Generate for me a description of a magnificent scene inside a mansion with an arch, marble floor, and oil lamps.

As visitors enter the chateau through this enormous circular foyer, their first view is of sweeping dual stairways that lead upward in elegant curves to a gold marble balcony. Through a dreamstone-inlaid arch to the west, between and beyond the stairways, is a lofty Great Hall lined with fluted marble columns. Reddish light from a score of oil lamps creates a glow that warms the sky blue marble floor.
