Okoř is a castle on a low rocky promontory in Okoř, north-west of Prague, about 15 kilometres from the city centre. In 1228 a stronghold was built in the small hamlet of Okoř. It was later modified into a Gothic castle, founded in 1359 by Frantisek Rokyčansky, a wealthy burgher of Prague's Old Town. It was later modified by comprehensive Late Gothic remodelling by the Lords of Donin. In 1518, during the reign of Bořitas of Martinice, the castle was turned into a residence in the Renaissance style.
During the Thirty Years' War the castle was heavily damaged and then restored in the Baroque style. It underwent further extension in the second half of the 15th century, and in the 17th century it was owned by Jesuits. Following their departure after the Jesuit order was discontinued in Bohemia, the Okoř castle became deserted in the late 18th century and slowly began to deteriorate.
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.
