Castelvecchio ('Old Castle') is the most important military construction of the Scaliger dynasty that ruled the city in the Middle Ages. The castle stands on the probable location of a Roman fortress outside the Roman city. Lord Cangrande II della Scala had it built along with its bridge across the Adige River as a deterrent to his powerful neighbors such as Venice, the Gonzaga and the Sforza families. Construction was carried out between 1354 and 1376 (Cangrande died in 1359). The fortified bridge was intended to allow the seigniors to escape safely northwards to the Tyrol in the event of a rebellion or a coup d'état (the Scaligeri were allies of the Holy Roman Empire) and when they eventually lost their hold on Verona, its surviving members left Italy to found a German branch of the family.
Later, during the Venetian domination, slits were added to defend it with cannons. The castle was damaged by French troops during the Napoleonic Wars (1796-7), in retaliation to the Pasque Veronesi, when the local population staged a violent anti-French revolt. Napoleon had chosen to stay in Castelvecchio on his trips to Verona, but his widespread and arbitrary requisitions of citizens' and churches' property, the massive draft of male workers into the French army prompted the resistance that eventually drove out the invaders.
Under the Austrians, Castelvecchio was turned into barracks. In 1923 the castle was restored, as well as in 1963-1965.
The castle is powerful and compact in its size with very little decoration - one square compound built in red bricks, one of the most prominent examples of Gothic architecture of the age, with imposing M-shaped merlons running along the castle and bridge walls. It has seven towers, a superelevated keep with four main buildings inside. The castle is surrounded by a ditch, now dry, which was once filled with waters from the nearby Adige.
Castelvecchio is now home to the Castelvecchio Museum and the local officer's club.
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.
