Interior

The interior of the building is covered by a sky lit gable roof supported by rafters at equal intervals, allowing sunlight to flood the Arcade. It was originally designed to stand only two stories tall, until 1827 when plans were altered to reduce the height of each story and add a third. The Arcade's space widens as it rises, allowing for a view of all concourses, and enabling each shop and office to be directly illuminated. The ground floor shop windows are slightly convex, like those of the Burlington Arcade in London. The second floor space, which widens by approximately 1.5 meters on each side, contains galleries with cast-iron railings that are connected by bridges in the middle of the structure, and on the ends before two fluted columns framing a view of the streets. The shops on the second floor are less deep than those on the ground floor, and have angularly projecting display areas. The third floor, like the second, is also set back on either side, but its gallery runs the entire length around the columns placed at each end. The windows of the shops and small offices originally housed on the third floor have small, narrow panes, a common feature of the time. The interior façade is crowned with a continuous cornice, at which the curving base of the glass-roof structure begins. A ridgepole with the inscription 1828 and the name of the arcade marks the structure's end.
