If a bonfire is necessary, how should a place be prepared for it?

In the clearing we clear a place for a fire, from grass debris and dry branches. You can overlay the place with bricks or stones, and clear the ground around them, where there will be no fire, you can also dig a small depression where you will put brushwood! This is done because it is dangerous to make a fire on the ground covered with dry grass in order to avoid fire! It is also dangerous to light a fire under trees or bushes!
