The image displays an archaeological exhibition or partial reconstruction of a Roman hypocaust system in Perl, Germany. The scene is an overhead view into a rectangular pit. Within the pit, numerous stacks of reddish-brown square bricks, known as pilae, rest on a light brown earthen floor. These stacks vary from single bricks to six bricks high, arranged throughout the space. A semicircular archway constructed of reddish-brown bricks is centered at the rear of the pit, opening into a darker recess. The pit's perimeter is defined by a raised border of reddish-brown terracotta elements. The surrounding wall's lower section comprises rough-hewn stone masonry. Above this, a painted frieze displays a dark ground, featuring alternating reddish-brown rectangular panels with golden outlines and internal 'X' designs, separated by green, stylized leaf motifs. A dark brown band horizontally separates the painted section from the stone. The adjacent floor surface is a light, speckled aggregate material. A segment of a black metal chain is visible in the lower right corner. No individuals are present in the scene.
