The exact time of Ulmen Castle construction is not recorded, but it is believed that the upper castle was built around the year 1000. Its first documented mention occurred in 1074. Towards the end of the 12th and the beginning of the 13th century, it was the residence of the knight Heinrich von Ulmen, who is known for participating in the Fourth Crusade. He brought back precious treasures from this endeavor, including the famous Limburg Staurothek, which can still be seen in Limburg Cathedral today. In 1292, the castle complex was expanded with a lower castle located directly downhill. The castle complex was also once connected to the city wall to form a coordinated defense system with it, but the exact timing of this is not ascertainable.
The subsequent period was marked by local robber baronry, which flourished in the 14th century. In 1490, Ulmen became a Kurtrier administrative district. Around 1508, the legend of Knight Phillip Haust von Ulmen emerged, who was said to have been liberated from captivity in the Holy Land by his faithful castle lady.
Between 1679 and 1689, the castle was severely damaged multiple times by fires and the troops of the Sun King, Louis XIV. It was eventually destroyed by French forces. In 1789, a restoration of the upper castle took place, only to fall into decay again in the 19th century. From 1794, Ulmen was under French rule. The castle, confiscated by Napoleon, came under Prussian ownership in 1815 and was purchased in 1822 by a Cochem citizen for use as a quarry. When Ulmen was almost completely destroyed by fire in 1831, the houses were rebuilt using stones from the castle. In 1852, the municipality of Ulmen became the owner, and the townspeople used the ruins, including hosting a sheep market.
The ruins of the upper castle are owned by the municipality of Ulmen and were placed under monument protection in 1913. In 1967/68, the upper castle was restored to its current state. From the once-proud castle of a crusader, only the ring wall, remnants of the Kurtrier administrative house, an outer wall of the palas, a cistern, and a few foundation walls of other buildings remain. The remains of the lower castle have almost entirely disappeared. The upper castle is freely accessible, and events take place on its grounds regularly, including an annual medieval market every last weekend of June.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
