Schalun Castle, also known colloquially as Wildschloss, was constructed probably during the second half of the 12th century or around the turn of the 12th century. The first written record about the castle comes from 1237. In it, it was also first referred to by name, as 'Schalun'. Archeological digs made in recent decades have revealed only small amounts of artefacts from the medieval and early modern period, suggesting that the castle might have been cleared and burned down at a later point in its history. In the 18th century, the castle came into the possession of the then Prince Regnant of Liechtenstein. The ownership of the castle ruin was handed over to the Municipality of Vaduz in 1933. Today, the best preserved parts of the castle are its grand hall and the remaining section of its keep.
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.
