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 that which they are typically associated with.
