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 only response to this international call was by Gozitan developer Joseph Portelli, proposing to construct a hotel within a quarry close to the site of the Azure Window. The project would also include an interpretation area, a diving centre, an interactive museum, a sky observation centre and transport facilities. In August 2018 it was announced that the government does not plan to proceed with this proposal. In late 2018, the Russian architect Svetozar Andreev of Hoteì Russia, in collaboration with Elena Britanishskaya, announced a proposal to construct a steel structure on the site of the Azure Window. Entitled The Heart of Malta, the project consists of a structure with polygonal mirrored steel faces, having its size and proportions based on that of the former natural arch. The structure is to include five floors containing over of exhibition space, with each floor representing a period of Maltese history. A central spiral will connect the floors together. This proposal drew mixed reactions from the public. Most respondents to online polls were in favour. However, the project has also been criticized since the area is a marine park and the intervention would destroy the underwater remains of the original Azure Window. Moreover, the foundations would have to rest in the sea at a depth of over , and the site is prone to heavy storms. In August 2019, a new street in the nearby village of San Lawrenz was named Triq it-Tieqa tad-Dwejra (Dwejra Window Street) in memory of the natural landmark. Geology The Azure Window was a natural arch with a height of about and a span of around . It was at the tip of a headland known as Dwejra Point. The arch was 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 Formation is subdivided into two Members, Member A and Member B. Member A formed the arch's base and pillars, and Member B formed much of the unsupported top of the arch. Member A, ca. 20 m in thickness, mainly consists of the fossils of
