The Estrela Basilica is a former carmelite convent built by order of Queen Maria I of Portugal, as a fulfilled promise for giving birth to a son (José, Prince of Brazil). The official name of the church is the Basilica of the Sacred Heart of Jesus. Construction started in 1779 and the basilica was finished in 1790, after the death of José caused by smallpox in 1788. The Estrela Basilica was the first church in the world dedicated to the Sacred Heart of Jesus.
The huge church has a giant dome, and is located in a hill in what was at the time the western part of Lisbon and can be viewed from far away. The style is similar to the Mafra National Palace, in late baroque and neoclassical. The front has two twin bell towers and includes statues of saints and some allegoric figures.
A large quantity of grey, pink and yellow marble was used in the floor and walls, in intricate geometric patterns, one of the most beautiful in European churches. Several paintings by Pompeo Batoni also contribute to a balanced design. The tomb of the Queen Mary I is on the right transept. A famous nativity scene made by sculptor Joaquim Machado de Castro, with more than 500 figures in cork and terra cotta is a major attraction to visitors.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
