The Hypogeum of Ħal-Saflieni is a subterranean structure dating to the Saflieni phase (3300-3000 BC) in Maltese prehistory. It is often simply referred to as the Hypogeum, literally meaning 'underground' in Greek. The Hypogeum is thought to have been originally a sanctuary, but it became a necropolis in prehistoric times, and in fact, the remains of more than 7,000 individuals have been found. It is the only known prehistoric underground temple in the world. The Hypogeum is UNESCO World Heritage Site.
The Ħal Saflieni Hypogeum is a complex made up of interconnecting rock-cut chambers set on three distinct levels. Earliest remains at the site date back to about 4000BC, and the complex was used over a span of many centuries, up to c. 2500 BC.
The uppermost level consists of a large hollow with burial chambers on its sides. This hollow was probably originally exposed to the sky and excavations in the early 1990s indicate that there might also have been a monumental structure marking the entrance. A doorway leads to the Middle Level, which contains some of the best known features of the Hypogeum such as the intricate red ochre wall paintings and the beautifully carved features in imitation of architectural elements common in contemporaneous Megalithic Temples. The deepest of the three levels is known as the Lower Level, which is accessed down seven steps in the chamber popularly known as the ‘Holy of Holies’.
The Hypogeum was first opened to visitors in 1908 and since then it has been visited by many thousands of people. Unfortunately, this has had a toll on the delicate microclimate of the site which has affected the preservation of the site and the unique red ochre paintings. For this reason, after a conservation project which saw the site closed for 10 years between 1990 and 2000, a new system was established in which only 10 visitors an hour are allowed in for a maximum of 8 hours a day, complemented by an environmental control system which keeps temperature and humidity at required levels.References:
The Old Town Hall of Wrocław is one of the main landmarks of the city. The Old Town Hall's long history reflects developments that have taken place in the city since its initial construction. The town hall serves the city of Wroclaw and is used for civic and cultural events such as concerts held in its Great Hall. In addition, it houses a museum and a basement restaurant.
The town hall was developed over a period of about 250 years, from the end of 13th century to the middle of 16th century. The structure and floor plan changed over this extended period in response to the changing needs of the city. The exact date of the initial construction is not known. However, between 1299 and 1301 a single-storey structure with cellars and a tower called the consistory was built. The oldest parts of the current building, the Burghers’ Hall and the lower floors of the tower, may date to this time. In these early days the primary purpose of the building was trade rather than civic administration activities.
Between 1328 and 1333 an upper storey was added to include the Council room and the Aldermen’s room. Expansion continued during the 14th century with the addition of extra rooms, most notably the Court room. The building became a key location for the city’s commercial and administrative functions.
The 15th and 16th centuries were times of prosperity for Wroclaw as was reflected in the rapid development of the building during that period. The construction program gathered momentum, particularly from 1470 to 1510, when several rooms were added. The Burghers’ Hall was re-vaulted to take on its current shape, and the upper story began to take shape with the development of the Great Hall and the addition of the Treasury and Little Treasury.
Further innovations during the 16th century included the addition of the city’s Coat of arms (1536), and the rebuilding of the upper part of the tower (1558–59). This was the final stage of the main building program. By 1560, the major features of today’s Stray Rates were established.
The second half of the 17th century was a period of decline for the city, and this decline was reflected in the Stray Rates. Perhaps by way of compensation, efforts were made to enrich the interior decorations of the hall. In 1741, Wroclaw became a part of Prussia, and the power of the City diminished. Much of the Stray Rates was allocated to administering justice.
During the 19th century there were two major changes. The courts moved to a separate building, and the Rates became the site of the city council and supporting functions. There was also a major program of renovation because the building had been neglected and was covered with creeping vines. The town hall now has several en-Gothic features including some sculptural decoration from this period.
In the early years of the 20th century improvements continued with various repair work and the addition of the Little Bear statue in 1902. During the 1930s, the official role of the Rates was reduced and it was converted into a museum. By the end of World War II Town Hall suffered minor damage, such as aerial bomb pierced the roof (but not exploded) and some sculptural elements were lost. Restoration work began in the 1950s following a period of research, and this conservation effort continued throughout the 20th century. It included refurbishment of the clock on the east facade.
