Steiner Tor is a-preserved gate, originally built in the late 15th century but refashioned in the Baroque style in the city of Krems an der Donau, in the Wachau valley. It is considered the symbol of the city. Until the last third of the 19th century, the city of Krems was surrounded by a wall. This was systematically razed, and three gates were also removed. From 2005, celebrating the 700-year anniversary of the city rights, the Steiner Tor was restored as much to its original as possible.
Outside the portal are towers flanking both sides, which, like the lower floor of the gate, date from the late Middle Ages. On the right of the archway is a small stone coat of arms mentioning Emperor Friedrich III, and the year 1480 in Roman numerals. This is believed to date the restoration of the fortifications that had become necessary because of the destruction wrought by Hungarian troops in 1477. The tower building dates from much more recently, and dates to the Baroque period during the reign of Maria Theresa, 1756. Outside the gate, the Steiner Tor was originally threatened by flooding from the Danube. On the inner side of the stone door is a mounted memorial which commemorates such a disaster in 1573.
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.
