The Teatro Massimo Vittorio Emanuele is the biggest in Italy, and one of the largest of Europe. Construction started in 1874, but was stopped for eight years from 1882 until 1890. Finally, on 16 May 1897, twenty-two years after the laying of the foundation stone, it was inaugurated with a performance of Verdi's Falstaff conducted by Leopoldo Mugnone.
Basile was inspired by ancient and classical Sicilian architecture and, thus, the exterior was designed in the high neoclassical style incorporating elements of the Greek temples at Selinunte and Agrigento. Realized in the late-Renaissance style, the auditorium was planned for 3,000 people, but, in its current format, it seats 1,381, with 7 tiers of boxes rising up around an inclined stage, and shaped in the typical horseshoe style.
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.
