Edited sentence: According to school legend (probably promoted by the prefectorial board to scare new students during orientation programmes), this is because a grave was found at one end of the pool, making it impossible to build the full 50 metres.Also at this spookiest part of the school, which happens to be one of the most poorly lit places at night, there is a male and female toilet at the end of the corridor on 3 stories all on top of one another.But there are also many pupils who swear to it but not many people can actually prove it.However, few have actually bothered to measure the length of the pool.It is belived that students that walk along the corridor late in the night would see the head of a floating baby, which is belived to be the ghost of a baby foetus preserved in the Biology laboratories.Particularly the female toilet (during school hours it is a male toilet) at the ground level, there are numerous reports of ghost sightings.Probably due to the fact that the mirrors of the toilet are removed (which the school administration declines to explain), the pupils who are already stressed out by the sheer amount of work will tend to be overconscious of their surroundings and imagine things which are not there.The swimming pool is thought to be slightly short of being an Olympic-sized pool (at around 49 metres).There is one particularly potent haunting on the third floor of the Administration Block, in the corridor leading to the Biology laboratories
