The last decades have been recorded turn in the urban policy that is followed for the growth of cities. The strategies of growth have been removed by the logic of continuous extensions and are directed henceforth in the care for their reformation. Thus are promoted programs of reformations in regions and spaces that have fallen in disuse or are abandoned (old industrial nutshells, camps, railway and harbour installations and other’s.  Last years the reformations that are realised in old harbour regions have constituted the most characteristic example of faculty of cities to be adapted in the new conditions. The spaces of old harbours are faced as places of planning of public space, which, renewed so much functional what aesthetically, offer the possibility for development of economic activity. The effort of re-establishment and reuse of installations did not stand always achieved, however practised big influence in a lot of parameters of picture of each city. Moreover it promoted the collaboration between private initiative and public schools or other governmental institutions.

 This inquiring work will be reported in regions where the cities relate itself immediately with their coastal line. The structure of many of such cities worldwide is connected closely with the aquatic foreheads that stood the cause for the foundation and their later growth. We will deal with cities famous for their coastal character, in our effort to search, to analyze and to evaluate their invigoration insofar as it were achieved in them the last years. Thessalonica, following the example of cities-harbour worldwide, enters in the process of transformation of old harbour in urban space. On the occasion the cultural capital (Thessalonica 1997) certain urban operations infiltrated in the harbour. The attribution of space of deposits in their jetties 1 and 2, in cultural uses, contributed in the arrival of visitors in the space of harbour. With this spark the make, developed progressively a new relation between the harbour and the city of Thessalonica. The continuous growth of urban web of city will lead some moment to impasse with the continuous extensions. For this reason are judged necessary the utilisation of urban voids, the recycling and reuse of the port, the exploitation and his appointment as an active and completely incorporated department of city. Below are presented the examples of three cities of - harbours of Mediterranean (Genoa, Barcelona, Marseille), what faced problems publics with Thessalonica. This cities present resemblances in the historical development of their ports and belong in the same area of influence with Thessalonica. The conditions that led to the desolation of harbour installations were similar. In this cities, for roughly two decades, were worked out programs of reformation of their aquatic forehead aiming the re-establishment of relation of city of - sea. It is considered advisable it is searched and is evaluated the way that these cities faced the situation that today faces Thessalonica. We can use the previous examples for developing a new plan achieving an integration of the port with Thessaloniki .
