In an era without 3C entertainment, the circus is one of the favorite pastime places for nobles. There are clowns performing stunts, musicians playing music, and animal trainers showing their talent of taming beasts.
This is a small circus. The shape is combined with the hull, as if it were in an amusement park. Because I want to showcase the detailed construction, I made it cross sectional.
The people in the audience are enjoying the happy performance. There were several booths around the building, including booths for playing small games, and stalls selling magic books and mysterious potion. People come here to watch performances and go shopping.
