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:
German crusaders known as the Livonian Brothers of the Sword began construction of the Cēsis castle (Wenden) near the hill fort in 1209. When the castle was enlarged and fortified, it served as the residence for the Order's Master from 1237 till 1561, with periodic interruptions. Its ruins are some of the most majestic castle ruins in the Baltic states. Once the most important castle of the Livonian Order, it was the official residence for the masters of the order.
In 1577, during the Livonian War, the garrison destroyed the castle to prevent it from falling into the control of Ivan the Terrible, who was decisively defeated in the Battle of Wenden (1578).
In 1598 it was incorporated into the Polish-Lithuanian Commonwealth and Wenden Voivodship was created here. In 1620 Wenden was conquered by Sweden. It was rebuilt afterwards, but was destroyed again in 1703 during the Great Northern War by the Russian army and left in a ruined state. Already from the end of the 16th century, the premises of the Order's castle were adjusted to the requirements of the Cēsis Castle estate. When in 1777 the Cēsis Castle estate was obtained by Count Carl Sievers, he had his new residence house built on the site of the eastern block of the castle, joining its end wall with the fortification tower.
Since 1949, the Cēsis History Museum has been located in this New Castle of the Cēsis Castle estate. The front yard of the New Castle is enclosed by a granary and a stable-coach house, which now houses the Exhibition Hall of the Museum. Beside the granary there is the oldest brewery in Latvia, Cēsu alus darītava, which was built in 1878 during the later Count Sievers' time, but its origins date back to the period of the Livonian Order. Further on, the Cēsis Castle park is situated, which was laid out in 1812. The park has the romantic characteristic of that time, with its winding footpaths, exotic plants, and the waters of the pond reflecting the castle's ruins. Nowadays also one of the towers is open for tourists.
