The back end of the camposanto is a wall filled with niches. During the colonial era, families of stature are interred here while the general public were buried at the grounds. The material used is not only limestone blocks but also bricks which form the frame of the niche as well as at the top portion of the columns. The capital are tuscan but some are already missing.
Like in other camposantos, these niches are rented out for a couple of years. If the rent is not renewed after the period, the bones are dumped in an osorio, a common skeletal dumping ground found within the area.
