Answer:
Haha great question!
Step-by-step explanation:
My ideal entrance hall for a museum would probably have to be harry potter inspired. The Hogwarts castle is just such an amazing place it would be hard not to turn its architecture into a wonderful museum.
The entrance hall would have an arched ceiling with detailed wooden carvings and different shades of brown, e.g mahogany.
The floor would have a marble texture but it would be an illusion created with wood. There would be no glass windows, only torches. This gives it a very rustic theme and feel.
