The apartments of Napoleon III are next in line. Leave Room N°501 by walking past the statue of Charlemagne towards the far end of the room. Pass through Rooms N°502-504 and enter Room N°505. Go to the centre of the room and turn left towards a monumental staircase. Go up until you see the landing and the entrance to the State Minister Apartments (Room N°553). Walk through Rooms N°553-550 and turn left. Walk along the long corridor until you see to your right the Dining Room N°548 and the Concert and Theatre Room (N°545). At the end of the aisle, you will arrive at the Grand Salon (N°544), the most impressive room.
