The Ring of Fire by Matthew Ring, a dry stone fire pit

 
   
   
 
 
 

This 'ring of fire' was built by Matthew Ring in Guelph, Ontario, Canada using only stone, no cement. The star-burst roman arches allow air to fuel the flames. Mathew is credited as an inspiration to his peers by John Shaw-Rimmington, founder and president of Dry Stone Walling Across Canada.
