Interior navigation stands require no fasteners and leave the walls of the monument intact. White stands are for the state rooms of the museum that are filled with natural light. To the black stands in the wing “Ruin” we have added some muted and a bit mysterious light. The interior of the museum is made with various materials: marble, limestone; brick walls, old plaster and cast iron in the “Ruin”. Each material has its own special texture and provides new sensations. New stands correspond to the general level, their presence in the interior does not seem excessive, on the contrary, they perfectly complement the interior and the exhibits. The decision to use natural plywood is accented by milling the most important information.
