in the medulla!
The renal columns are located in the renal medulla, which is the inner part of the kidney. They are extensions of the renal cortex that project into the renal medulla, helping to support and divide the structures within the kidney.
medulla
the medulla is organized into a GROUP of pyramids. It makes up the pyramids.
The Renal Cortex is the outer most layer of the kidney and while it contains many microscopic structures, it doesn't really contain any structures that can be seen by the naked eye. The Renal Medulla however contains many macroscopic structures such as veins and arteries, and most notable the renal pyramid, renal columns, minor calyx and major calyx.
The renal pyramids are located in the inner region of the kidney, known as the renal medulla. They are triangular-shaped structures that contain the nephrons responsible for filtering the blood and producing urine.

It is called the papilla.

Renal papilla. The renal papilla is the tip of each renal pyramid where urine is collected before being expelled into the minor calyx.
Renal pyramids are the cone shaped tissues in the kidney. The base of each pyramid starts at the corticomedullary border.
The ureter expands within the kidney to collect urine filtered by the neprhons. The renal pyramid is not made up of the ureter.
The Egyptian pyramids are ancient pyramid-shaped masonry structures located in Egypt.
