The museum is the place where all the mysterious pieces that man has worked to discover and understand are collected. The word mystery is often associated with the unknown, and the unknown means the unknown and incomprehensible For example, caves in nature are unknown, so knowing the entrance and not knowing what is inside them or knowing their exit has created a kind of mystery and curiosity to explore them. Also, considering that 80% of them are undiscovered and unknown, the seas and oceans are unknown and mysterious In the architectural idea, caves located in the mountains and oceans will be combined to indicate the existence of a mysterious and unknown world below and above the oceans.
