The area of Kria Vrisy in North Evia is a unique landscape shaped by Almyros river. Almyros river is 1,6 Km in length and comes from a place named "Mati" from where the river drained underground. The altitude of the source named “Mati” is very close to sea level and the river has steady and laminar flow throughout the year. Therefore the river mouth is used for the anchorage of small boats. The depth of the river is not greater than 1,5 m, therefore being sufficient for the safe anchorage of small boats The river has a very small water basin and with some infrastructures in the river mouth and there is the possibility of developing a tourist attraction riverside village. Therefore there could be established a thematic park of interest in the bank of the river which could have the "character" of a small Venice. The emphasis on character of the architectural-Infrastructures specifications which are planed to be built on the banks and the careful selection of the type of boat to be placed in the river, would lead to a sustainable development of this specific-profile unique tourist landscape. This paper presents this unique landscape, the principles to implement this project by the study of the landscape, architectural design which is compatible with the character of the site, and a brief summary of environmental assessment study.
