Looking at the box it's clearly intended for the wargames market and by extension military modellers seeking a suitable diorama for figures and vehicles. To my eyes it looks distinctly North African and could probably serve as a non specific Mediterranean structure of some age. If built to the instructions it has a good sized 220mm x 180mm footprint, but viewed as raw material there are 1280mm worth of nicely moulded rough-rendered stone walls as well as a cobbled courtyard surface, two sets of stairs, a dome and some paving.
Stay tuned to see what becomes of this.
