Perhaps the least visited of Madrid's major art treasures are the stunning frescoes painted by Francesco Goya that fill the Hermitage of San Antonio de la Florida. The little chapel, along the banks of the Manzanares River behind the Royal Palace, hosts an annual festival in honor of Saint Anthony of Padua, but it's the interior that has become a place of pilgrimage for art lovers. Among Goya's finest works, the frescoes illustrate the theme of the miracle performed by Saint Anthony, while also depicting scenes of everyday life in Madrid. The frescoes reveal Goya's boldness of artistic style and revolutionary painting techniques. They were painted at a turning point in Goya's career and are considered a precursor of modern painting. The chapel is designated a national monument and is no longer used for religious services to protect the frescoes.
The shrine was originally erected 15 kilometres ( mi) south of Aswan  in Upper Egypt , very close to the first cataract of the Nile and to the great religious center in Philae dedicated to the goddess Isis . In the early 2nd century BC, Adikhalamani (Tabriqo), the Kushite king of Meroë , started its construction by building a small single-room chapel dedicated to the god Amun .  It was built and decorated in a similar design to the later Meroitic chapel on which the Temple of Dakka is based.  Later, during the reigns of Ptolemy VI , Ptolemy VIII , and Ptolemy XII of the Ptolemaic dynasty , it was extended on all four sides to form a small temple, 12 by 15 metres (39 ft × 49 ft), which was dedicated to Isis of Philae. The Roman emperors Augustus and Tiberius completed its decorations. 
Of course, there were some serious logistics involved in shipping an ancient temple over an ocean. Debod was first deconstructed in Egypt and shipped to Spain in pieces. Then Madrid carefully rebuilt the temple at its current location, stone by stone, on the edge of the Parque de Oeste near the Plaza de España. The process was long and tedious, because the reconstruction needed to be done correctly to ensure no parts of the temple were damaged. It was inaugurated by Carlos Arias Navarro, the mayor of Madrid, in July 1972, and then opened to the public.
