Some people find visiting ordinary museums to be a bit dull. Fortunately for them, there are unusual museums to check out, such as underwater museums!

How can you visit and what can you see?

Many underwater museums are supported by companies that offer guided tours. A trained guide leads groups around a stunning underwater display of statues in each museum. Depending on the depth of the museum, visitors may be able to view the sculptures from a glass bottomed boat or by swimming on the surface. Other underwater museums are deeper and are most accessible to scuba divers.

Why are the museums underwater?

Underwater museums have many functions. One of their aims is to create a man-made reef environment where sea creatures can live. That’s why some of the museums are located in areas that were damaged by hurricanes or are considered underwater ‘‘deserts’’. The statues in the museum are designed in a way that encourages the growth of coal and plant life. Over time, the statues and plants attract a growing number of fish to the area.
