ornate ceiling of a rotunda

ornate ceiling of a rotunda. The ceiling is primarily white and features a repeating pattern of square coffers, each containing a decorative floral motif. The coffers radiate outward from a central, circular painting. The painting features a blue background with clouds, and a red, boat-shaped object in the center. The rotunda appears to be part of an interior architectural structure. The curvature of the ceiling and the presence of a partial archway on the right side of the image suggest it is a part of the State Historical Museum, located in Moscow, Russia.
