The Fountain of Campo das Hortas is an example of the model of fountain seeded throughout the 16th and 17th century Portugal, which was first promoted in 1554 by João Lopes o Velho in Viana do Castelo.
On 8 March 1594, a contract was issued, by Archbishop Agostinho de Jesus for the Archdiocese of Braga, to master-mason Manuel Luis to construct a fountain in the Campo de Santa Ana. There was no indication if the project was completed within the year or pre-defined time. By the 19th century, the fountain was relocated to the Campo das Hortas.
The fountain is implanted in a harmonious location, isolated in the centre of garden space fronting the Arco da Porta Nova. Built on an octagonal base, it consists of alternating four-steps divided by green-space, with a circular tank at the top of the staircase. The circular tank is marked by a column with bowl, decorated in grotesque animals ordered by six spouts, which is repeated in the smaller bowl. From the second segment the column is decorated by three sections: the first with six figures at the spouts, the second with the coat-of-arms of Archbishop D. Baltasar Limpo, and the third a cylindrical body decorated with four rounded spirals. The top of the spire is decorated with an armillary sphere and cross in metal.
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.
