The keep of Crupet Castle was built in the 13th century and originally consisted of a square tower surrounded by a moat. The entrance was probably protected by a drawbridge and portcullis. In the 16th century, the keep was converted to a manor house. A corner tower was added, the windows were enlarged, and the timber top floor and roof were built. The drawbridge was probably also replaced at this time. The keep is not open for visits, but is highly visible from the surrounding roads.
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.
