Bergpark Wilhelmshöhe is a unique landscape park in Kassel. The area of the park is 2.4 square kilometres, making it the largest European hillside park, and second largest park on a mountain slope in the world. Descending a long hill dominated by a giant statue of Hercules, the monumental water displays of Wilhelmshöhe were begun by Landgrave Carl of Hesse-Kassel in 1689 around an east-west axis and were developed further into the 19th century. Reservoirs and channels behind the Hercules Monument supply water to a complex system of hydro-pneumatic devices that supply the site’s large Baroque water theatre, grotto, fountains and 350-metre long Grand Cascade. Beyond this, channels and waterways wind across the axis, feeding a series of dramatic waterfalls and wild rapids, the geyser-like Grand Fountain which leaps 50m high, the lake and secluded ponds that enliven the Romantic garden created in the 18th century by Carl’s great-grandson, Elector Wilhelm I. The great size of the park and its waterworks along with the towering Hercules statue constitute an expression of the ideals of absolutist Monarchy while the ensemble is a remarkable testimony to the aesthetics of the Baroque and Romantic periods.
Schloss Wilhelmshöhe was damaged by Allied bombs in World War II. From 1968 to 1974, it was rebuilt as an art museum. It houses a wallpaper collection, a collection of Graeco-Roman antiques, and a gallery of Old Masters paintings. The collection focuses on the 16th and 17th century, containing masterpieces by German, Italian, French and Spanish painters. It comprises the second-largest collection of Rembrandts in Germany. Rembrandt's famous 'Saskia' and 'The Man with the Slouch Hat' by Frans Hals are among them.
On 23 June 2013 Wilhelmshöhe was proclaimed as a World Heritage Site during the UNESCO meeting in Phnom Penh.
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.
