The Cairn of Barnenez is the largest Megalithic mausoleum in Europe. It dates from the early Neolithic Age is considered one of the earliest megalithic monuments in Europe. It is also remarkable for the presence of megalithic art. Radiocarbon dates indicate that the first phase of the monument was erected between 4850 and 4250 BC, and the second phase between 4450 and 4000 BC. Pottery found in and around the monument indicates that it underwent a period of reuse in the Bronze Age, in the 3rd millennium BC.
The cairn was first mapped in 1807, in the context of the Napoleonic cadaster. Its first scientific recognition took place in the context of an academic congress in Morlaix in 1850, when it was classified as a tumulus. Privately owned until the 1950s, the cairn was used as a quarry for paving stones. This activity, which threatened to destroy the monument, was only halted after the discovery of several of its chambers in the 1950s. The local community then took control of the site. The cairn was restored between 1954 and 1968. At the same time, vegetation was removed from the mound and systematic excavation took place in and around the monument.
Today, the Barnenez cairn is 72 m long, up to 25 m wide and over 8 m high. It is built of 13,000 to 14,000 tons of stone. It contains 11 chambers entered by separate passages. The mound has steep facades and a stepped profile. Several internal walls either represent earlier facades or served the stability of the structure. The cairn consists of relatively small blocks of stone, with only the chambers being truly megalithic in character. The monument overlooks the Bay of Morlaix, probably a fertile coastal plain at the time of its erection.
Engraved symbols occur in several of the chambers and passages. They depict bows, axes, wave symbols or snakes and a repeated U-shaped sign. One of the carved slabs is in secondary use was originally part of a different structure, an interesting parallel to the situation in several other such monuments, including Gavrinis. The symbols on the engraved blocks resemble those found in other megalithic monuments in Brittany; in broader terms they belong to the cultural phenomenon described as megalithic art. One of the recurring symbols is sometimes interpreted as an anthropomorphic depiction (the so-called 'Dolmen Goddess').
An exhibition in the modern entrance building explains the results of scientific excavation and displays some objects from the site.References:
The Church of Our Lady before Týn is a dominant feature of the Old Town of Prague and has been the main church of this part of the city since the 14th century. The church's towers are 80 m high and topped by four small spires.
In the 11th century, this area was occupied by a Romanesque church, which was built there for foreign merchants coming to the nearby Týn Courtyard. Later it was replaced by an early Gothic Church of Our Lady before Týn in 1256. Construction of the present church began in the 14th century in the late Gothic style under the influence of Matthias of Arras and later Peter Parler. By the beginning of the 15th century, construction was almost complete; only the towers, the gable and roof were missing. The church was controlled by Hussites for two centuries, including John of Rokycan, future archbishop of Prague, who became the church's vicar in 1427. The roof was completed in the 1450s, while the gable and northern tower were completed shortly thereafter during the reign of George of Poděbrady (1453–1471). His sculpture was placed on the gable, below a huge golden chalice, the symbol of the Hussites. The southern tower was not completed until 1511, under architect Matěj Rejsek.
After the lost Battle of White Mountain (1620) began the era of harsh recatholicisation (part of the Counter-Reformation). Consequently, the sculptures of 'heretic king' George of Poděbrady and the chalice were removed in 1626 and replaced by a sculpture of the Virgin Mary, with a giant halo made from by melting down the chalice. In 1679 the church was struck by lightning, and the subsequent fire heavily damaged the old vault, which was later replaced by a lower baroque vault.
Renovation works carried out in 1876–1895 were later reversed during extensive exterior renovation works in the years 1973–1995. Interior renovation is still in progress.
The northern portal is a wonderful example of Gothic sculpture from the Parler workshop, with a relief depicting the Crucifixion. The main entrance is located on the church's western face, through a narrow passage between the houses in front of the church.
The early baroque altarpiece has paintings by Karel Škréta from around 1649. The oldest pipe organ in Prague stands inside this church. The organ was built in 1673 by Heinrich Mundt and is one of the most representative 17th-century organs in Europe.
