The monumental Thun Castle was built in the mid-13th century, but the current appearance dates mainly from the 16th and 17th centuries. The Spanish style gate built in 1566 in Moorish style, probably after Giorgio Thun was visited in Spain. The most famous room is the seventeenth-century Bishop's Room, entirely covered of pine wood, with a coffered ceiling and a tiled stove.
Today Thun castle is open to the public.
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.
