Marina proved helpful at the Hermitage as a guidebook. At the beginning of the invasion, the art work that were housed at the Hermitage was boxed up and shipped away. All the frames were left clinging empty for the walls. Even though a warfare was going on, Marina mentally made it through the deprivation of the siege by creating a memory palace in her mind in the art work that once strung the walls of the Hermitage. A memory building is a technique for memorizing many things. In order to employ this method, Riva walked through the museum many times, viewing unique places within it, in the same order each time. After having a few practice of this, one should be able to bear in mind and imagine each of the places in order dependably. This concept was taught to Marina by Anya, among the babushka's that worked in the museum. Marina created a storage palace within herself, keeping in mind things by placing them virtually around a structure. Marina thought a place in her brain with lots of rooms, and equipped the bedrooms in her memory with whatever she wanted to remember (art work). She psychologically placed absent paintings into their structures, memorizing and imagining the appearance and location of each and every piece that once put up the walls from the Hermitage. This task helped Riva discover how to maintain the treasured art the girl loved and cherished in her memory. She sooner or later remembered the placement of every piece of art in the collection, building a recollection palace, to get herself and future generations. The memory space palace was obviously a personal map in her mind, that only she may see, that remained brilliant in her thoughts through the remainder of her life.
