Welcome to the confusion we call BBQ.
The first pits were just holes in the ground, filled with logs burning to cook meat. Nt too long afterwards (after they were invented) concrete blocks were used to contain the fire. Use 'em if ya got 'em.
I bet there's someone with lots of information on building a concrete block pit somewhere 'round here.
