The Church de San Andrés is located on the site of a former church from the times of Moorish occupation. The former church had been frequented as a parish church by the patron saint of Madrid, San Isidro Labrador, and his wife Santa María de la Cabeza, who lived nearby.
The adjacent chapel of San Isidro was built at the site of the saint's house. Its construction began in 1657, after the saint was canonized in 1622. Further reconstructions were performed in 1663 and 1669, and later in 1783 and 1789. The initial construction in Baroque style was fashioned by José de Villarreal, and later Pedro de la Torre and Juan de Lobera. Much of the internal decoration, including paintings, were destroyed during the Spanish Civil War.
References:The Roman Theatre of Mérida is a construction promoted by the consul Vipsanius Agrippa in the Roman city of Emerita Augusta, capital of Lusitania (current Mérida). It was constructed in the years 16 to 15 BCE. One of the most famous and visited landmarks in Spain, the Roman Theatre of Mérida is regarded as a Spanish cultural icon and was chosen as one of the 12 Treasures of Spain.
The theatre has undergone several renovations, notably at the end of the 1st century or early 2nd century CE (possibly during the reign of Emperor Trajan), when the current facade of the scaenae frons was erected, and another in the time of Constantine I (between 330 and 340), which introduced new decorative-architectural elements and a walkway around the monument. Following the theatre"s abandonment in Late Antiquity, it was slowly covered with earth, with only the upper tiers of seats (summa cavea) remaining visible.
