The \'Mura Region\' brand, to be introduced in 53 settlements in the border region in Hungary and for Međimurje County in Croatia, aims at assessing the tourism attraction inventory of the project area, furthermore at designing and developing its tourism image and philosophy, together with the preparation of its own quality assurance system. The development of the cross-border tourism brand contains a unified image, the identification of destinations and the joint presentation of the cross-border tourism region in both countries, e.g. at large scale tourism fairs Achievements: The construction of a wastewater treatment plant on the Croatian side and the reconstruction of an existing one on the Hungarian side set the common ground for joint environmental protection in the border area. The applied technological solutions significantly decreased the pollution of the river Mura and contribute to the preservation of the unique river landscape, as well as of the quality of groundwater in the area of the border municipalities of Podturen, Tótszerdahely, Becsehely and Tótszentmárton.
