Most of the fountain seems to be constructed of composite to look like slate, with the 'natural stone' being the small rocks in the bottom. It is VERY heavy, so it should not fall over if backed up against a wall. Unfortunately there is no on/off switch so it needs to be unplugged and it uses 2 outlets; one for pump, one for light. we put it up on a bench outside and it looks nice. Much quieter than we though.
