Near the Grand Mosque, the Lalla Zninia Spring (also known as the Source Bleue) is touted as Tiznit's main sight. Until recently this did not bode well for Tiznit's tourism industry, as it was pretty much dried up and certainly not blue. The Tiznit authorities have plans to turn around the fortunes of the spring and major renovation works were underway in 2014. The spring honors the saint after whom Tiznit is named. There are several legends relating to this woman. One
has it that she was a shepherd girl who brought her flocks to this spot and smelled the then-undiscovered spring below; her sheep dug (if you can imagine sheep digging) until they found the water, and the town was born. Another story talks of a repentant prostitute who later became a saint. In any case, to catch a glimpse of her tomb on afternoons when devotees visit, follow the prison wall and turn left on the first narrow neighborhood street; the tomb is behind a green-painted door on your left.
