The relationship between port and city has transformed many times in conjunction to the political, social and economical conditions. Docks are special port components, as artificial volumes that enter the sea. Due to their position, form and importance, they are a favoured issue of controversy. It is worthwhile to investigate the prospects of transforming docks into an active part of the city.
Docks were always links of communication between cities and the rest of the world. Their operation was upgraded due to technological advancement and the industrial revolution. Thus, modern docks were constructed. The use of containers for sea transport of products after 1950, resulted in removing the old commercial ports and abandoning their docks. A trend of regenerating these areas was noted around the '80s. The implemented strategies vary according to the set goals, which included economical growth (London Docklands), issuing the residential problem (Eastern Docklands), tourism, creation of public space, commercial growth, environmental improvement. There were cases where the wanted connection to the city was not accomplished (Melbourne Docklands). In Greece, the cases of docks' regeneration are of small scale and without a central goal. Nevertheless, it is an issue of study due to the importance of port for the Greek city. There are proposals for the port of Piraeus, Thessaloniki, Volos and Patra.
Critical factors for the regeneration of a dock that scopes to make it part of the city are combination of usages, economical and social capacity, re-establishing the relationship between man and sea, hypertopicality, avoidance of embellished and painless proposals, priority on the problems of each region and the people's necessities. Based on these, along with requesting the preferences of Volos residents, the removal of the commercial port and the refurbishment of the Silo's dock into a public green space of leisure are proposed.
