Monkodonja is a hill fort occupied about 1800–1200 BC during the Bronze Age, located near the city of Rovinj. It is located on a hillside surrounded by a spatial area, a form of irregular ellipse stretching east-west, 160 m × 250 m. The settlement was surrounded with three concentric walls and two entrances that have explored so far (so called Western and Northern). The defensive wall surrounding the settlement was about 1 km long, about 3 m wide and at least 3 m tall. It was built by laying stone in the drywall technique. The stone was peeled off the hill, and its removal resulted in a useful surface. Approximately 1,000 people lived in the well-organized settlement: on the highest part was the acropolis, below it the upper town and still lower the lower town.
The Acropolis, where the higher layer of communities lived, had a nearly rectilinear space. In other parts of the settlement there was a crafts area. The houses differed with the position, size and manner of construction, and they were separated by passages and streets. Each had a hearth and numerous fragments of pottery pots originated from local workshops, but pots also came from the far east of the eastern Mediterranean. It was the first finding of fragments of Micens (Bronze Age) bowl in Istria. The Monkodonja was an important point in the communications of the northern Adriatic with Central Europe and the Aegean.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.
