there are traditional buildings with architectural characteristics of the wider region. These traditional buildings, with some morphological differences, exist in most Balkan countries. Similarly, in Krusevo there are houses of traditional architecture built in the late 18th and throughout the 19th century which show strong similarities to those of the area of Kilkis. The cooperation of the partners will highlight the common architectural and religious identity and the rich cultural and religious resources in the area. PROMO.CROSS envisages a set of innovative actions for the preservation and promotion of traditional architecture in the eligible area and the promotion of religious tourism. Such actions include the collection, documentation, digitization and 3D modeling of religious monuments and traditional architectural buildings in the cross border area, as well as the implementation of a business plan for the joint valorization of the architectural heritage.
