The Caliphal Baths are Arab baths in Córdoba. They are situated in the historic centre which was declared a World Heritage Site by UNESCO in 1994. The hammam ('baths) are contiguous to the Alcázar andalusí; ablutions and bodily cleanliness were an essential part of a Muslim's life, mandatory before prayer, besides being a social ritual.
The baths were constructed in the 10th century, under the Caliphate of Al-Hakam II for the enjoyment of the caliph and his court. Between the 11th and 13th centuries, they were used by Almoravids and Almohads, their dynasties noted by the plaster-carved acanthus motif and epigraphic bands of the era, which are stored in the Archaeological and Ethnological Museum of Cordoba. The remains of the baths were found accidentally in 1903 in the Campo Santo de los Mártires, and were subsequently buried. Between 1961 and 1964, a group of city historians recovered them.
The Caliphal Baths have different sections of cold, warm and hot water baths. Architectural details include rooms with masonry walls, semicircular arches, and columns with capitals. The ceiling is punctuated by cut-outs of stars.
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.
