From this position, one can see the service corridor located behind the façade of the Imperial Palace. Extending to the east of this corridor, on ground-floor level, is an intricate series of service rooms that presumably replicated the first-storey arrangement; the circular base of a bread oven, probably from the modern era, survives in one of these rooms. In the building’s ground floor there is also a large, vaulted cistern, with two pillars inside. At the eastern end of the complex, the rooms surround a peristyle, providing light through first-storey hopper windows.
