How can I build a fire pit using bricks?

To build a fire pit using bricks, first choose a location away from flammable materials. Dig a circular pit about 2 feet deep and line the bottom with gravel for drainage. Arrange bricks in a circle to form the walls of the pit, stacking them securely. Fill any gaps with heat-resistant mortar. Finally, add a metal fire ring or grate to protect the bricks from direct heat.
