The main challenge that we are addressing is “To get more visitors to world Cultural heritage costal sites that covers a large area and is situated in the Southern Baltic Sea area”. All UNESCO world heritage sites, or similar sites, in the southern Baltic Sea area faces similar problems that can be jointly solved more efficient if put into a transnational context. Existing common problems are for example lack of knowledge about the sites, information and marketing of the sites, make them more available also for disabled by developing ICT solutions, different - not coherent regulations and conflict between conservation and development interests (tourism). We will contribute to the objective In the South Baltic Programme 2014-2020 measure 2.1 by:• developing cross-border strategies for preservation and use of the costal heritage sites, • by small-scale pilot investments and by creating sustainable tourism products through the development of technical innovations like applications and web solutions, but also to make it possible for disabled to visit and experience the sites by innovative physical and digital installations.• joint promoting and campaigns by creating information centres and /or increase the marketing of the sites in the existing tourist information centres • dissemination of good practice such as “Instagram event”, geocaching and successful events to make the sites more interesting• sharing expertise and developing joint recommendations on how to combine into one coherent planning system three different aspects: national statutory spatial planning regulations, particularly, if it is a protected area, UNESCO planning requirements for the world heritage sites and the EU protected area management regulations under the Bird and Habitat directives (and maybe MSP regulations, since all our target areas are the coastal ones).• meetings between those working with conservation and those with tourism development to get a balanced situation. Expected Results: The anticipated changes and the result/output after the completion of the project are:• More visitors to the sites due to:1) More information in tourist information centres etc2) Technical solutions (applications and web solutions) that improves the experience of the sites3) New solutions (also ICT based) that makes it possible for disabled people to visit and experience the sites 4) The conflict between conservation and development has decreased and this makes it possible to develop the sites and attract more visitors 5) More coherent regulations makes it possible to attract more visitors. Some of the main activities could be: 1) Work with the understanding of world heritage by the creation of an information centre for the site, or promote the sites better through existing tourist information centres, 2) Develop technical innovations like applications and web solutions to make the site more available, 3) Develop “Instagram event” in a Baltic Sea context,. 4) Develop and refine existing and newactivities into sustainable tourism products, 5) Use Geocaching to market and make the world heritage more interesting, 6) Sharing expertise and developing joint recommendations on how to combine into one coherent planning system three different aspects: national statutory spatial planning regulations, particularly, if it is a protected area, UNESCO planning requirements for the world heritage sites and the EU protected area management regulations under the Bird and Habitat directives (and maybe MSP regulations, since all our target areas are the coastal ones). 7) Meetings between those working with conservation and those with tourism (development) interest to get a balanced situation. 8) Sharing knowledge and best practices horizontally in the project.
