Szukana fraza: [Abstract = "Many port cities in Europe and America face the problem of finding new uses for old, unused wharves. Sometimes they are adapted for the purpose of storage, sometimes they are used as car parks. An interesting example of turning the old waterfront into on the park comes from Philadelphia. The project, which began in 2009 is considered as innovative and of great importance for the revitalization of Philadelphian waterfront."]
