The cave extends some 50 metres (160 ft) into the cliff at the surface, and is about 150 metres (490 ft) deep, with a sandy bottom.

The cave as in every medieval history was said to be a refuge for devils and monsters. Two priests determined to drive them away entered the cave swimming, after a few minutes spent inside it they ran away in panic as if they had seen the face of the devil. From that moment on, the two began to rant.

The now-missing arms on the recovered Triton statue—usually depicted with a conch shell—suggest that the statues recovered in 1964 are the same statues Pliny the Elder saw in the 1st century AD. According to a reconstruction of how the Blue Grotto

At the back of the main cave of the Blue Grotto, three connecting passageways lead to the Sala dei Nomi, or "Room of Names", named for the graffiti signatures left by visitors over the centuries. Two more passages lead deeper into the cliffs on the side of island. It was thought that these passages

As light passes through the water into the cave, red reflections are filtered out and only blue light enters the cave. Objects placed in the water of the grotto famously appear silver. This is caused by tiny bubbles, which cover the outside of the object when they are placed underwater. The bubbles

The cave is 60 metres (200 ft) long and 25 metres (82 ft) wide. The entry is 2 metres (6 ft 7 in) wide and roughly 1 metre (3 ft 3 in) high at low tide, making safe access possible only when tides are low and the sea is calm. To enter the grotto, visitors must lie flat

In the case of the Blue Grotto, the light comes from two sources: the narrow arched entranceway, and a large hole somewhere below the above water entrance, separated by a band of rock between one and two meters tall. Because it is farther from the surface much less light passes through the lower

In part because of the dazzling effect of the light from the above-water opening, it is impossible for a visitor who is in one of the rowboats to identify the shape of the larger hole, the outline of the bar that separates the two holes, or the nature of the light source, other than a general

In 2011 a visitor suffered a life-altering injury when his neck was broken while entering the cave. The

The Blue Grotto is one of several sea caves worldwide that is flooded with a brilliant blue or emerald light. The quality and nature of the color in each is determined by its unique combination of depth, breadth,
