The park is divided into different areas, whose borders were developed by looking at existing conditions (such as how the site had been divided by existing roads and railways, what types of plants had begun to grow in each area, etc.). This piecemeal pattern was then woven together by a series of walkways and waterways, which were placed according to the old railway and sewer systems. While each piece retains its character, it also creates a dialogue with the site surrounding it. Within the main complex, Latz emphasized specific programmatic elements: the concrete bunkers create a space for a series of intimate gardens, old gas tanks have become pools for scuba divers, concrete walls are used by rock climbers, an area of the factory, the middle of the former steel mill, had been made into a
piazza. Each of these spaces uses elements to allow for a specific reading of time. The site was designed with the idea that a grandfather, who might have worked at the plant, could walk with his grandchildren, explaining what he used to do and what the machinery had been used for. At Landschaftspark, memory was central to the design. Various authors have addressed the ways in which memory can inform the visitor of a site, a concept that became prevalent during
Postmodernism.
Importance of memory Memory has re-emerged as an important aspect of design, and has been addressed by authors such as
Sebastien Marot,
Frances Yates,
Robert Smithson, and Peter Latz himself. For them, memory does not equal preservation but instead has a transient quality. It implies a re-representation or understanding of the past, as memories constantly shift and change as one experiences life. Marot believes that the memory of a site should be used as a design strategy, as it shows depth and a process of connection. Yates’ argument for the importance of memory comes out of her concern that architecture has become too uniform, removing the particularities of a place. These idiosyncrasies have a history with the
art of memory which uses the principle of association with places. Smithson's assertion, in his article "A Tour of the Monuments of Passaic," is similar, in that memory recalls the past but in a way that applies it to new things. Finally, Latz claims that interrelations must be made concrete and visible and that the viewer will create their own picture of a place, not the designer (Latz, 94, 96). These ideas of memory encompass Landschaftspark. A series of pathways at multiple levels connect sites scattered throughout the project, allowing visitors to construct their own experiences. These sites include the bunker gardens, where the
fern garden is located. This garden was formed using railroad ties collected from other locations at the site, which might remind someone of the old railway that is now an entrance to the park. It is similar to the way Smithson's essay, "A Tour of the Monuments of Passaic," incorporates elements of the past to aid in giving meaning to things of the present (Marot, 42). By walking through the garden, an individual's memory may be sparked when they see the typical railway ties. This might then reveal new connections, as these railway ties occupy a different space than the long lines with which they are typically associated. The sewage canal, which was believed to be in the same location as the ‘Old Emscher’ river, could not remain as it existed on the site, and was placed underground (Diedrich, 73). A new canal has taken the place of the sewage canal, but is now flowing with fresh rainwater. Instead of creating a more "naturally" shaped waterway, this new canal, the
Emscher River, was kept as straight as the canal before. The canal aids in one's understanding of water processes and changes in time. Markers made by soil mounds (these also break up the culvert form) allow the depth of the water to be read by the visitor to the site. Here the visitor is able to understand on a seasonal basis the process of the site and mark their experience of the park by how high the water was. Finally, Piazza Metallica also works with ideas of temporality and memory: the landscape architects took 49 steel plates that formerly lined the foundry pits at the site (Diedrich, 70) and installed them to mark a gathering place, intended for events and performances. However, the steel plates are not meant to last; rather, they will gradually erode and decay, portraying the natural processes occurring in the site (Steinglass, 129). In a way, this piazza represents the site as a whole: as the plates decay (like the other steel on the site), a succession of plants will grow between them. Plants will eventually fill the space, with the remains of the rusted steel among them. ==Comparing between landscape architects ==
