REMEMBERING THE AZURE WINDOW IN DWEJRA, GOZO

The Grandma, Tina, Joseph and Claire in Dwejra
The Azure Window is a natural arch in Dwejra Bay, Gozo. Nowadays, the Azure Window is impossible to visit because it collapsed in March, 2017.  

Claire Fontaine, Joseph de Ca'th Lon, Tina Picotes and The Grandma have visited Malta several times and they could visit and see this wonderful arch before collapsing. Today, they have visited Dwejra Bay to contemplate the views without the arch and to remember together how it was. They have joined past photos to evocate this wonderful creation of Nature.

The Azure Window, in Maltese it-Tieqa Żerqa, also known as the Dwejra Window or  it-Tieqa tad-Dwejra, was a 28-metre-tall natural arch in Gozo.

Old Grandma's memories in Dwejra
The limestone feature, which was located in Dwejra Bay close to the Inland Sea and Fungus Rock, was one of the island's major tourist attractions until it collapsed in stormy weather on 8 March 2017. 

The arch, together with other natural features in the area, has appeared in a number of international films and media productions. The arch, which consisted of a rock pillar rising joined to the cliff by a horizontal slab, was created by the collapse of a sea cave, probably during the 19th century. The final collapse followed a century of successive erosion, in which large sections of the limestone arch had broken off and fallen into the sea.

The Azure Window developed through sea erosion of a cliff face. The progress starts with an initial notch resulting from wave action. This space devoid of rock then causes tensile stresses that lead to the formation of a vertical joint extending upwards from the notch. This joint would progressively become wider, first forming a cave and eventually an arch. 

Old Joseph's memories in Dwejra
The end of the lifecycle of the arch is reached when erosion finally progressed so far that the roof of the arch gets heavier than the pillars can support. It is not known exactly when the arch came to being, but the entire process is believed to have taken around 500 years.

The arch is not mentioned in 17th- and 18th-century descriptions of the Dwejra area, which was already famous due to the nearby Fungus Rock, so it probably did not exist then.

Giovanni Francesco Abela's 1647 book Della Descrizione di Malta and De Soldanis' 1746 manuscript Il Gozo Antico-Moderno e Sacro-Profano both mention a Tieqa Żerqa, written archaically as Tieka Szerka, or Għar iż-Żerqa, but this referred to the cave entrance to the nearby Inland Sea. It is likely that when the Azure Window formed it inherited its name from this other cave.

Old Grandma and Claire's memories in Dwejra
The earliest known record of the Azure Window is in an 1824 illustration of the nearby Dwejra Tower

However, it is shown in the background of the image, and it is unclear whether it was still a cave or if it had already developed into an arch. 

In 1866, artist Edward Lear visited Dwejra and stated in his journal that the coast scenery is not nearly as fine as that of Malta, suggesting that the arch did not exist. The earliest recorded photographs of the natural arch were probably taken by Richard Ellis, and they are found in an album belonging to Michael Dundon dated 26 July 1879. This means that the window might have formed sometime between 1866 and 1879. The photo by Ellis was published in a book in 2011, showing contrasting difference with 20th and 21st century photos.

Throughout the 20th and early 21st centuries, the arch was one of Malta's main tourist landmarks, and it was a popular backdrop in photographs. It was included in a Special Area of Conservation, and in 1998, included on Malta's tentative list of UNESCO World Heritage Sites, along with the rest of Dwejra Bay.

Old Claire's memories in Dwejra
Between the 1980s and the 2000s, parts of the top slab of the arch collapsed, significantly widening the arch. A large slab of rock on the outer edge of the cavity collapsed in April 2012, further increasing the size of the window. Another rock fall occurred in March 2013. 

Four months later a geological and geotechnical report was prepared by consultant Peter Gatt, who represented local firm Geoscience Consulting Ltd, and it determined that the arch was relatively stable and will continue to remain so for a number of years, and that there was no imminent risk of collapse, although it warned that rock falls will continue and it might be hazardous for people to go close to the arch.

Further rock falls and fissures were reported in subsequent years. Fishermen avoided going near the arch with their boats, and warning signs were put up to discourage people from walking on top. However, many people still went on the arch on a regular basis, and videos were uploaded on YouTube of people cliff diving from the window as rocks were falling down.

In March 2016, Gatt warned that the illegal use of explosives at the nearby Inland Sea could have an effect on the already weak structure of the nearby Azure Window

These comments were made in the wake of an investigation by the Malta Environment and Planning Authority which revealed that explosive material was probably used to do rock cutting in the tunnel leading to the Inland Sea. It was suspected that the illegal cutting was aimed at widening the entrance to allow larger boats to sail through.

In December 2016, an emergency order was published prohibiting people from going on the arch. However, this law was not enforced, and visitors were still walking on top of the arch days before it collapsed in March 2017.

The arch collapsed at about 9:40 am local time on 8 March 2017 after a period of heavy storms, leaving nothing visible above the water.The pillar gave way first, causing the top part of the arch to collapse along with it. 

Old Tina's memories in Dwejra
The pillar shattered into large chunks of rock as it collapsed. The collapse was said to have been inevitable. The collapse was reported in both local and international media. The Environment and Resources Authority called the collapse a major loss to Malta's natural heritage. The Church's Environment Commission said that the collapse should make the Maltese people reflect on their national heritage. The San Lawrenz local council urged the government to establish a management plan for the entire Dwejra area, which includes several other notable features despite the loss of the Azure Window.

On the day of the collapse, police appealed to the public not to visit the area. Diving in the area was temporarily banned, although this was not enforced and footage of the remains of the arch underwater emerged a few days after the collapse. The remains of the arch have formed a number of features which have been called a divers' paradise, although it is still advised to keep away from the area until surveys and inspections are carried out.

On 9 March, the government announced that it would launch an international initiative on the future of Dwejra

The options being considered include leaving the site as is, retrieving the remains of the window from the seabed and exhibiting them, creating an artificial or an augmented reality reconstruction of the window, establishing an interpretation centre or creating an art installation at the site. The government stated that the rock formation will not be rebuilt.

The Azure Window was a natural arch with a height of about 28 m and a span of around 25 m. It was at the tip of a headland known as Dwejra Point. The arch was found within the Lower Coralline Limestone Formation, a succession of sedimentary rocks that is widespread on the Maltese Islands and was deposited during the Oligocene

The arch was located near the Inland Sea, a large circular sinkhole reached by a small arch that developed along a joint in the rocks. Fungus Rock, an islet that was formed when the bridge of a natural arch collapsed leaving a stack, is also found nearby. 

The area also contains the Dwejra Tower, a 17th-century coastal watchtower built by the Order of St. John. Another natural arch, the Wied il-Mielaħ Window, is about 3.7 km northeast of Dwejra. It is, however, less known than the Azure Window.

You got to be willing to walk in a storm. 
That's what I tell people all the time.
