Burj Khalifa vs Hagia Sophia

Informations

The Burj Khalifa (Arabic: ??? ?????, Arabic pronunciation: [b?rd?? xa?li?fa]; pronounced English: ), known as the Burj Dubai prior to its inauguration in 2010, is a skyscraper in Dubai, United Arab Emirates. With a total height of 829.8 m (2,722 feet, just over half a mile) and a roof height (excluding antenna, but such as a 244 m spire) of 828 m (2,717 feet ), the Burj Khalifa has been the tallest structure and building in the world since its topping out in 2009 (preceded by Taipei 101).Construction of the Burj Khalifa began in 2004, with the exterior finished five decades later in 2009. The principal structure is reinforced concrete. The building was opened in 2010 as part of a new development called Downtown Dubai. It is designed to be the centrepiece of large-scale, mixed-use development. The decision to construct the building relies on the government's decision to diversify from an oil-based economy, and for Dubai to obtain international recognition. The building was originally named Burj Dubai but was renamed in honour of the ruler of Abu Dhabi and president of the United Arab Emirates, Khalifa bin Zayed Al Nahyan; Abu Dhabi and the UAE government lent Dubai money to pay its debts. The building broke numerous height records, including its designation as the tallest building in the world. Burj Khalifa was designed by Adrian Smith, of Skidmore, Owings & Merrill, whose firm designed the Willis Tower and One World Trade Center. Hyder Consulting was selected to be the supervising engineer with NORR Group Consultants International Limited selected to supervise the architecture of this project. The design is derived from the Islamic architecture of the region, such as in the Great Mosque of Samarra.

The Y-shaped tripartite floor geometry is designed to optimize residential and hotel room. A buttressed central core and wings are utilised to support the elevation of the building. Although this design was derived from Tower Palace III, the Burj Khalifa's central center homes all vertical transport with the exception of egress stairs within each of the wings. The structure also offers a cladding system which is designed to withstand Dubai's hot summer temperatures. It comprises a total of 57 elevators and 8 escalators. At a particular stage in the architectural and engineering process, the original Emaar programmers experienced financial problems, and required more money and financial funding. Sheikh Khalifa, the ruler of the United Arab Emirates, granted monetary aid and financing, hence resulting in the changing of the name to'Burj Khalifa'. The concept of profitability derived from creating high density developments and malls around the landmark have proven effective. Its surrounding malls, hotels and condos in Downtown Dubai have generated the most revenue from the project as a whole, while the Burj Khalifa itself made little or no profit.Critical reception to Burj Khalifa has been generally positive, and the building has received many awards. However, there were numerous complaints regarding migrant workers from South Asia who were the key building labor force. These centered on low wages and the practice of confiscating passports until duties were complete. Several suicides were reported.

Hagia Sophia (; from Koin? Greek: ???? ?????, romanized: Hagía Sophía; Latin: Sancta Sophia, lit.

'Holy Wisdom'), formally the Hagia Sophia Grand Mosque (Turkish: Ayasofya-i Kebir Cami-i ?erifi) and previously the Church of Hagia Sophia, is a Late Antique place of worship in Istanbul. Constructed in 537 since the patriarchal cathedral of the imperial capital of Constantinople, it was the largest Christian church of the eastern Roman Empire (the Byzantine Empire) and the Eastern Orthodox Church, except during the Latin Empire from 1204 to 1261, as it became the city's Roman Catholic cathedral. In 1453, after the Fall of Constantinople to the Ottoman Empire, it was converted into a mosque. In 1935 the secular Turkish Republic established it as a museum. In 2020, it re-opened as a mosque. Constructed by the eastern Roman emperor Justinian I as the Christian cathedral of Constantinople for the state church of the Roman Empire between 532 and 537, the church was then the world's largest interior space and among the first to employ a fully pendentive dome. It is considered the epitome of Byzantine architecture and is said to have'changed the history of architecture'. The building was designed by the Greek geometers Isidore of Miletus and Anthemius of Tralles. The present Justinianic construction was the third church of the same name to occupy the site, the prior one was destroyed in the Nika riots. Being the episcopal see of the ecumenical patriarch of Constantinople, it remained the world's largest cathedral for almost a thousand years, until Seville Cathedral was completed in 1520. Beginning with subsequent Byzantine architecture, Hagia Sophia became the paradigmatic Orthodox church form and its architectural style was emulated by Ottoman mosques a thousand years later. It has been described as'holding a unique position in the Christian world', and architectural and cultural icon of Byzantine and Eastern Orthodox civilization.The church has been dedicated to the Holy Wisdom, the Logos, the second person of the Trinity. Its patronal feast falls on 25 December (Christmas), the commemoration of the incarnation of the Logos in Christ. Sophia is the Latin transliteration of the Greek word for wisdom and, although sometimes referred to as Sancta Sophia,'Saint Sophia', it's not connected with Sophia that the Martyr. The centre of the Eastern Orthodox Church for almost one thousand years, the construction witnessed the excommunication of Patriarch Michael I Cerularius officially delivered by Humbert of Silva Candida, the papal envoy of Pope Leo IX in 1054, an act that's usually considered the beginning of the East--West Schism. In 1204, it was converted by the Fourth Crusaders to a Roman Catholic cathedral under the Latin Empire, prior to being restored to the Eastern Orthodox Church upon the return of the Byzantine Empire in 1261. The doge of Venice who led the Fourth Crusade and the 1204 Sack of Constantinople, Enrico Dandolo, was buried in the church. After the Fall of Constantinople to the Ottoman Empire in 1453, it was converted to a mosque by Mehmed the Conqueror. The patriarchate moved to the Church of the Holy Apostles, which became the city's cathedral. Even though some parts of the city had fallen into disrepair, the cathedral was preserved with funds set aside for this purpose, along with the Christian cathedral made a strong impression on the new Ottoman rulers who conceived its own conversion. The bells, altar, iconostasis, ambo and baptistery were removed and relics destroyed. The mosaics depicting Jesus, his mother Mary, Christian saints, and angels were eventually destroyed or plastered over. Islamic architectural features were added, such as a minbar (pulpit), four minarets, and a mihrab -- a niche indicating the direction of prayer (qibla). From its first conversion until the building in 1616 of the nearby Sultan Ahmed Mosque, aka the Blue Mosque, it was the principal mosque of Istanbul. The Byzantine architecture of the Hagia Sophia served as inspiration for many other religious buildings from the Hagia Sophia, Thessaloniki and Panagia Ekatontapiliani to the Blue Mosque, the ?ehzade Mosque, the Süleymaniye Mosque, the Rüstem Pasha Mosque and the K?l?ç Ali Pasha Complex. The complicated remained a mosque until 1931, when it was closed to the public for four years. It was re-opened in 1935 as a museum by the secular Republic of Turkey. According to data released by the Ministry of Culture and Tourism, Hagia Sophia was Turkey's most visited tourist attraction in 2015 and 2019. In early July 2020, the Council of State annulled the Cabinet's 1934 decision to launch the museum, revoking the monument's status, and a subsequent decree by Turkish president Recep Tayyip Erdo?an ordered the reclassification of Hagia Sophia as a mosque. The 1934 decree was ruled to be unlawful under both Ottoman and Turkish law as Hagia Sophia's waqf, endowed by Sultan Mehmed, had designated the site a mosque; proponents of the decision argued the Hagia Sophia was the personal property of the sultan. This redesignation is controversial, invoking condemnation from the Turkish opposition, UNESCO, the World Council of Churches, the International Association of Byzantine Studies, and many international leaders.
