Mnajdra is a megalithic temple complex built around the fourth millennium BCE; the Megalithic Temples of Malta are among the most ancient religious sites on Earth. In 1992 UNESCO recognized the Mnajdra complex and four other Maltese megalithic structures as UNESCO World Heritage Sites. In 2009 work was completed on a protective tent.
Mnajdra is made of coralline limestone, which is much harder than the soft globigerina limestone of Ħaġar Qim. The main structural systems used in the temples are corbelling with smaller stones, and post-and-lintel construction using large slabs of limestone.
The cloverleaf plan of Mnajdra appears more regular than that of Ħagar Qim, and seems reminiscent of the earlier complex at Ggantija. The prehistoric structure consists of three conjoined but not connected temples: the upper, middle and lower.
The upper temple is the oldest structure in the Mnajdra complex and dates to the Ggantija phase (3600-3200 BC). It is a three-apsed building, the doorway of which is formed by a hole cut into a large piece of limestone set upright, a type of construction typical of other megalithic doorways in Malta. This temple appears originally to have had a vaulted ceiling, but only the base of the ceiling now remain on top of the walls. The pillar-stones were decorated with pitmarks drilled in horizontal rows on the inner surface.
The middle temple was built in the late Tarxien phase (3150 – 2500 BC) and, in fact, is the most recent structure. It is formed of slabs topped by horizontal courses.
The lowest temple, built in the early Tarxien phase, is the most impressive and possibly the best example of Maltese megalithic architecture. It has a large forecourt containing stone benches, an entrance passage covered by horizontal slabs, one of which has survived, and the remains of a possibly domed roof. The temple is decorated with spiral carvings and indentations, and pierced by windows, some into smaller rooms and one onto an arrangement of stones.
The lowest temple is astronomically aligned and thus was probably used as an astronomical observation and/or calendrical site. On the vernal and the autumnal equinox sunlight passes through the main doorway and lights up the major axis. On the solstices sunlight illuminates the edges of megaliths to the left and right of this doorway.References:
Czocha Castle is located on the Lake Leśnia, what is now the Polish part of Upper Lusatia. Czocha castle was built on gneiss rock, and its oldest part is the keep, to which housing structures were later added.
Czocha Castle began as a stronghold, on the Czech-Lusatian border. Its construction was ordered by Wenceslaus I of Bohemia, in the middle of the 13th century (1241–1247). In 1253 castle was handed over to Konrad von Wallhausen, Bishop of Meissen. In 1319 the complex became part of the dukedom of Henry I of Jawor, and after his death, it was taken over by another Silesian prince, Bolko II the Small, and his wife Agnieszka. Origin of the stone castle dates back to 1329.
In the mid-14th century, Czocha Castle was annexed by Charles IV, Holy Roman Emperor and King of Bohemia. Then, between 1389 and 1453, it belonged to the noble families of von Dohn and von Kluks. Reinforced, the complex was besieged by the Hussites in the early 15th century, who captured it in 1427, and remained in the castle for unknown time (see Hussite Wars). In 1453, the castle was purchased by the family of von Nostitz, who owned it for 250 years, making several changes through remodelling projects in 1525 and 1611. Czocha's walls were strengthened and reinforced, which thwarted a Swedish siege of the complex during the Thirty Years War. In 1703, the castle was purchased by Jan Hartwig von Uechtritz, influential courtier of Augustus II the Strong. On August 17, 1793, the whole complex burned in a fire.
In 1909, Czocha was bought by a cigar manufacturer from Dresden, Ernst Gutschow, who ordered major remodelling, carried out by Berlin architect Bodo Ebhardt, based on a 1703 painting of the castle. Gutschow, who was close to the Russian Imperial Court and hosted several White emigres in Czocha, lived in the castle until March 1945. Upon leaving, he packed up the most valuable possessions and moved them out.
After World War II, the castle was ransacked several times, both by soldiers of the Red Army, and Polish thieves, who came to the so-called Recovered Territories from central and eastern part of the country. Pieces of furniture and other goods were stolen, and in the late 1940s and early 1950s, the castle was home to refugees from Greece. In 1952, Czocha was taken over by the Polish Army. Used as a military vacation resort, it was erased from official maps. The castle has been open to the public since September 1996 as a hotel and conference centre. The complex was featured in several movies and television series. Recently, the castle has been used as the setting of the College of Wizardry, a live action role-playing game (LARP) that takes place in their own universe and can be compared to Harry Potter.
