An architectural freize is a horizontal band used as an adornment or embellishment in a facade or wall construction.
The photo below shows a tan color horizontal freeze at the national building museum in Washington DC.
This architectural freeze is is carved and sculpted to show to show a brigade of Union soldiers from the Civil War. Architectural freezes vary in levels of ornature and detail. Some architectural freizes just show simple designs such as geometric shapes.
The photo below shows an example of a historic brick masonry building with a terra cotta inset freize in a style of a Grecian key, possibly intended to symbolize strength and resiliance, where used in ancient Greek architecture.
