The Hohle Fels is a cave in the Swabian Alps that has yielded a number of important archaeological finds dating to the Upper Paleolithic age. Artifacts found in the cave represent some of the earliest examples of prehistoric art and musical instruments ever discovered. The cave consists of a tunnel of about 15 m (50 ft) and a hall holding about 6,000 m3, making the cave hall one of the largest of Southern Germany.
The first excavation took place in 1870, yielding remnants of cave bears, reindeer, mammoths and horses as well as tools belonging to the Aurignacian culture of the Upper Paleolithic. Further excavations during 1958 to 1960, 1977, and 2002 yielded a number of spectacular finds, including several specimens of prehistoric sculpture such as an ivory bird and a human-lion hybrid figure similar to the Löwenmensch figurine but only 2.5 cm tall. In 2005, one of the oldest phallic representations was discovered.
In 2008, a team from the University of Tübingen, led by archaeologist Nicholas Conard, discovered an artifact known as the Venus of Hohle Fels, dated to about 35,000 to 40,000 years ago. This is the earliest known Venus figurine and the earliest undisputed example of figurative art. The team also unearthed a bone flute in the cave, and found two fragments of ivory flutes in nearby caves. The flutes date back at least 35,000 years and are some of the earliest musical instruments ever found. In 2012, it was announced that an earlier discovery of bone flute fragments in Geißenklösterle Cave now date back to about 42,000 years, instead of 37,000 years, as earlier perceived.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
