The image is a photograph of a sign on the side of a building that reads "The Renovation of Charlotteburg Palace". The sign is white with black text and a blue border. The text is written in German and appears to be a list of information about the renovation of the palace. 

The sign is located on a wooden surface and is located in front of a brick wall. The building is a two-story structure with a red roof and white walls. It has a large arched entrance and a balcony on the second floor. The entrance is flanked by two columns and there is a small garden in the center.

On the left side of the sign, there is an illustration of a castle with a blue sky and white clouds in the background. On the right side, there are several smaller illustrations of buildings and trees. The sign also mentions that the renovation will be carried out in sections of the building and that it will be able to remain open for further information, including special tours.
