Starting off with something different we have a couple of 28mm Caravansary. These were like Ancient motels providing a safe haven for travellers and their animals all the way from Eastern Europe to China and proliferated along the Silk Road. They have been common from Ancient times to the modern era.
These are, as can be seen, nodular so can be enlarged with additional sections if required.
Figure are 28mm of various manufacture.
