Blue grotto

From the outside, the cave looks like a 50-meter-long nose of a Tapir coming out of the cliff and then disappearing below sea level.

The Blue Grotto is located in a group of eight caves that have been created over the centuries. The water in the caves has a bottom of a white sandy colour. The sunlight is reflected and is broken down in different colours.

The water absorbs most of those colours, but not blue, which gives a beautiful light effect in the caves.

The colour of each cave is determined by the specific light in that cave.
Due to the angle at which the sunlight shines in the caves, the effect is most beautiful between 9 am and 1 pm and optimum at around 11 am.

The Blue Grotto is 60 meters long and 25 meters wide and has three interconnected passages at the end. In one of the passageways there are many signatures on the wall made by the visitors to the cave through the centuries.

In 27 AD the cave was used as the private swimming water of the Roman emperor Tiberius. Then the cave was decorated with statues and had resting areas.

In 1964 three statues of the Roman sea gods Neptune and Triton were found and in 2009 another seven statues were found. The suspicion is that there must certainly be four statues on the bottom of the cave.

In the village of Wied iż-Żurrieq you can take a trip in a small traditional fishing boat (Luzzu and Frejgatina) and view the cave.
