Ehrenburg Palace was built by Johann Ernst, Duke of Saxe-Coburg, in 1543-47. It replaced the Veste Coburg as the Dukes' city Residenz. The new city palace was built around a dissolved Franciscan monastery.
According to tradition, the palace was named Ehrenburg ('Palace of Honour') by Emperor Charles V for having been constructed without the use of forced labour.
In 1690, a fire destroyed the northern part of the palace. This was an opportunity for Albert V, Duke of Saxe-Coburg, who had a new Baroque style palace built in 1699.
In the 19th century, Ernst I had the palace redesigned by Karl Friedrich Schinkel in Gothic Revival style, beginning in 1810. Between 1816 and 1840 the state apartments were redesigned in the French Empire style.
The palace is used as a museum today. Among other exhibits, it features art galleries with works by Lucas Cranach the Elder, Dutch and Flemish artists of the 16th and 17th centuries as well as romantic landscape paintings.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
